From what they told me, both tech support and also the UC Berkeley on campus demonstration, it's the modem has a raw data rate of 100kBps but the modem does about 28.8k performance. Then each small group of receivers connect to Metricom on a T1 then the Metricom connection to the net via AlterNet/UUNet is what I don't know... I'm in Chinatown San Francisco and I get about 36kBps throughput... Their techs aren't very informative it seems about their service.
