Mobile Versus Fixed WiMAX?

Nobody yet knows what percentage of WiMAX customers will use the access technology in fixed mode, compared to mobile mode. If Motorola is right, about equal numbers of each, with a smaller percentage, perhaps up to 20 percent, operating in both fixed and mobile mode. 

Globally, it seems likely that fixed access will be much of the demand. In the U.S. market, though virtually all current users are in fixed mode, the new Clearwire operation should result in a growing percentage of mobile users.
