Sprint has soft launched its WiMAX network this week in Chicago and Baltimore-Washington D.C. as planned. The initial trial is limited to Sprint employees only and the carrier has not disclosed what hardware the users will have to connect to the network. Nokia and Samsung have both inked deals with the carrier for WiMAX-enabled devices. These initial test markets will become commercially available during the first quarter of next year and Sprint expects a full commercial launch during the second quarter of 2008.
