Here's a news item: at
http://technews.acm.org/archives.cfm?fo=2008-03-mar/mar-24-2008.html#354574
it says: <<
"Intel Researchers Stretch Wi-Fi to Cover 60 Miles
Network World (03/20/08) Cox, John
Intel recently demonstrated an 802.11 radio link with a data rate of
approximately 6 Mbps and a range exceeding 60 miles. Intel facilitated
this rural connectivity platform (RCP) with off-the-shelf hardware and
modified the underlying 802.11 media-access-control layer to boost the
signal's efficiency. This involved the addition of a method known as
time division multiple access (TDMA) that is currently used in GSM
cellular networks and which splits the channel into time slots and
puts the sending and receiving radios in sync, effectively eliminating
waiting for acknowledgments and resending of data. The TDMA technique
extends the range by minimizing the wireless overhead and opening up
more bandwidth for data transmission. The RCP units can function as
endpoints that bookend each link or as relay stations to effect
signal-hopping. The RCP software uses an operating system based on the
SnapGear embedded Linux distribution. Pilot RCP deployments have been
established in India, Vietnam, Panama, and South Africa. RCP, which
Intel Research and Intel's Emerging Markets Platform Group has been
working on for around two years, is one of several efforts to extend
the Internet into rural regions, especially in developing nations,
through the employment of low-cost, low-power Wi-Fi radios."
