Here are some 5G trends for year 2020:
It looked like 5G and wireless dominated the airways in 2019. It seems that year 2020 will be a real test for 5G if it will really take on or fails to full-fill the big expectations. It seems that 5G networks are available at some place here and there from many operators, but 5G end user devices are not yet widely available or desired. New year will bring more 5G base stations.
5G: How Much is Real vs. Marketing? Is 5G ready for prime time? Breaking down the marketing hype versus what’s really going on in the industry. Marketing claims 5G is pervasive. The question is when: 2020 or is it 2025?
First, let’s define 5G also known as 5G New Radio, or 5G NR:
There is sub-6-GHz 5G for the cellphone protocol that requires LTE: 5G NSA.
There is sub-6-GHz standalone 5G: 5G SA.
There is 20- to 60-GHz 5G: 5G mmWave.
It seems that 2020 will be the real test for 5G devices as the 5G device mass market has not yet really started. Samsung says it shipped 6.7M+ Galaxy 5G phones globally in 2019, accounting for 53.9% of the 5G phone market (Galaxy S10 5G and the Galaxy Note 10 Plus 5G). 2020 is expected to be an interesting year for 5G growth across the smartphone market. Increased 5G rollouts by carriers means that customers will presumably be more interested in actually buying 5G devices. One June 2019 forecast made by Canalys has global 5G smartphone shipments crossing 4G smartphone shipments in 2023.
5G will be integrated to some PCs. Dell debuts a new Latitude 9510 laptop with built-in 5G, to launch March 26.
Ericsson says they are now 5G networks leader according to Ericsson ylitti odotukset kirkkaasti: ”Olemme 5g-johtaja” article. Nokia has cut its outlook for this year and next because of the need to step up its investments in 5G but ‘We don’t have a 5G problem,’ says Nokia’s head of software.
5G will be a good growing market for test device manufacturers as engineers will once again need to sharpen their skill sets and adopt new design and testing techniques. A lot of 5G Component Characterization and Test will be needed.Delivering 5G Devices to Market Will Bank on OTA Testing.
Network side needs also testing equipment. One approach being adopted to gain ground in the race to 5G involves the rapid prototyping and testing of network architectures. There is need for programmable RF devices. Industry seems to want their own private networks.
5G components are available from many sources already. The typical RF component suppliers are all providing 5G solutions: Avago/Broadcom, Huawei, MediaTek, Murata/pSemi (previously known as Peregrine), Qualcomm, Qorvo, Samsung, and Skyworks.
Challenges: Even the sub-6-GHz versions have technical issues in that the 5G target “air time” latency is 1 to 4 ms. Typical RF component manufacturers appear to be providing components that focus only on the sub-6-GHz frequency bands. The geopolitical situation relative to 5G also adds confusion to the 5G timeline.
There are many technical issues must be considered in the utilization of mmWave: mmWave frequencies travel relatively small distances. the mmWave transmitters consume a considerable amount of transmit power, providing additional challenges for battery-operated devices.
5G in automotive: The automobile industry is experiencing exponential growth of self-driving features, and this trend is expected to continue. 5G network connections are expected to have a major influence on the development of self-driving cars making them faster, smarter, and safer. Where is car technology going in 2020?
As 5G work has started for many installers and marketers, the the researchers are already thinking about the nest step Beyond 5G chips. They are already planning technologies that could enable high-speed wireless devices beyond the 5G standard.

Nokian ja Googlen tekniikka tuo puhelimeen useita samanaikaisia nettiyhteyksiä https://www.is.fi/digitoday/mobiili/art-2000009028041.html
VERKKOLAITEVALMISTAJA Nokia kertoo kehittäneensä yhteistyössä Googlen kanssa uuden 5g-verkon toiminnon, joka mahdollistaa laitteen verkkoyhteyden jakamisen eri kaistoille sovelluskohtaisesti.
Verkon kaistoihin jakaminen (englanniksi network slicing) tarkoittaa käytännössä sitä, että operaattorit kykenevät jakamaan saman fyysisen verkon useaan virtuaaliseen alaverkkoon. Jokainen kaista voi olla ominaisuuksiltaan ja suorituskyvyltään eri tasoilla toisiin verrattuna, vaikka ne sijaitsevat saman verkon sisällä.
Nokian ja Googlen uusi teknologia voi toimia esimerkiksi niin, että yritysasiakas voi lähettää liiketoiminalle kriittistä tietoa turvallisella ja erittäin nopealla verkon kaistalla samalla, kun hän osallistuu videopuheluun toisella kaistalla. Kuluttajille tämä voi Nokian tiedotteen mukaan tarkoittaa esimerkiksi erityisten pilvipelaamiseen tai suoratoistoon suunniteltuja kaistoja.

Uusi NTN-tekniikka: 5G korvaa satelliittipuhelimet
https://etn.fi/index.php/13-news/13928-uusi-ntn-tekniikka-5g-korvaa-satelliittipuhelimet
Kesällä 3GPP-järjestössä hyväksytty uusi 5G-standardi eli Release 17 tuo monia uudistuksia ja laajennuksia 5G-verkkostandardeihin. Yksi uudistuksista on NTN (Non-terrestrial networks), joka laajentaa 5G-yhteydet avaruuteen. Mediatek on jo demonnut NTN-datansiirtoa yhdessä mittauslaitevalmistaja Rohde & Schwarzin kanssa.
Uuden 5G-standardin NTN-osa tuo mukaan uusia verkkotopologioita. Niiden avulla linkit toimivat sekä korkealla että matalalla radalle lentäviin satelliitteihin. Tarkoitus ei ole, että NTN kattaa vain puhelu- ja laajakaistapalvelut, vaan yhteyksien pitää tukea myös NB-IoT- ja LTE-M-tyypin IoT-linkkejä.

Reliance Jio to spend $25B on 5G rollout, debut in October and reach every town by 2023 end
https://techcrunch.com/2022/08/29/reliance-jio-to-debut-5g-in-october-reach-all-by-2023-end/?tpcc=tcplusfacebook
Reliance Jio Infocomm, India’s top telecom mobile operator, has earmarked a spending of $25 billion on the rollout of its 5G services that it plans to debut in key cities this Diwali in October, the company announced at its annual general meeting Monday. The company, which has amassed over 421 million telecom subscribers, will extend its 5G network to “every town” in India by the end of 2023, it said.
Reliance Industries’ Mukesh Ambani said Jio will deploy a standalone 5G architecture that doesn’t rely on existing 4G network and hence offers superior performance.
The company can connect 100 million homes with its 5G network and further accelerate its connectivity ambitions with fixed broadband services, he said, without sharing tariff details.
The company unveiled the AirFiber, a wireless plug-and-play 5G hotspot that doesn’t require fiber cables to reach homes, he said.
“Jio has developed a JioAirFiber Home Gateway, which is a wireless, simple, single-device solution to have a Wi-Fi hotspot in a home, connected to ultra-high-speed internet using true 5G,” it said.

Nokia ja Google demosivat viipalointia
https://etn.fi/index.php/13-news/13938-nokia-ja-google-demosivat-viipalointia
Nokia ja Google ovat onnistuneesti kokeilleet innovatiivisia verkon viipaleiden valintatoimintoja 4G/5G-verkoissa käyttämällä URSP-tekniikkaa (UE Route Selection Policy) ja Googlen Pixel 6 Pro -puhelimia. Laitteissa oli käytössä vasta valmistumassa oleva Android 13 -käyttöjärjestelmä.
URSP-ominaisuudet mahdollistavat älypuhelimen yhteyden useisiin verkkoviipaleisiin (slices) samanaikaisesti eri yritys- ja kuluttajasovellusten kautta tilaajan erityisvaatimuksista riippuen. Nokian Tampereen tutkimuskeskuksessa tehty testi sisälsi myös LTE-5G New Radio-tekniikan viipaloinnin yhteensopivuuden testaamisen.
URSP-ominaisuudet laajentavat verkon viipalointia uudentyyppisiin sovelluksiin ja käyttötapauksiin, jolloin verkkoviipaleita voidaan räätälöidä verkon suorituskyvyn, liikenteen reitityksen, latenssin ja suojauksen perusteella. Yritysasiakas voi esimerkiksi lähettää liiketoimintaan liittyviä arkaluontoisia tietoja käyttämällä suojattua ja tehokasta verkkolohkoa, kun hän osallistuu videopuheluun toisella osuudella samaan aikaan.

Say Goobye to “No Cell Service”, SpaceX Announces Industry-Changing Starlink V2 Satellites
https://www.gizmochina.com/2022/08/26/spacex-announces-industry-changing-starlink-v2-satellites/
in 2022, technology has matured far enough that humans have finally found a solution to tackle the problem of providing cell service even in remote places that were previously unreachable by traditional cell signals.
In a live event today, US telecommunications provider, T-Mobile alongside the globally renowned aerospace company, SpaceX, introduced Starlink V2, the satellites that can directly transmit cell signals to mobile phones and Tesla cars from space.
The announcement today was mainly focused on Starlink V2’s implementation in the US with telecommunications provider T-Mobile. Under the new plan which they dubbed Coverage Above and Beyond, both companies will establish a new network using T-Mobile’s existing mid-band spectrum across the United States.
The main advantage of using an existing spectrum is that the majority of smartphones on its existing network will be able to connect to the new network without any need for new equipment.
Leveraging on SpaceX’s Starlink V2 satellites, the new network aims to eliminate cellular dead zones across the country.
Chief Engineer of SpaceX, Elon Musk says that for the new network, the deployment of Starlink V2 satellites will work great for texting and voice calls but not for usages that require high bandwidth. This is mainly because each cell zone under the new network can only deliver 2 to 4Mbps.
Although SpaceX’s Starlink V2 technology is only currently implemented in the USA, both SpaceX and T-Mobile shared their vision for expanding Coverage Above and Beyond globally, issuing an open invitation to the world’s carriers to collaborate for truly global connectivity.

In a first, Comcast and Charter both failed to grow internet subscribers in Q2 2022, as T-Mobile and Verizon roll out cheaper home internet powered by 5G — For years, Comcast and other cable companies have leaned on a simple strategy to offset the effects of cord-cutting …
Comcast and Charter face a grim new reality: actual competition
https://www.fastcompany.com/90782532/comcast-and-charter-face-a-grim-new-reality-actual-competition
Cheap home internet from T-Mobile and Verizon is here, and it’s already threatening the cable giants.
For years, Comcast and other cable companies have leaned on a simple strategy to offset the effects of cord-cutting: Charge a steep price on home internet service, and enjoy soaring profits thanks to little or no competition.
That strategy may now be in jeopardy. Comcast’s internet subscriber growth was essentially flat last quarter, while Charter lost 21,000 Spectrum internet subscribers. For both companies, it’s the first time they’ve failed to grow their home internet businesses in a given quarter.
The reason isn’t a mystery, either: All around the country, T-Mobile and Verizon have been rolling out cheap home internet service powered by their 5G networks, at last giving customers an alternative where none previously existed. In an earnings call, Comcast CEO Brian Roberts pointed to those carriers as a reason its broadband growth has hit a wall.
It’s a rude awakening for cable companies, whose broadband monopolies in many markets have allowed them to raise prices—and, in Comcast’s case, enforce data caps. While Comcast and Charter have tried to downplay the threat posed by wireless home internet, experts say the competition is here to stay.

5G Densification: Making 5G a Working Reality
Aug. 26, 2022
With 5G cellular forging ahead, understanding the economics behind the investment decisions is crucial to overcoming complexities around deploying 5G.
https://www.mwrf.com/technologies/systems/article/21249378/nxp-semiconductors-5g-densification-making-5g-a-working-reality
As the rollout for 5G cellular continues, network operators are modifying the existing infrastructure. They’re adding what’s needed to support the higher rates, greater device density, and lower latency we’ll need to run advanced 5G use cases, now and in the future.
Operators have done this kind of work before, moving cellular from 2G to 3G and 4G, but this time it’s different. 5G is more than just an overlay on the previous generation—it’s a seismic shift that brings fundamental change at every level. Preparing for 5G operation means having to deal with new technologies and new techniques, from recently opened bands of unfamiliar spectrum and complex active antenna architectures to virtualization and machine-learning algorithms.

Tier 1 U.S. operator taps EXFO for 5G network testing from core to edge to last mile
July 29, 2022
As noted by the network test equipment provider, “Integral to 5G, edge computing is essential for delivering ultra-reliable low latency communications (URLLC) by bringing compute and network functions closer to users.”
https://www.cablinginstall.com/testing/article/14280490/exfo-tier-1-us-operator-taps-exfo-for-5g-network-testing-from-core-to-edge-to-last-mile?utm_source=CIM+Cabling+News&utm_medium=email&utm_campaign=CPS220729030&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
The test, monitoring and analytics experts at EXFO recently announced that a Tier 1 U.S. mobile network operator (MNO) has chosen to deploy EXFO’s Nova Active testing capabilities across its 5G network, from core to edge to last mile, to better enable ultra-fast, ultra-reliable connections for the operator’s customers.
According to an April press release, results of synthetic network tests from the Nova Active platform will be paired with EXFO’s Nova SensAI software—already deployed with the MNO—to diagnose customer-impacting performance issues in real time and to reduce troubleshooting mean time to repair (MTTR), according to the test equipment provider.

Plan for the future with 5G, mobile edge computing
https://www.controleng.com/articles/plan-for-the-future-with-5g-mobile-edge-computing/?oly_enc_id=0462E3054934E2U
With the help of 5G and mobile edge computing, business owners, manufacturing facility managers and control engineers are experiencing the benefits of transforming traditional, manual processes into automated, efficient technological solutions.
Edge Computing Insights
5G and mobile edge computing enable key business applications and supports near real-time operational insights, which can help users optimize data collection and storage to increase productivity.
With 5G and mobile edge computing, manufacturers can operate separate smart assembly lines from one virtualized location and can reconfigure as needed, which increases their flexibility.
5G in manufacturing is already becoming a reality and companies that get ahead of the curve will be well-positioned for the future. Like automation, it is becoming a necessity, particularly due to the mass labor shortages in the industry.
Massive transformation is expected to change the way manufacturing facilities operate with the help of 5G in the coming years as manufacturers consider how leveraging technology and adapting to data-driven systems will be key to staying ahead of their competitive set. According to a recent study conducted by the Manufacturing Institute, 91% of manufacturers believe 5G connectivity will be important to the future of their business.
Factories going digital understand the hassle that comes with major facility changes. However, with the help of 5G and mobile edge computing, business owners, manufacturing facility managers and control engineers are beginning to experience the benefits of transforming traditional, manual processes into automated, efficient technological solutions.
5G and mobile edge computing enable key business applications to run on a network close to (if not located on) a work site, which decreases lag time and supports near real-time operational insights, which can help users optimize data collection and storage to increase productivity.
Location accuracy enabled by 5G, mobile edge computing
Beyond streamlining processes, manufacturing facilities can expect to see more accurate production and fewer disruptions. Present-day manufacturers often suffer from Wi-Fi signal interference, especially in highly metallic environments. Low location accuracy and connectivity issues hinder the facility manager and control engineer’s ability to accurately track location. This is needed to keep operations running smoothly and ensure smart machinery like autonomous mobile robots (AMRs) and automated forklifts are where they need to be.
Location accuracy enabled by 5G and mobile edge computing should allow manufacturers to detect where near misses with a forklift and a worker, or a robot and a worker, occur. 5G is currently being tested indoors in these highly metallic environments so facility managers and control engineers will be able to accurately locate and operate AI and ML tools in near-real time from a remote location. 5G and mobile edge computing can enable near real-time interaction and a closed-loop control of AMRs and other ML tools, delivering reliability and safe production services within the factory.

Telia tuo viipalointitekniikat 5G-SA-kotiyhteyksiin
https://www.uusiteknologia.fi/2022/09/09/telia-tuo-viipalointitekniikat-5g-sa-kotiyhteyksiin/
Telia tuo itsenäiset standalone-yhteydet kodin kiinteisiin 5G-liittymiin ensimmäisenä maailmassa ja päivittää samalla verkon viipaloinnin Nokian kanssa 5G-verkkoonsa. Telia parantaa 5G-verkon kuuluvuutta myös ottamalla käyttöön 5G-taajuuksien yhdistelyn.
5G-taajuuksien yhdistely parantaa kuuluvuutta erityisesti sisätiloissa ja kuuluvuuden reuna-alueilla, ja sitä laajennetaan, kun nyt 3G-verkon käytössä olevat taajuudet vapautuvat käyttöön.
Itsenäisen Standalone 5G-verkon kaupallinen käyttö on myös askel kohti 5G:n tulevaisuuden lupausten lunastamista. Itsenäisen 5G-verkon etuna on parempi energiatehokkuus, entistä alhaisempi viive ja vakaampi yhteys esimerkiksi sisätiloissa.
”Otimme itsenäisen 5G:n tuotantoon ensimmäisten joukossa Euroopassa, ja käyttäjien kannustavan palautteen myötä tuomme tämän teknologian kaupallisiin palveluihimme”, sanoo Telia Finlandin teknologiajohtaja Jari Collin.
Nokian ohjelmistopäivityksen ansiosta verkkoa voidaan nyt viipaloida eri asiakasryhmien tarpeisiin, eli verkossa voidaan jatkossa huomioida asiakkaiden yksilöllisiä nopeuden, viiveen tai tiedonsiirron laadun tarpeita. Itsenäinen SA 5G-verkko tuodaan ensimmäisenä Telian 100 Mbit/s:n kodin kiinteisiin 5G-liittymiin. Seuraavaksi viipalointiominaisuus tuotteistetaan muihinkin kodin 5G-liittymiin.
Taustaa: Telia otti itsenäisen 5G-ydinverkon tuotantokäyttöön jo viim e vuoden marraskuussa yhtenä ensimmäisistä operaattoreista Euroopassa. Alkuvuodesta standalone-teknologia oli käytössä jo kymmenissä paikoissa ympäri Suomen, ja kesäkuun alussa Telia otti itsenäisen 5G-verkon käyttöön Telian koko 5G-verkossa 3,5 GHz taajuusalueella.

OTA vs. Coaxial Interconnect Testing
https://www.jfwindustries.com/application-notes/new-white-paper-compares-ota-vs-coaxial-interconnect-testing/
JFW’s newest white paper explores the advantages and disadvantages of both Over-The-Air testing and more traditional testing methods using coaxial interconnects in 5G wireless laboratories.
Head-to-head coaxial interconnect vs OTA testing for 5G
https://www.jfwindustries.com/wp-content/uploads/2021/03/JFW_CoaxVsOTAtesting_TechBrief_FINAL.pdf
Without question, the rise of 5G has changed the landscape of wireless testing. One of the biggest changes is the
ability of test engineers to perform over-the-air (OTA) testing without connecting anything or having a special setup.
This is something that was not historically possible with past generations of wireless devices, as a result of FCC
regulation and spectrum licensing law. OTA testing has the potential to revolutionize wireless device testing and
enable innovative testing of advanced antenna systems (AAS) and antenna array technology.
However, there are several critical disadvantages of OTA testing that limit its applicability to all 5G sub-6 GHz (5G FR1)
and millimeter-wave (5G FR2) device testing. One such consideration is the variability of OTA testing, which appears
to be many times that of traditional coaxial transmission line test methods. Equally, there are limitations to coaxial
test methods addressing the test needs of the latest beamforming and multi-input multi-output (MIMO) antenna
technology. It is becoming increasingly clear moving forward that successful testing of 5G wireless technology must
include OTA and RF over coax testing to tackle the pre-existing and emerging challenges of 5G device performance
and conformance testing. What is most important is to understand the advantages and disadvantages of both to
determine where and when to use each test approach

Wireless communications have become increasingly critical to communications for industrial automation. Now, fifth-generation (5G) cellular communication is widely heralded as the key wireless technology to advance the fourth industrial revolution — Industry 4.0 or the Industrial Internet of Things (IIoT). Some sources even suggest that 5G will be key to making consumer and other non-industrial IoT installations ubiquitous in large part because 5G facilitates the connection of staggering numbers of devices, wherever those devices happen to be located.

Sept. 15, 2022
IBM aspires to integrate Keysight solutions with its Cloud Pak for Network Automation in IBM’s Center of Excellence.
https://www.electronicdesign.com/technologies/test-measurement/article/21250756/microwaves-rf-keysight-and-ibm-ink-deal-to-accelerate-european-open-ran-deployments
As Open RAN seeks to gain a foothold in the telephony infrastructure arena, it’ll need boosts from big players. To that end, Keysight Technologies has signed a memorandum of understanding (MoU) with IBM to pursue accelerating open radio-access-network (RAN) deployments in Europe.
IBM plans to use Keysight Open Radio Architect (KORA) solutions in the company’s Open RAN center of excellence (CoE), established in 2021, to help mobile operators drive innovation to meet the standards defined by the O-RAN Alliance. IBM intends to integrate Keysight’s software-centric open RAN test, measurement, and emulation tools with IBM’s Cloud Pak for Network Automation, an AI-powered telco cloud platform that enables the automation of network operations.
Kalyan Sundhar, vice president and general manager for Keysight’s wireless network access business, said, “The integration of Keysight’s open RAN test solutions with IBM’s Cloud Pak for Network Automation will help service providers in automating applications that are critical to delivering a wide range of connectivity services.”
Based in Madrid, Spain, IBM’s CoE enables communications service providers (CSPs) to deploy IBM solutions in their laboratory environments or live networks to support private and industrial applications.
Keysight’s open RAN solutions will support IBM in demonstrating O-RAN solutions to CSPs seeking partnerships. These open RAN solutions will enable vendors to verify conformance, interoperability, performance, and security, resulting in the deployment of fully interoperable RAN equipment. IBM’s CoE intends to use Keysight’s radio unit simulator, RuSIM, to validate O-RAN distributed units (O-DUs); CoreSIM, to verify the performance of open RAN equipment; and Nemo Wireless Network Solutions to optimize and monitor wireless network

How 5G Has Changed Engineering Design
Opinion
https://www.eetimes.com/how-5g-has-changed-engineering-design/?utm_source=newsletter&utm_campaign=link&utm_medium=EDNConsumerElectronics-20220914&oly_enc_id=2359J2998023G8W
The past decade has seen unprecedented advances in technology, including the widespread use of smartphones, billions of internet-of-things devices being deployed in all areas of industry, the introduction of Industry 4.0, and the rise of edge computing. But this technological growth is not slowing down. While this is advantageous in many ways, it is also straining infrastructure. It is clear that next-generation technology will not be able to function unless this infrastructure issue is met head on.
One particularly troublesome factor is the introduction of cloud computing, because it removes the need for individual devices to process their own data. Although this dramatically simplifies their design and lowers their cost, it also requires higher bandwidth and lower latency.
Edge computing is one solution that can alleviate some of the issues that cloud computing faces. However, because edge computing devices will likely be in a local network, bandwidth restrictions can see performance degradation for other internet-connected devices connected to the same network.
Numerous network technologies exist, with each having its own advantages and disadvantages. The major network technologies in widespread use include Wi-Fi, cellular, long-range (LoRa), and cables (that is, fiber).
Wi-Fi provides an excellent balance between speed, latency, and cost, which is why it has dominated the home wireless market. But the higher frequencies that 5 GHz and 6 GHz use reduce their effective range.
Cellular networks like 4G have been developed with mobile technologies in mind, and as such, they offer excellent characteristics with range and device support. However, they are impractical for real-time IoT applications. They have large download speeds but suffer from latency due to the length of time waiting for a time slot.
LoRa radio is a network technology that is gaining popularity in remote IoT applications due to its low energy requirements and long-range capabilities (over 15 km in some cases). To reduce energy consumption, LoRa has an extremely small bandwidth and is only ideal for sending bytes of data. (It is not suitable for live-streaming video.) As such, LoRa is commonly found in remote industrial sites, such as oil pipelines, farms monitoring large amounts of land, and environmental sensors identifying potential forest fire risks.
Optical fiber, also called fiber, is the ultimate solution when it comes to speed and latency, because using a physical connection removes the need for a high-energy antenna, sensitive receivers, and complex network hardware. However, the physical nature of cables means that only devices physically attached to the cable can utilize the network.
What 5G offers
Unlike its predecessor, 5G has been designed with connectivity in mind, with a key focus on IoT devices, edge computing, and cloud computing. As such, its primary aim is to give customers higher speeds, lower latency, and infrastructure that can improve network services.
5G utilizes higher frequencies in the microwave region, which increases its bandwidth (reaching as high as 20 Gbps) and utilizes multiple nonoverlapping channel frequencies. Additionally, the use of MIMO antenna and beamforming further reduces the interference between devices operating on the same channel.
5G also significantly reduces the latency of connections using numerous techniques, including network slicing, nonfixed time slots, and local edge computing services. Network slicing allows 5G networks to create individual channels that minimize the number of simultaneous devices using any one channel, while the introduction of nonfixed time slots enables 5G devices to transmit data whenever they need to.
Finally, in 5G networks, data-heavy cloud services can be located closer to users, which means connected clients can access resources much faster. (Instead of going from device to cell tower to internet and back again, clients can directly access the cell tower and get the data they need.)
Future applications
While 5G is still in its infancy, numerous applications can seriously benefit from the high-bandwidth, low-latency capabilities offered.
One such example would be vehicle-to-everything (V2X). A major challenge that automotive manufacturers face is the development of autonomous driving and collision avoidance. Current solutions must operate independently, meaning they often rely on numerous imaging technologies, including radar and LiDAR. While this is beneficial in handling unusual situations, it still sees limited response times and introduces unknowns.
However, V2X proposes a solution whereby all devices (including all vehicles, pedestrians, road signs, and traffic control systems) report critical data such as position, direction, and speed. Using 5G network data, vehicles on the road can predict collision risks well in advance while also warning pedestrians and other vehicles of their own position, speed, and direction. As such, V2X presents numerous safety and traffic management opportunities thanks to the low latency and large device support that 5G offers.
Industrial sites are another promising application for private 5G networks, whereby operators create and manage their own 5G networks. Many industrial processes often rely on real-time data obtained from machinery, which is why industrial systems have historically struggled to operate on common LAN networks. The large number of simultaneous connections combined with the use of autonomous delivery systems that can move throughout a plant also make technologies such as Wi-Fi unsuitable.
The ability for 5G network devices to roam between access points without losing connection and offer low latencies makes 5G ideal for use in industrial sites. Not only can such networks support the high device count, but traffic can be prioritized depending on its importance. (Better latency can be provided to real-time data packets.) Furthermore, the use of edge-computing services located at individual access points decreases latency while reducing the stress placed on the larger network.
The introduction of IoT devices has also opened new possibilities in city management and planning, sparking a new sector of IoT: smart cities. Arguably the two largest challenges that city management faces involve traffic management and pollution.
5G networks are perfect for the development of smart cities, not just because of their ability to handle thousands of devices and offer large bandwidths but because of their ability to run virtual networks that can deploy strong security practices that remove the need for passwords and API keys and favor physical device authentication.
5G offers engineers exciting new possibilities thanks to its increased bandwidth, improved latency, and ability to support edge computing. Furthermore, the ability to create private 5G networks opens new opportunities for businesses and manufacturers. Finally, the ability to run services at the edge can improve cloud-based applications for millions of customers.

US Agencies Publish Security Guidance on Implementing Open RAN Architecture
https://www.securityweek.com/us-agencies-publish-security-guidance-implementing-open-ran-architecture
The Cybersecurity and Infrastructure Security Agency (CISA) and the National Security Agency (NSA) have published guidance on implementing an Open Radio Access Network (RAN) architecture.
A general-purpose document titled Open Radio Access Network Security Considerations, the guidance is based on current knowledge and recommended practices and should apply to a variety of industries.
“Open RAN is the industry term for the evolution of traditional RAN architecture to open interoperable interfaces, virtualization, and big data and AI-enabled intelligence,” the document reads.
An Open RAN architecture, CISA and the NSA explain, opens the door to cloudification and virtualization, while promoting ‘increased competition, vendor diversity, and innovation’ by creating a multi-vendor ecosystem.
Open RAN can increase resiliency and flexibility in telecommunications networks through the adoption of ‘best-of-breed’ solutions from multiple vendors and also takes advantage of the security features of 5G, while offering increased transparency to help identify and address issues in real-time, the document notes.
“The deployment of Open RAN introduces new security considerations for mobile network operators (MNO). By nature, an open ecosystem that involves a disaggregated multi-vendor environment requires specific focus on changes to the threat surface area at the interfaces between technologies integrated via the architecture,” CISA and the NSA note.

Nova Labs and T-Mobile sign a five-year deal to launch Helium Mobile, a 5G MVNO service for smartphones that combines coverage from the two companies’ networks
Helium Founders, T-Mobile Launch Crypto-Powered 5G Mobile Service
https://decrypt.co/110111/helium-t-mobile-crypto-5g-mobile-service
Helium Mobile will tap both the decentralized 5G network and T-Mobile’s service while also offering crypto rewards to users.
In brief
Nova Labs and T-Mobile have partnered to launch Helium Mobile, a 5G wireless service for smartphones.
It will use Helium’s decentralized, crypto-powered 5G network as well as T-Mobile’s network, and switch between the two as needed.
Crypto-fueled wireless network Helium will soon be able to introduce its mobile 5G vision to many more users. Today, Helium network founder Nova Labs announced that it has partnered with T-Mobile to create a new 5G wireless service called Helium Mobile.
Helium Mobile will be a mobile virtual network operator (MVNO) service and will tap both the T-Mobile and Helium networks for customers in the United States. Set to launch in the first quarter of 2023, the service will rely both on T-Mobile’s nationwide 5G network and Helium’s user-operated 5G nodes.
By combining networks and switching between the two as needed, Nova Labs says the service will offer two significant economic differentiators from traditional services: plans will start at just $5 per month, and users can also optionally earn crypto token rewards for sharing data.
Boris Renski, co-founder and CEO of Nova Labs-owned firmware and hardware maker FreedomFi, said that using Helium’s decentralized 5G network—which includes more than 4,500 active user-operated nodes at present—means that Nova doesn’t have to invest in capital expenditures to build out infrastructure.
“That allows us to build a cellular network with absolutely disruptive economics,” he told Decrypt.
On top of that, Helium Mobile will allow users to opt into receiving the network’s MOBILE token rewards in exchange for providing anonymized data about their network usage. Renski said that the service will treat such users as contributors, as the data will be used to monitor network quality and availability as it scales—but it’s purely optional.
Helium is a network of decentralized wireless hotspots that incentivizes users with crypto tokens for running a node and supporting the network. The initial Helium network, focused on powering Internet of Things (IoT) devices like sensors and trackers, has more than 950,000 node operators at present.
The 5G network is newer and has far fewer users so far, as the 5G hardware is also currently much more expensive than the nodes that support the original IoT network. I
How it works
Helium’s own 5G network will be the preferred network for Helium Mobile when coverage is available, Renski said. It’s a relatively small network at present, but it’s growing: Helium’s second network has taken shape since launching MOBILE token rewards, with over 1,700 new user nodes activated in the last 30 days—and Renski said the pace is increasing.
Initially, voice calls will take place entirely on T-Mobile’s network, while data transfers will use service provided by node operators in the decentralized network where available. Otherwise, it automatically falls back to T-Mobile’s network. As Helium’s network expands, more of the load will be moved off of T-Mobile’s infrastructure.
There’s still work to be done in the months ahead to make the automated process of switching more seamless, Renski told Decrypt. Initially, users may encounter small delays as their smartphone switches between one network and the other
“I would say that we have traveled maybe halfway on this journey at this point,” said Renski of refining the technical infrastructure. “But we still have some way to go to make sure that all the users have a smooth user experience.”
Additionally, Nova Labs is working with smartphone makers to design phones that are specially designed to accommodate seamless switching. Users will be able to bring their own phone, as well, but a press release suggests that the Helium-certified phones will be “more efficient” at validating network coverage and thus can earn more MOBILE token rewards.
The Helium Mobile news comes following the launch of a proposal to move the network from its own custom blockchain to Solana, a rising blockchain platform for apps, DeFi, and NFTs.

5G-yhteydet kaksinkertaistuvat joka vuosi
https://etn.fi/index.php/13-news/14037-5g-yhteydet-kaksinkertaistuvat-joka-vuosi
5G-yhteyksien määrä kasvoi 813 miljoonaan vuoden toisella neljänneksellä. 5G Americasin mukaan kasvua tuli 112 prosenttia vuodetakaisesta. Jatkossakin sama tahti jatkuu: 5G-yhteyksien määrä kaksinkertaistuu joka vuosi.
Vuoden 2027 loppuun mennessä yhteyksiä olisi näin ollen 5,9 miljardia. Globaalien 5G-yhteyksien kaksinkertaistuminen seuraa mobiilidatan käyttöä, joka esimerkiksi Ericssonin mukaan myös kaksinkertaistuu vuosittain.
Kesäkuun lopulla Pohjois-Amerikassa oli yhteensä 99 miljoonaa 5G-käyttäjää ja 502 miljoonaa LTE-käyttäjää. Kolmen kuukauden aikana 5G-verkkoon liittyi 17 miljoonaa uutta käyttäjää. Nyt joka kolmannella amerikkalaisella on käytössään 5G-älypuhelin. Vuoden loppuun mennessä käyttäjien määrä kasvaa 137 miljoonaan.
Koko maailmassa 5G-verkkoja on tällä hetkellä käytössä 233.

ORAN-radion tehonkulutus putoaa kymmenesosaan
https://etn.fi/index.php/13-news/14043-oran-radion-tehonkulutus-putoaa-kymmenesosaan
Open RAN on avoin radioverkkoarkkitehtuuri, joka mahdollistaa eri valmistajien komponenttien käyttämisen radioverkossa. Tähän asti yksi ORAN-tukiasemien ongelmista on ollut iso tehonkulutus, joka on suora seuraus FPGA-piirien käytöstä.
Nyt mobiiliverkkojen DSP-piireistä tunnettu CEVA on esitellyt markkinoiden ensimmäisen kantataajuusprosessorin IP:n avoimiin 5G-radioverkkoihin. IP:n avulla kantataajuusprosessointi voidaan toteuttaa ASIC-tyyppisesti, mikä laskee tehonkulutuksen jopa kymmenesosaan.
CEVAn P:tä voidaan käyttää niin ORAN-verkkojen hajautetuissa yksiköissä (DU) kuin etäradioyksiköissä (RRU) eli aktiiviantenneissa. Ne sopivat toteutuksiin pienestä solusta massiivisiin mMIMO-yhteyksiin.
5G-tukiasemien ja ASIC-radiopiirien kasvavia markkinoita ruokkii digitaalinen muutos, joka vaatii jatkuvasti suurempaa matkapuhelinkaistanleveyttä pienemmällä viiveellä. Äskettäin Open RAN -aloitteen ja mMIMO:n ohjaama verkkojen, komponenttien ja valmistajien hajautuminen on kiinnittänyt piirinvalmistajien matkapuhelintukiasemien markkinoihin. Esimerkiksi ABI Research ennustaa, että 5G-verkkojen Open RAN -tukiasemien toimitukset kasvavan 17 prosentin vauhtia vuosina 2022–2027.

Qualcomm astuu Nokian varpaille tukiasemissa

Qualcomm on ryhtynyt toimittamaan näytteitä uusia tukiasemien 5G-modeemikortteja. X100-kortti ja QRU100-alijärjestelmä on tarkoitettu kiihdyttämään avoimien Open RAN -verkkojen kaupallista. Kyse on täysin uudesta piirisarjasta, mutta sen myötä Qualcomm astuu ainakin kevyesti Nokian varpaille makrosoluverkoissa.
Qualcommilla on aiemminkin ollut tukiasemien komponentteja tarjolla, mutta ne ovat olleet lähinnä pieniin pikosoluihin. Operaattorien makroverkkoihin se ei ole aiemmin koskenut. Open RAN muuttaa tätä kuvaa.
Open RAN on arkkitehtuuri, jossa operaattori voi valita radioverkon eri komponentteja eri valmistajilta. Open RAN Alliance on standardoinut liitännät eri osien välillä niin, että ne toimivat saumattomasti yhteen. Näin siis periaatteessa. Tällä hetkellä Open RANin osuus 5G-markkinoista on äärimmäisen pieni, joten Qualcommin Nokialle esittämä haaste on aika köykäinen.

Nokia ilmoitti tänään laajentavansa markkinoiden johtavaa valikoimaansa kestäviä käyttäjälaitteita käytettäväksi vaarallisissa, syttyvissä, räjähdysalttiissa ja pölyisissä ympäristöissä. Yhtiö esittelee HMD Globalin luomia parannettuja versioita Nokia Industrial 5G FieldRouterista ja Nokia XR20 -älypuhelimesta 4.9G- ja 5G-verkkoihin.
Nokian Industrial 5G -kenttäreitittimet ratkaisevat ongelman vanhojen teollisuuslaitteiden ja ajoneuvojen yhdistämisestä yksityiseen langattomaan verkkoon, jotta yritykset voivat hyötyä Teollisuus 4.0:n käyttötapauksista, kuten itsenäisistä toiminnoista kaivoksissa, satamissa ja tehtaissa. Nyt öljy- ja kaasuyhtiöt voivat käyttää teollisia kenttäreitittimiä autonomisten ajoneuvojen yhdistämiseen vaarallisilla alueilla tai kerätä ympäristö- ja muuta dataa koneista, jotka on yhdistetty kenttäreitittimillä yksityisen langattoman verkon kautta.
Osana Nokian teollisuusratkaisua HMD Globalin valmistamasta XR20-älypuhelimesta on kehitetty teollisuusversio. Laitetta on paranneltu vastaamaan vaarallisissa ympäristöissä toimimisen vaatimuksia. Älypuhelimissa olevien sovellusten, kuten Nokia Team Comms tai Group Communications, avulla työntekijät voivat olla vuorovaikutuksessa pikayhteyden ja videon avulla. Nokia Industrial 5G -kenttäreitittimet ja Nokia XR20 Industrial Edition -puhelimet ovat ATEX- ja IECEx-sertifioituja, ja Nokia XR20 Industrial Edition on myös NEC500- ja UL-sertifioitu täyttämään suojausvaatimukset eri puolilla maailmaa.

Ericsson: Open RAN sisältää edelleen ongelmia
https://etn.fi/index.php/13-news/14092-ericsson-open-ran-sisaeltaeae-edelleen-ongelmia
Ericssonin Pohjois-Amerikan teknologiajohtaja Mike Murphy kertoo Mobile World Liven haastattelussa, ettei avoimella 5G-tekniikalla eli Open RANilla päästä merkittäviin parannuksiin verkkojen suorituskyvyssä tai kustannuksissa. – Itse asiassa eri Open RAN- ja klassisten verkkojen välillä on vain kasvanut, Murphy sanoo.
Tomi Engdahl says:
https://etn.fi/index.php/13-news/14092-ericsson-open-ran-sisaeltaeae-edelleen-ongelmia
Avoimia radioverkkoja perustellaan usein sillä, että verkon eri osien rakentaminen eri valmistajien laitteista tuo saman kapasiteetin edullisemmin kustannuksin, kuin ns. perinteisissä verkoissa, joissa kaikki verkon osat tulee yhdeltä toimittajalta. Open RAN voidaan karkeasti nähdä varsin amerikkalaisena projektina, jossa markkinoita ei haluta antaa vain Nokian, Ericssonin ja Samsungin temmellyskentäksi.
Miksi Open RAN sitten ei ole edullisempi? Murphyn mukaan syitä on useita. Esimerkiksi hän nostaa sen, että IT-järjestelmien – joihin Open RAN-verkkojen laskenta perustuu – toimintalämpötila on kapeampi kuin perinteisissä tietoliikennelaitteissa, joten ehkäpä Open RAN -tukiasemia joudutaan lisäjäähdyttämään. Tämä tekee verkon toteuttamisesta kalliimpaa.
Yksi ongelma on FPGA-piirien laaja käyttö Open RAN -toteutuksissa. FPGA on kallis ja paljon tehoa kuluttava piiritekniikka, mistä Nokiakin kärsi räätälöityjen ReefShark-piirien myöhästyessä. ASIC-toteutus on aina kustannustehokkaampi ratkaisu suuremmissa volyymeissä ja Open RAN -toteutuksiin on vasta viime aikoina alkanut tulla mitään ASIC-piirejä muistuttavia ratkaisuja.
Moni kuitenkin uskoo avoimiin verkkoihin. Esimerkiksi tutkimuslaitos Dell´Oro arvioi, että vuoteen 2026 mennessä 15 prosenttia RAN-verkoista perustuisi Open RAN -määrityksiin. Aasiassa osuus voisi olla jopa 40 prosenttia.
Toinen markkinaa muuttava tekniikka on virtualisoitu RAN eli vRAN, jossa verkon toimintoja ja laskentaa viedään pilveen. sen osuuden Dell´Oro arvioi kasvavan 5-10 prosenttiin RAN-markkinoista vuoteen 2026 mennessä.

Verizon’s (and others’) 5G: underwhelming is putting It mildly
https://www.edn.com/verizons-and-others-5g-underwhelming-is-putting-it-mildly/
Curb your enthusiasm, however, because the carriers have other tricks up their sleeves. Once again, for example, a reminder that if your AT&T-locked phone says it’s on a “5G Evolution” network, that’s not real 5G. Also as already mentioned, Verizon only supports 5G UW (mmWave) on carrier-locked versions of 5G-capable Google Pixel phones, and those phones are sold at a premium to the pricing of unlocked equivalents. Verizon (and partner Google) also refuse to enable C-band support on legacy 5G phones, even if those phones’ wireless subsystems support the relevant mid-band frequency ranges…and I’d wager that any C-band support will, like mmWave support, only come on carrier-locked phones. And AT&T is doing the same thing, breaking previous promises in the process. Sigh.

The 5G Sun is Rising
https://teltonika-networks.com/resources/articles-archive/the-5g-sun-is-rising/
5G.
It can be difficult to encapsulate the meaning hiding beneath the surface of this one number and one letter standing casually next to each other. It is significantly more than just 4G+1, but how much, really? Is it just a matter of speed with higher numbers, or does it open IoT doors that were previously closed? These are but the tip of the iceberg of the questions 5G raises. And as the 5G sun is rising, it’s a good time to answer some of them and gain a better understanding of things to come. Hold on to your routers, because we’re in for something big.
5 is the New 4
One of the first verbs that came to be associated with using the internet is surfing. If a sea is a network of water droplets, the internet is a network of data bits. Like surfers in the connectivity sea, we’ve been riding the 4G wave for a while now; long enough to know how far can we push our limits with it. 5G (G for generation), is at the most basic level a bigger wave that enables better, cooler surfing tricks.
At its core, 5G uses a 5G New Radio (NR) interface and is based on orthogonal frequency-division multiplexing (OFDM), which is a method of modulating digital signals in different channels to minimize interference. It also utilizes mmWave, sub-6 GHz, and wider bandwidth than 4G’s, and can cover frequencies up to 39GHz but is expected to utilize carrier frequencies up to 71 GHz in the future. All of this results in a faster network with greater capacity and lower latency.
G for Growth
The economic prospects of 5G are just as optimistic. Its estimated global market share was approximately $64.5 billion in 2021 and is expected to reach $1.87 trillion by 2030, yielding a compound annual growth rate (CAGR) of 44.63%. In contrast, 4G’s global market share was estimated at $313.3 billion in 2020 and is expected to reach $2.5 trillion by 2027, with a CAGR of 34.7%.
What this means is that 4G isn’t going away anytime soon, and will continue to grow, but with 5G catching up at a greater pace in the long run.
Growing market share isn’t the only source of optimistic numbers 5G brings to the table. It’s also expected to create 22.8 million jobs by 2035 and raise global GDP by 10.8%, with manufacturing, healthcare, and agriculture having a 20-30% expected productivity growth rate. 5G-enabled intelligent transportation is estimated to reduce traffic and its pollution by 15%, and reduce CO2 emissions from mobile networks by 50% over the next decade. The future, painted with 5G colors, appears to be bright and green!

The 5G Sun is Rising
Okay, so 5G is the shiny new toy on the shelf. Does it actually matter for the IIoT world?
Yes, and quite a lot.
Maximizing speed and reliability while minimizing latency allows for more than just doing the same but better – it opens up new opportunities that can only exist when network precision reaches a critical threshold. One example is predictive maintenance, which means fixing things before they get a chance to go wrong.
Another example is digital twins – dynamic, real-time digital replicas or physical systems. These allow for a brand-new world of hypothetical testing and software updating that cannot be achieved with 4G. Digital twins are the new standard of the aerospace industry but will become a standard for many more moving forward.
So when will Teltonika Networks have its first new 5G-supported devices? Soon. Very soon.

GPS-Less Device Localization with RMS
https://teltonika-networks.com/resources/articles-archive/gps-less-device-localization-with-rms/
As it happens, the popularity of cellular internet enables our Remote Management System (RMS) to approximate the location of any cellular router or gateway with an active mobile connection – even if the device doesn’t have any GPS capabilities.
How does that work?
The device may not have a built-in GPS, but the cell tower that provides it with cellular connectivity is still in a fixed location. Once a day, RMS checks the cell ID to which the device is connected and approximates where on the map the device is located in relation to that cell tower. You can find it on your device page by clicking on Device Map.

Approaching an Inflection Point in 5G Device Testing

The continually evolving 5G has unique needs, so companies can’t rely on initial R&D general-purpose test equipment, or radio communication testers designed for 4G/LTE. This article covers RF and signaling tests, and reviews the latest test requirements.
What you’ll learn:
Evolution of cellular and device testing from 4G LTE to 5G cellular and device testing.
Current 5G application test requirements.
The 5G wireless technology standard is one of the fastest and most robust technologies available to consumers. Slowly replacing 4G around the world, 5G is delivering higher peak data speeds, low latency, and better bandwidth with greater uniformity.
While 4G was designed for cellular phones, 5G boasts the flexibility to connect machines, objects, and devices—better representing the way we use connected devices today and replacing the need for more specialized technologies. Beyond accelerating global technology innovation, 5G introduces use cases in industrial IoT (i.e., machine-to-machine communications) and ultra-low latency (e.g., remote medical operations).
The evolution of 5G depends on the development of two other major technologies. The first, enhanced mobile broadband (eMBB), supports peak data rates for massive amounts of users on the move; it extends services enabled by 4G LTE to meet expanding technological needs more efficiently.
The second, ultra-reliable low-latency communications (URLLC), is a subset of the 5G network architecture that focuses on efficient data-transfer scheduling, shorter transmissions, and enabling overlapping transmissions. The network needs low-latency capabilities for emerging applications in virtual reality (VR) and augmented reality (AR) among others, and URLCC offers that robustness to accommodate.
Generational Change in Communication Technologies
When new mobile wireless technologies emerge, companies opt to invest in high-performance, general-purpose test equipment for early research and development. Then, as standards form, they migrate to lower-cost, purpose-built equipment to test accordingly. As far back as 2019, companies were setting themselves up for early-release 5G by purchasing general-purpose equipment, but many decided to stretch their 4G testing technology instead.
4G LTE and early 5G equipment have accommodated rapid expansion in global communications. However, the onslaught of low-latency applications (e.g., gaming, real-time streaming, video) is encouraging more and more providers (e.g., AT&T, Verizon, etc.) to upgrade to the standalone 5G core network.
Today, companies face the inflection point that inevitably arises when wireless technologies advance. Just as 4G evolved into early-release 5G, with new network architectures, 5G is going to start looking like early-release 6G. Existing equipment that might have been stretched from 4G isn’t going to cover the full spectrum of 5G testing.
Cellular and Device Testing Today
5G is unique in its requirements, so companies can’t rely on general-purpose test equipment that was used early on in 5G research and development, or radio communication testers that were initially designed for 4G/LTE. With new applications added in every release, it continues to evolve.
So, in addition to RF measurements and signaling tests, here are a few of the unique application testing requirements we see today, that will continue to evolve as we move toward 6G.
IP throughput testing: Complex test scenarios help designers meet data rate expectations. Maximum throughput testing in 5G is more challenging today because of factors like new radio resources and more bandwidth.
Audio and video quality: Voice over new radio (VoNR) audio quality and audio performance tests are required for maximum voice performance and better user experience. Voice-over-5G test systems must fulfill complex requirements and support codecs for VoNR, voice over LTE (VoLTE), and beyond.
Battery life: With high-performance, high-throughput applications, 5G brings significant power-consumption challenges; yet users still expect extended battery life. Meeting those expectations requires analyzing battery consumption for different scenarios and use cases.
IP security: Data and IP security are paramount in today’s highly connected world. Particularly for devices that manage or store sensitive data, it’s important for developers to focus on testing and identifying weak spots in their applications and mobile designs that might jeopardize IP connection security and/or fail to meet regulatory compliance requirements.
As the foundation for 5G becomes more stable and more 3GPP features are adopted and commercialized, there’s a greater need for purpose-built test equipment that’s able to handle any new standard, capability, or application introduced by 5G.

Reaaliaikainen 5G digitoi tehtaat
https://etn.fi/index.php/tekniset-artikkelit/14191-reaaliaikainen-5g-digitoi-tehtaat
Reaaliaikaisuuteen yltävä 5G-viestintä ja vankat reunapalvelimet kiihdyttävät teollisuuden digitalisointia. Uudet COM-HPC-standardin mukaiset palvelinmoduulit ruokkivat tätä kehitystä poikkeuksellisen kestävän rakenteensa ansiosta. Se mahdollistaa käytön myös ilmastoitujen datakeskusten ulkopuolella tehdassalien ankarissa tuotanto-oloissa ja haastavissa ulkoympäristöissä.
Teollisuudessa sovellettavan esineiden internetin (IIoT) tavoitteena on luoda digitaalinen hermojärjestelmä, joka yhdistää kaikki fyysiset kohteet kuten tuotantotilat, koneet ja kulkuneuvot digitaaliseen ohjaukseen, resurssien suunnitteluun ja logistiikan prosesseihin. Järjestelmä on suunniteltu mahdollistamaan entistä ketterämmin etenevä tavaroiden virta, joka mukautuu kysyntään, sekä reaaliaikainen hallinta, joka syntyy JIT-logistiikan (just-in-time) tarpeesta.
Tämä edellyttää tuotantosoluissa yhteistyötä tekevien robottien ja omatoimisesti liikkuvien ajoneuvojen jatkuvaa kommunikointia toistensa kanssa. Anturien ja konenäköjärjestelmien on siksi kerättävä kaiken tyyppistä dataa, joka sitten analysoidaan käyttäen paikallista reaaliaikaista infrastruktuuria ja tekoälyä hyödyntäviä reunapalvelimia.
