[Asterisk-Users] Asterisk + WiFi Phones

Wed Nov 23 15:49:11 MST 2005

Yeah the 480i-CT is a nice product, and not subject to the 
inconsistencies of WIFI.  What impressed me about the Engenius handsets 
was the range.  250,000 square feet coverage, or 3,000 acre coverage in 
an outdoor application, off a single radio AP, that's a large footprint.
