Clearwire deployed a proprietary broadband wireless access network based on Nextnet's technology. Nextnet was later bought by Motorola, who is a major infrastructure vendor for WiMAX, and Clearwire, as part of their merger with Sprint Xohm, will be switching to WiMAX.
WiMAX has two major variants: those based on the IEEE 802.16-2004 standard (called 16d or fixed WiMAX) and those based on the newer IEEE 802.16e-2005 (called 16e or mobile WiMAX) standard. There have been some small, limited build-outs of 16d, but 16e is destined to be much bigger, and that's why this is a big deal.
Sprint has been the primary backer of 16e because they acquired a lot of 2.5 GHz unpaired spectrum from their Nextel acquisition. With the launch of Sprint's Baltimore network, they've proven that a large, citywide network can deliver on the promises of WiMAX. This is a huge step forward for mobile broadband wireless access.
