5G? IoT? Fiber Deep? 600G? We Are ready for networking at 2019!
For years we have all been talking about the emergence of 5G services, the Internet of Things (IoT) and the new high-capacity, low-latency network architectures that will be needed to support the resulting onslaught of bandwidth. Higher-speed data rates are critical to electronic evolution and revolution.
Here are some of my collection of newest trends and predictions for year 2018. have picked and mixed here quotations from many articles (linked to source) with some of my own additions to make this posting.
5G: The most newsworthy stories in wireless today are all about 5G. In 2019, we enter a cautious, early-adoption phase of this next generation of wireless technology. 2019 will be the year when we see the first commercial networks turning on and first handsets arriving in the market. Only a small number of users will get a first taste of 5G in specific geographic locations, using specific applications, none of which are ubiquitous or cost-optimized. For more details read my 5G trends for 2019 posting.
Deep fiber: Deep deployment of fiber optics into national network infrastructure might not be as glamorous as the eagerly anticipated launch of fifth-generation mobile networks (5G); however, it is just as important—maybe even more important. Wired broadband access supports as much as 90 percent of all internet traffic even though the majority of traffic ultimately terminates on a wireless device. Wireline and wireless networks are driving new architectures to support the move from 4G LTE to 5G infrastructure. In fact, 5G relies heavily on fiber infrastructure. Service providers in the access market are talking about the evolution of their plants to a Fiber Deep (FD) Architecture. FD architectures move the optical node (the optical-to-electrical conversion point) deeper into the network and closer to the subscriber. This means shorter copper, faster speed, more capacity and reduction in maintenance cost for both cable TV network and telephone line based access networks.
Ethernet: Faster Ethernet speeds are taken to use. These transitions are driven by the increasing global IP traffic. Hyper-scalers and service providers are moving from 100GbE to 400GbE Ethernet rates and beyond. In this speed development 56Gb/s And 112Gb/s SerDes Matter.
TSN: Time-Sensitive Networking (TSN) is a set of standards under development by the Time-Sensitive Networking task group of the IEEE 802.1 working group. TSN standards documents that are specified by IEEE 802.1 can be grouped into three basic key component categories that are time synchronization; scheduling and traffic shaping; selection of communication paths, path reservations and fault-tolerance. Industrial Ethernet networks embrace time-sensitive networking (TSN) technology to integrate operational technology (OT) and information technology (IT).
SDN: Software-defined networking (SDN) technology is an approach to cloud computing that facilitates network management and enables programmatically efficient network configuration in order to improve network performance and monitoring. SD-WAN applies similar technology to a wide area network (WAN). SD-WAN allows companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS.
IPv6: IPv4 and IPv6 are the two Protocols Run the Internet in 2019. The long-forecasted day the internet runs out of addresses has arrived and it marks a paradigm shift in the internet’s evolution. Though IPv6 has been available globally since 2012, it has seen a slow, if increasing, adoption rate. The migration to IPv6 is inevitable but will take time during that both systems are in use. In many networks a notable amount of traffic is already IPv6.
New Internet protocols: Internet security gets a boost with TLS 1.3. Also HTTP is in process of switching to a protocol layered on top of UDP. Today’s HTTP (versions 1.0, 1.1, and 2) are all layered on top of TCP (Transmission Control Protocol) that is not very optimal in today’s applications as SSL over TCP requires subsequent round trips to establish the encrypted connection.
IoT: The IoT world is here, and the level and rate of convergence is increasing in volume and velocity. We will see the evolution of converged networks for IoT applications in mind. Network convergence (version 2.0) is here with changes and improvements made since the first converged network (Convergence 1.0). TIA TR-42 (Telecommunications Cabling Systems ANSI/TIA-568 family), BICSI (TDMM and others) and proprietary or third documents must adapt and adjust.
PoE: The IEEE 802.3bt standard, approved by the IEEE Standards Association Board on September 27, 2018, included some significant enhancements especially for LED lighting systems. This specification allows for up to 90W of delivered power for cable lengths of up to 100m through the use of all four pairs of wires.
Trade wars: It seem that there is a high tech “trade war” between USA and China. It affects specifically networking business. Big Chinese manufacturers Huawei and ZTE are have received sanctions and their products are not wanted by many countries citing their business practices and potential security nightmares. For example Japan to halt buying Huawei, ZTE equipment and Huawei has been under fire in UK, just to mention examples. It seems that the business that is lost by Huawei and ZTE could benefit Ericsson and Nokia in the 5G base station markets for short term.
Security: The internet is going to hell and its creators want your help fixing it. All agree on one thing however: Right now there is a serious battle for heart and minds, the future of the internet and global society itself. There seems to be need for a conference to address the fact that people increasingly see tech as a threat and no longer as a pure force for good. Government set to revise internal rules on procurement to protect national cybersecurity. Your DNS might be broken, and you don’t even know it. Some DNS old hacks gets thrown out of use by February 1st, 2019.
WiFi: WiFi technology gets new marketing naming. The numerical sequence includes: Wi-Fi 6 to identify devices that support 802.11ax technology, Wi-Fi 5 to identify devices that support 802.11ac technology, Wi-Fi 4 to identify devices that support 802.11n technology.
Faster mobile: Mobile networks are getting faster in many countries. Mobile networks are killing Wi-Fi for speed around the world. Average data speeds on mobile networks now outpace customer’s Wi-Fi connection, on average, in 33 countries. That’s the The State of Wifi vs Mobile Network Experience as 5G Arrives.
Energy efficiency: We need to develop more energy efficient networking technologies. Today, information and communication technologies globally consume 8% of electricity and doubles every year.

Best practices for deploying 802.11ax WiFi APs with Cat 6a cabling
https://www.cablinginstall.com/articles/2019/03/best-practices-6a-cabling-for-wifi-aps-nbaset.html?cmpid=&utm_source=enl&utm_medium=cim&utm_campaign=cim_data_center_newsletter&utm_content=2019-02-11&eid=289644432&bid=2388741
Since the introduction of WiFi technology over two decades ago, five major WiFi application standards have been published, with another (IEEE 802.11ax) expected to be ratified in 2019. Furthermore, additional work is underway on the next generation WiFi application standards.
NBASE-T Alliance’s BICSI Fall panel promotes benefits of 2.5G/5GBASE-T run over existing Cat5e/Cat6 cables
To ensure that businesses can sustain this pace and avail themselves of the latest WiFi technology, the cabling infrastructure that forms the backhaul between WiFi access point (AP) and switch must be designed to accommodate current and future standards. To achieve this objective, and support advances in remote powering technology, the recommended cabling design is to install two Category 6A cables per AP to support both current and future wireless technologies. Installing two Category 6A cables per AP provides optimal PoE performance, future proofing, design flexibility, and the potential through link aggregation to have up to 20 Gigabits of data for that AP.

Limited oversight, no competition, and state corruption aren’t a recipe for broadband success
Once as important as the American railroad and electrical grid, American phone companies aren’t quite what they used to be. With the use of copper-based landlines having plummeted the last few years, many of the nation’s phone companies have understandably attempted to shift their business models toward new, more profitable sectors
for many, slow, expensive DSL is the only broadband available. But with no local competition and local and federal oversight eroded by lobbying—many of these companies have simply stopped caring.

Security concerns about the role of Huawei in Western 5G telecom infrastructure are to be taken seriously, the head of NATO said Thursday, as Washington steps up pressure on Europe not to use the Chinese firm.
NATO Secretary General Jens Stoltenberg said the 29-member alliance has begun internal consultations on Huawei, which the US says poses a “threat” to Europe.
The US and several other Western nations have shut Huawei out of tenders for the development of super-fast fifth-generation, or 5G, networks, because of the company’s close ties to the Chinese government.
“Some NATO allies have expressed their concerns over Huawei and their role in providing 5G infrastructure. NATO takes these concerns very seriously,” Stoltenberg told reporters.

Why effective shielding matters in your structured cabling system
https://www.cablinginstall.com/articles/2019/03/why-effective-sheilding-matters-to-structured-cabling-systems-belden-blog.html?cmpid=&utm_source=enl&utm_medium=email&utm_campaign=cim_data_center_newsletter&utm_content=2019-03-18&eid=289644432&bid=2395486
There’s no doubt that a cabling system’s physical characteristics impact performance and reliability – but there’s another component of a high-performance cabling infrastructure to keep in mind: proper grounding, bonding and shielding.
In a recent Belden blog about grounding and bonding in telecommunications rooms, we covered the basics of grounding and bonding. Now we’re ready to talk about the other important component of a grounding and bonding system: an effective shielding system!
Why is Effective Shielding Necessary?
Depending on the surrounding environment, a cable can pick up interference being released from nearby sources. Shielding reduces the effects of this kind of EMI (electromagnetic interference) in cabling systems, which are usually areas of very high EMI.
Effective shielding protects cables from signal interference and increases practical operating bandwidth levels. The success of your shielding system depends on several factors:
Quality of cable installation and proper cable handling
Quality and reliability of shield terminations (the foil connection needs to make good contact with the connector housing)
Balance of the twisted pairs
Impedance of the ground connection
Ground potential difference between local and remote grounds
Myths About Effective Shielding
Effective shielding also prevents ground loops, which develop when there is more than one ground connection. If there’s a difference in common-mode voltage potential at these ground connections, noise is induced onto the cabling.
Many people think they can use an unshielded patch cord at the other end of the system’s shield, believing that this will break the flow of current from a large ground coupling and prevent a ground loop. But doesn’t correct the problem. If a common-mode voltage potential difference larger than 1v at each ground is present, then current will travel that path. Removing the shield at one end simply leaves it exposed to the next danger point. The problem still exists (and will likely come back to bite you later).
Belden recommends grounding at both ends of a shield. Otherwise, there may be a common-mode voltage potential difference and current may be flowing, leading to a ground loop. There should always be less than 1 Ohm resistance path to ground.
Effective Shielding: What the Standards Say
The standards that guide grounding, bonding and shielding include IEC 60364-1 and ANSI/TIA-607-C.
TIA standards dictate the following:
The shield of shielded, twisted-pair cables shall be bonded to the SBB or PBB (generally through terminating the cable shield to the connector)
The connector is bonded to the metallic panel frame, which is bonded per TIA guidelines
Voltage higher than 1 Vrms between the shielded cabling system at the equipment outlet and the ground wire of the corresponding electrical outlet expected to power the equipment isn’t grounded and, therefore, isn’t recommended.

1. Simple Deployment
2. High-Quality Transmission in Real Time
3. Ease of Management
4. Lower Cost
Networked solutions eliminate the expensive wall processors of the past and require less cabling, resulting in additional cost savings. The decreasing price of LED displays also reduces the cost of a video wall installation. Additionally, components such as the mounting brackets are being engineered for faster, and thus cheaper, installation.

FCC Admits in Court That It Can’t Track Who Submits Fake Comments
https://gizmodo.com/fcc-admits-in-court-that-it-cant-track-who-submits-fake-1833415042
The FCC’s public comment system is a bloody mess. Over the past two years, it’s become apparent that political lobbyists, usually acting on behalf of the telecom industry itself, are prepared to manipulate the agency’s rulemaking process and impersonate everyday Americans just to create the illusion of public support where, in reality, none exists.
In response to allegations that millions of comments submitted to the FCC about net neutrality in 2017 were fabricated—using the names and home addresses of Americans without their consent—the New York Times is actively seeking access to the FCC’s internal logs under the Freedom of Information Act. Its reporters have specifically asked the FCC to turn over records that contain every comment and the IP addresses from which they originated. But the commission is fighting back.
For starters, the FCC is denying the Times access to these records on privacy grounds
The notion that the system is in any way “secure” to begin with is comical, since one doesn’t need to actually commit a computer crime to flood it with bogus comments. If one were to email the agency and ask for instructions on how to submit comments in large batches, not only will it gladly provide that information, it will load them into the system regardless of whether they’re real or not.
Comments attributed to Americans who have been saying for over a year that their identities were stolen can still be found on the FCC’s website, right next to political (and in some cases veiled anti-Semitic) remarks that they did not write.
Americans should not have to worry about whether malicious political statements, which they did not write and do not stand by, are being published by their own government in their name, without their consent.

4G-liittymiä jo neljä miljardia
http://www.etn.fi/index.php/13-news/9250-4g-liittymia-jo-nelja-miljardia
Globaalisti LTE:n osuus kaikista kännykkäliittymistä oli vuodenvaihteessa 47 prosenttia.
Eniten LTE-liittymiä on suhteellisesti Yhdysvalloissa, missä 4G kulkee mukana 82 prosentilla kuluttajista. Aasiassa LTE:n osuus liittymistä on 67 prosenttia ja Länsi-Euroopassa 52 prosenttia.
Vuoden 2017 lopulta viime vuoden lopulle LTE-liittyminen määrä kasvo globaalisti miljardilla. 4G onkin ollut tähän asti nopeimmin yleistynyt mobiiliverkkotekniikka.

Internet speeds are getting faster and faster in the past few years, with Gigabit internet actually becoming available to many customers across the USA. But is it actually necessary? A lot of the marketing for Gigabit internet is just pure nonsense, with vague reasons. This video goes over reasons why you may actually want Gigabit, and also reasons against getting it.

Come along as I scope out not one, but two cell sites: one hidden in the steeple of a church, the other perched high atop the tallest mountain in the Northeast. In the process we’ll learn about RF energy, what happens when the power goes out, and why the term “tower” isn’t always accurate.

Report: YouTube is now responsible for 37% of all mobile internet traffic, ahead of Facebook’s 8.4%; media time spent on mobile in US rose from 21% to 24% YoY — Smartphones are the big gainers in media consumption year-over-year, according to the just-released Nielsen’s Q3 2018 Total Audience Report.
Mobile time-spent jumps up: YouTube corners ~40% of the traffic, Facebook less than 10%
https://whatsnewinpublishing.com/2019/03/mobile-time-spent-jumps-up-youtube-corners-40-of-the-traffic-facebook-less-than-10/
There’s been a significant jump in mobile time-spent among 18-34s, from 29% to 34%. The growth came at the expense of television viewing. This trend continues from a year earlier, as live and time-shifted TV (i.e., traditional cable and set-top box viewing) was surpassed by mobile in Q3 2017, and now that gap has widened even further.
For all US audiences, mobile went up from 21% to 24%, with media consumption otherwise remaining flat, at about 10.5 hours per day.
A Sandvine study (The Mobile Internet Phenomena Report, Feb 2019) found that YouTube is now responsible for 37% of all mobile internet traffic. Interestingly, Facebook is running neck and neck with Snapchat when it comes to mobile traffic, with both having less than 9%.

Facebook’s 60-GHz Terragraph Technology Moves From Trials to Commercial Gear
https://spectrum.ieee.org/telecom/internet/facebooks-60ghz-terragraph-technology-moves-from-trials-to-commercial-gear
For years, Facebook has been developing a technology to improve the way data is organized and routed in wireless networks. Now, that technology is being integrated into commercially available 60-gigahertz small-cell base stations. And if service providers sign on, it could soon help deliver over-the-air Internet to homes and businesses around the world.

A Better Way to Organize the Internet: Content-Centric Networking
https://spectrum.ieee.org/telecom/internet/a-better-way-to-organize-the-internet-contentcentric-networking
The Internet is more than 45 years old, and it’s starting to show its age. To be sure, it has served us wonderfully well. Its underlying technologies delivered the World Wide Web (still a young adult at around 28 years old) and our global communications network. Even as its user base has swelled to 3.4 billion, these technologies have scaled admirably.
Today, however, all of those users demand a level of performance that the Internet was never designed to deliver. The authors of the original Internet protocols, who began their pioneering work in the late 1960s, designed them for a network to be used mainly for sending electronic mail from one computer to another. Now, though, people spend far more time streaming Netflix movies. Oftentimes, one piece of content must be distributed to hundreds of thousands or millions of users simultaneously—and in real time.

The ‘splinternet’ is already here
https://techcrunch.com/2019/03/13/the-splinternet-is-already-here/
There is no question that the arrival of a fragmented and divided internet is now upon us. The “splinternet,” where cyberspace is controlled and regulated by different countries is no longer just a concept, but now a dangerous reality. With the future of the “World Wide Web” at stake, governments and advocates in support of a free and open internet have an obligation to stem the tide of authoritarian regimes isolating the web to control information and their populations.
Both China and Russia have been rapidly increasing their internet oversight,

Here are a few benefits that Wi-Fi 6 classified devices will offer to organizations pursuing and deploying IoT environments.
1. Extended Device Battery Life
2. Support for More Devices at One Time
3. Simultaneous Communication with Multiple Devices
4. Data Rate Increases
5. Faster, Easier Device Connections with MPTL
With IEEE 802.11ax will also come increased use of modular plug terminated link (MPTL) topology, which was approved by TIA in 2018. This configuration saves time and money by allowing a cable from a patch panel to supply data and power directly to a wireless access point without additional connections in between.
If MPTL is the installation method you choose to use when deploying IoT devices, Belden’s new REVConnect FlexPlug makes the process even easier.
Because it works with any IoT device that uses an RJ45 plug, the FlexPlug eliminates compatibility questions when connecting devices.

Any errors made during installation can result in significant costs.
Fiber installations are undoubtedly the most prominent media for the transmission of the massive amounts of data over short, medium, and long distances. When it comes to fiber installations, some often-overlooked practices are fairly critical in maintaining a fiber run’s signal integrity. This article aims to illuminate some common failure points of fiber runs and how to prevent them from occurring.
A tightening power budget
As fiber-optic technology advances, so does the inflexibility of the link budget.
