In cooperation with Micram, the Fraunhofer Institute for Telecommunications (Heinrich-Hertz-Institut) and Eindhoven Technical University, Siemens has successfully tested the network of the future. This involved the 100% electrical processing of data rates of 107 Gbits per second and transmission over a 100 mile long fiber-optic route in the U.S. – the first time this has ever been done outside the laboratory.
The record performance was made possible by a newly developed transmission and receiving system that processes the data by purely electrical means directly before and after its conversion into optical signals. The test was conducted at a long-haul network at one of world’s largest optical network operators, in which Siemens has previously deployed a 40 Gbits per second optical network for commercial use.
Ultra-high bandwidth capacity in core network will be required to cater the traffic generated by online games, music, and video downloads. By 2011, legal music downloads alone will account for 36 percent of the entire music business in Europe according to market research institute Forrester Research.

Across the border from Chinese-occupied Tibet, the tech infrastructure in this high mountain village is a mess.
But a former Silicon Valley dot-commer and members of the underground security group Cult of the Dead Cow are working with local Tibetan exiles to change that using recycled hardware, solar power, open-source software and nerd ingenuity.
The volunteers are building a low-cost wireless mesh network to provide cheap, reliable data and telephony to community organizations.

A simple tweak to the way common silicon transistors are made could allow faster, cheaper mobile phones and digital cameras, say UK researchers.
Devices with the modification have already set a new world record for the fastest transistor of its type.
To achieve the speed gain, researchers at the University of Southampton added fluorine to the silicon devices.
