Re: 95% can be real if... it determines what 95% coverage is.
WiMAX is not as inexpensive as, say, Motorola Canopy on the tower end ($12k for a second order diversity system plus antennas versus several thousand for Canopy versus less for other systems). However the subscriber units aren't all that bad; $350 or so for something that, with an antenna, can do well in rural areas, if you know where to look.
