wi-fi (802.11b) through the use of active beam steering can significantly increase the effective range of WLAN. The typical effective range currently is up to about 1500ft for 802.11b. The bandwidth degrades the further you are from the access point (antenna). The post copied below submitted previously contains a link stating the effective range was increased to 7 Km through better antenna design incorporating active beam steering. The active beam steering antenna also permitted usage by slow moving users. i.e. Personnel walking with PDAs etc.. The system could not be used by mobile users in a car.
