ACTA and SOPA – looks bad

ACTA, the Anti-Counterfeiting Trade Agreement, is a punishing, secretly negotiated copyright treaty that could send ordinary people to jail for copyright infringement. ACTA would establish a new international legal framework that countries can join on a voluntary basis and would create its own governing body outside existing international institution. ACTA has been negotiated in secret

Bitbang Ethernet

Implementation UDP into microcontroller Igor Atmel-UDP device: UDP/IP infrared remote control web page shows implementation UDP/IP on firmware level (similar as emulation of RS232 interface or USB interface). What makes it really cool is that the ethernet is bitbanged using nothing but the bare pins of an ATMEGA168. The downside is that this Ethernet implementation

UN wants two-thirds of the world online by 2015

Broadband technologies are fundamentally transforming the way we live. UN believes that communication is not just a human need – it is a right. The greater communication and understanding made possible through access to information and communication technologies. In today’s challenging economic climate, recent research has shown that broadband infrastructure and services contribute to economic

FPGA-based Ethernet switches

Ethernet switches are the ubiquitous building block of any intelligent network. Ethernet technology is deployed in virtually every organization’s data center. Wide Area Networking (WAN) and Metropolitan Area Networking (MAN) providers need to provide their customers with Ethernet services. Ethernet has also become the de facto networking technology in industrial automation even in mission-critical local

10GBase-T Technology

The growing importance of cloud computing along with the increasing utilization of unified data/storage connectivity and the advent of server virtualization have elevated the popularity of 10Gbps Ethernet.There are several connectivity options are available for 10Gbps Ethernet, both over optical fiber and copper cables. 10GBase-T Technology Revisited article tells that the lack of economical cabling

Wi-Fi for Video

Meeting the requirements for video-grade Wi-Fi Access Points article gives some interesting facts on transporting video over wireless LAN. Users are coming to expect a wireless video experience equivalent to video consumption over wires. Traditionally a Wi-Fi device was measured according to its receiver performance, using metrics such as receive sensitivity. With video delivery, transmitter

Cat 5 Cable Modeling

Category 5 (CAT5) cable is a multi-pair (usually 4 pair) cable that consists of twisted pair conductors, used mainly for data transmission. Basic CAT5 cable was designed for characteristics of up to 100 MHz. Newer CAT6 cable is designed form 250 MHz. Nowadays there are applications where those cables is used to carry higher frequencies.
