Samsung announced today that their WiMAX network has passed Sprint's testing and is ready for a commercial launch. Samsung is one of three WiMAX vendors for Sprint, Motorola and Nokia are also providing infrastructure. The Baltimore and Washington D.C. network is being built using Samsung equipment, and will launch commercially later this year. There is no mention of the other providers passing testing, or when WiMAX will officially be launched, but hot on the heels of some big investors
this is another big hurdle cleared towards the nation's first 4G network.
