I know the people who run that link, and that link is not what you
think it is. It uses different firmware in the lucent card which
enhances the card using a proprietary encryption and compression system.
300k/sec is practible using Turbocell firmware software and 25db arials. 
Standard 802.11b isn't. Its costs around $800 for that special firmware. 
150kb/sec is still the go.
