Venerable Ethernet provides the backbone of the internet. Ethernet has risen to complete dominance for local area networks over its forty years of existence. The first Ethernet experimentals versions started in 1972 (patented 1978). The commercialization of Ethernet started in 1980′s. At first Ethernet technology remained primarily focused on connecting up systems within a single →
Nowadays it is possible to buy passive and active device to run Ethernet over Coax – some products support data transfer over larger distances then you can get on regular Cat5. The passive converters are typically limited to 100 Mbps maximum speeds up to 100-200 meters distance maximum. If you need faster speed or longer →
In this post I am talking about adapting 10 and 100 megabit twisted pair Ethernet to use coaxial cable instead of twisted pair wiring. Those 10BASE-T and 100BASE-TX Ethernet st standards use two wire pairs for communications (one for TX and other for RX). In this article I am describing how to adapt them to →
Ethernet started as a network that runs over coaxial cable. Over years the Ethernet has started to use mainly twisted pair wiring and fiber optics for communications. There seems to be every now and then still questions related to running Ethernet over coaxial cabling. This is the first part of multi-part post on running Ethernet →
Ethernet has risen to complete dominance for local area networks over its forty years of existence. The first Ethernet experimentals versions started in 1972 (patented 1978). The commercialization of Ethernet started in 1980′s. Today, Ethernet is everywhere. It’s evolved from a 2.93-Mb/s and then 10-Mb/s coax-based technology to one that offers multiple standards using unshielded →
Telecommunication and networking has been and will be one of the core technologies in helping the evolution of mankind and technology. Here is a quick view to the history of the modern electronics based communications technologies with help of few history articles. “10th March, 1876 – The day when Alexander Graham Bell made the first →
Ethernet co-inventor David Boggs dies at 71 https://www.engadget.com/ethernet-co-inventor-david-boggs-dies-at-71-110524422.html Pioneering Xerox PARC computer researcher David Boggs has died at 71, The New York Times has reported. Boggs was best known for co-inventing the Ethernet with Bob Metcalfe. Boggs joined the team in 1973, and started working with fellow researcher Bob Metcalfe on a system to send →
Ethernet cables are all often too long or too short. People on Reddit are competing to invent the shortest possible working ethernet cable. Ethernet cables are easy to crimp together yourself, and industrious folks on Reddit are currently engaged in a race to see who can make the shortest working length of ethernet. The results →
I got some TAIYO YUDEN 9012R0 LEADED COMMON MODE CHOKE COILS FOR AC LINES and thought some uses for them. The specifications for those from datasheet were: TLH10UA 901 2R0 RoHS Common mode inductance (mH): 0.9 min. Normal mode inductance (mH): 0.067 DC resistance: 0.089 Rated current (A max): 2.0 Rated voltage AC (V max): →
LANtenna hack spies on your data from across the room! (Sort of) post tells that Mordechai Guri from the Ben Gurion University of the Negev (BGU) in Israel has recently published a new data exfiltration’ paper detailing an unexpectedly effective way of sneaking very small amounts of data out of a cabled network without using →
