Evolution of Mobile Communication from 1(G) to 4G, 5G, 6G, 7G …

http://vitorr.com/post-details.php?postid=2615 The cellular wireless Generation (G) generally refers to a change in the nature of the system, speed, technology and frequency. Each generation have some standards, capacities, techniques and new features which differentiate it from the previous one. Now 5G is hot technology at the top of the hype cycle. But that’s not the end

Severe flaw in WPA2 protocol leaves Wi-Fi traffic open to eavesdropping | Ars Technica

https://arstechnica.com/information-technology/2017/10/severe-flaw-in-wpa2-protocol-leaves-wi-fi-traffic-open-to-eavesdropping/ An air of unease set into the security circles on Sunday as they prepared for the disclosure of high-severe vulnerabilities in the Wi-Fi Protected Access II protocol that make it possible for attackers to eavesdrop Wi-Fi traffic passing between computers and access points.  There is a proof-of-concept exploit called KRACK, short for Key Reinstallation Attacks. KRACK

Topological Laser Cavities Could Revolutionize Optoelectronics – IEEE Spectrum

https://spectrum.ieee.org/tech-talk/semiconductors/optoelectronics/topological-laser-cavities-could-revolutionize-optoelectronics  A new type of laser cavity that builds off a Nobel-winning development in physics can take on any shape and switch the flow of light with a magnetic field. Kante and his colleagues describe their so-called topological cavities in the current issue of Science.  Normally, a laser cavity, where light amplification takes place, is shaped like

Tuning for Zero Packet Loss in Red Hat OpenStack Platform

http://redhatstackblog.redhat.com/2017/07/11/tuning-for-zero-packet-loss-in-red-hat-openstack-platform-part-1/?sc_cid=7016000000127ECAAY For Telcos considering OpenStack, one of the major areas of focus can be around network performance. While the performance discussion may often begin with talk of throughput numbers expressed in Million-packets-per-second (Mpps) values across Gigabit-per-second (Gbps) hardware, it really is only the tip of the performance iceberg. The most common requirement is to have

Delivering 5G mmWave fixed wireless access | EDN

Fiber optic termination and splicing

We terminate fiber optic cable two ways – with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers. According to Which field-termination method best fits your fiber-optic LAN? article over the

Future cyber security threats and challenges: Are you ready for what’s coming? | CSO Online

https://www.csoonline.com/article/3226392/security/future-cyber-security-threats-and-challenges-are-you-ready-for-whats-coming.html?_lrsc=83557c1d-a1a2-4e91-a200-fe1c9f71d03f The world is changing, and with it so is the internet. Or perhaps it’s the other way around. The internet continues to create new business and social opportunities that massively scale and widely interconnect. The increasing depth and volume of personal and corporate data make it a more rewarding target for cyber crooks and
