Steve Stroh says today's FCC reworking of the MMDS/ITFS band makes sense, but will be for naught: Read Daily Wireless's explanation of the move for details, but broadly, almost 200 MHz of sweet-spot spectrum in the 2.5 to 2.7 GHz range that's been carved up and relicensed in unpleasantly small and low-utility ways will be restructured for more utility and continuity.
Stroh notes, however, that the FCC has opted out of the process by which the transition of existing users will take place. This means that the owners and users of the band have to figure it out. Stroh feels that currently deploying fixed broadband wireless companies have a huge advantage over those that were expecting to carve out new space in this band. Stroh also expects this entire band to go license-exempt within 10 years.
Daily Wireless remarks that the 6 MHz sub-bands in the revision fits cellular 3G's needs. In the CDMA world, 1x = 1.25 MHz, as in 1xRTT and 1xEv-DO; 3x = 5 MHz. The service currently hosts a very small number of actually instructional television broadcasters, and they'll have new contiguous channels to use.
