Chicago and Washington DC will be the first two locations to see Sprint and Motorola WiMax deployment this year, according to a Motorola press release. "Motorola will deploy WiMAX infrastructure to at least 1,000 sites in the greater Chicagoland area, providing select area coverage that complements Sprint Nextel's existing EV-DO network," says the company. Network trials are scheduled for late 2007, with commercial launch in early 2008.
