Ethernet in the first mile

https://en.m.wikipedia.org/wiki/Ethernet_in_the_first_mile I came by a device with 2BASE-TL ports in it. Google search revealed that this standard was made by IEEE Ethernet in the first mile (EFM) working group. It standardizes networking techbologies for the customer’s point of view it is their “first” mile, although from the access network‘s point of view it is known as the “last mile“.  I know

Zyxel gigabit switch

I decided to replace my aging Zyxel and Netwjork 100 Mbit/s Ethernet switched with new gigabit models. I decided to get two ZyXEL GS-108S v2 Media Switch as replacement for those. The Zyxel GS-108S v2 10/100/1000 Mbps switch is designed to provide reliable high-performance media network connectivity – that’s what I need. The Zyxel GS-108S

Brotli compression algorithm for faster web

https://opensource.com/article/17/1/brotli-compression-algorithm?sc_cid=70160000001273HAAQ Brotli is a new open source compression algorithm designed to enable an Internet that’s faster for users. While the Brotli algorithm was announced by Google in September 2015, only recently have the majority of web browsers adopted it and HTTP servers started to offer Brotli compression. Brotli accomplishes better than gzip compression by making use of a

Ethernet switch teardown

Here is tear-down of old Zyxel  ES-108 10/100Mbit/s Ethernet switch. I had one on my network for many years, but one day it stopped worked and started making whining noise. Look inside. Closer look to details. Main Ethernet switch chip is ADM6999 from ADMtek (now part of Infineon). In addition to it line transformers and power

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
