Clearwire is sort of cool, but I have also found that it is limiting in both accessibility and with their TOS (Terms of Service). As for any money generated. Well, I consider it to be relative.

Craig McCaw’s broadband wireless firm Clearwire raises $600m from Intel Capital, $300m from others: The latest revolutionary wireless firm founded by McCaw aims to deploy mobile broadband wireless worldwide using mobile WiMax (part of 802.16e-2005). Part of the money comes from Motorola purchasing Clearwire’s NextNet equipment subsidiary, which has been manufacturing and prototyping gear for Clearwire’s network, starting with customer premises equipment (CPE), or the fixed receivers plugged in at homes.

Clearwire owns the second-largest portfolio of spectrum in the desirable 2.5 GHz band in the U.S.; Sprint Nextel is the biggest holder. This is a great band into which to deploy mobile WiMax because of the geographic coverage—Clearwire says that they can reach 90m residents with current licenses—and the channelization, which is wide enough to allow sufficient bandwidth for real mobile applications, including video. (While BellSouth owns a chunk in 2.5 GHz, their biggest holdings are in 2.3 GHz. They are already looking at equipment that would offer WiMax or WiMax-like services in both bands. This spectrum is part of AT&T-formerly-SBC’s desire to purchase BellSouth, which would also give AT&T 100-percent ownership of Cingular, and allow more combined offerings there across DSL, cell data/3G, and WiMax.)… Source: wifinetnews.com
