MAY 28-30, 2008: International Summit for Community Wireless Networks -- Washington, DC. Please help spread the word! The New America Foundation, CUWiN Foundation, the AAAS Science and Human Rights Program, and the Acorn Active Media Foundation will be hosting the annual International Summit for Community Wireless Networks in Washington, DC on May 28-30, 2008. More information will be forthcoming at wirelesssummit.org in coming weeks. Hosted by the world?s largest general scientific society, the American Association for the Advancement of Science (AAAS), this year?s summit will continue its tradition of featuring wireless leaders, innovators, activists, and community networking visionaries from around the globe. ?With large-scale network implementations demonstrating the viability of open source wireless technologies, and corporate franchise business model faltering, the movement is at a critical juncture in its development? states Sascha Meinrath, Summit Director. ?This year's International Summit for Community Wireless Networks will explore issues of global integration and local control over these vital communications media.? Additional summit topics include: The role of community wireless networks in supporting human rights The current state of US and international telecommunications policies Exploration of state-of-the-art FOSS wireless technologies Social networking and other WLAN services and applications Community wireless updates from Europe, Africa, South America, and Asia White space devices, ?device as infrastructure? networks, & disruptive tech Legal issues in community wireless networking Alternative business models and sustainable networking *** About the Acorn Active Media Foundation: The Acorn Active Media Foundation engages in software, website and technical development in support of the global justice movement. Acorn's commitment to its work stems from a foundational philosophy that its projects should align with the Foundation's goals to support social and economic justice.

Happy Eid, Chirstimas and New Year. I hope it's OK to forward this. I read it and thought it was great use of WiFi for D. Jordan now has WiMax BTW. All the best, R Doctors assess patients over long distance wi-fi connection Source: Source: eHealth Online (www.ehealthonline.org) Date added: 2007-12-09 Country: India [IN] Sector: Health Residents of remote villages in southern India now have easy access to eye care thanks to a specially designed, low-cost and long-distance wi-fi network.The network allows specialists at Aravind Eye Hospital at Theni, in the state of Tamil Nadu, to virtually examine patients in nine remote clinics via high-quality video conference. The new technology developed by researchers at the University of California, Berkeley and at Intel Corporation in collaboration with the Indian hospital, was the result of research targeted towards the demands of the developing nations, with requirements for inexpensive and robust wireless networking technology. The Berkeley scientists adapted existing wi-fi technology, as an alternative to the wimax technology which is expensive. The key challenge is that wi-fi is designed for short, and not long distance communication. They discovered that one can get the radio signal to go further just using better antennas. However, in doing so, one has to pick a particular direction for the signal. This long-distance wi-fi is a fixed, point to point wireless technology, like microwave links. This could revolutionise the delivery of health care services and greatly improve the quality of life in the rural developing world. The innovation for the India wi-fi system was to provide high bandwidth, for high quality video imaging, over long distances. The researchers redesigned the software, so that some of the unneeded information typically sent over a wi-fi connection was discarded. By combining their modified software with directional antennas and routers to send, receive and relay signals, the research team so far has been able to obtain network speeds of up to six megabits per second (Mpbs) at distances up to 40 miles. But the team has obtained even more impressive results, in their current world record, they achieved almost 6 megabits/second over a distance of 384 kilometres using only one link. These tests were carried out in a project in Venezuela last summer. Vision centres in the region are now conducting real-time eye exams with doctors in Theni, over a direct connection 150 times as fast as the old dial-up modem, which used to cost $200 a year.
