A little-known start-up has demonstrated wireless broadband 1000
times more efficient than WiMax – and claims the technique could also
make wireless LANs that will run for years on watch batteries.
Technology, based in Sarasota, Florida, used a transmitter not unlike a
cordless phone base station, operating in the unlicensed – and crowded
– 900MHz band, to send a 3.7Mbit/s data signal to a radius of 18 miles
across the suburbs of Miami, using 50mW and an omnidirectional antenna.
The data rate and specifications don’t exactly match xG’s original plan, which we reported in July,
as the demo uses a narrower band and a lower data rate. However, with
an omnidirectional antenna, the demonstration appears to have
transmitted a signal at a power density other schemes would find
impossible. The company’s xMax technology uses a novel modulation
scheme, described at xG’s own site.
Motorola V65p Push to Talk Phone (Verizon Wireless)
This basic phone from Motorola just got better. Like its predecessor, the V60p, it has push-to-talk capabilities, but with the addition of a color main screen and a larger supplementary screen. With a push-to-talk subscription from Verizon Wireless, yo…
