Sprint says WiMAX will be launched by year-end

Sprint Nextel is preparing to launch its first commercial WiMAX wireless broadband services in Washington and Baltimore in the fourth quarter of this year. The firm originally intended to have already launched networks in major cities across the US, but has so far had to content itself with limited trial WiMAX switch-ons in these two cities, plus Chicago. Sprint has formed a joint venture with Clearwire and a number of other partners to create a nationwide WiMAX network.
