Research firm Maravedis has a new study out on the licensed 2.5 GHz Broadband Radio Service (BRS) and the licensed 2.3 GHz Wireless Communications Service (WCS) band. They calculate the number of licenses and coverage in the 2.3 and 2.5 GHz bands.

Those frequencies are critical for the future of mobile WiMax in the United States. Without them it's not going anywhere.

Under the FCC terms of the Sprint Nextel merger, Sprint agreed to offer at least 15 million Americans broadband wireless access within four years, and an additional 15 million potential subscribers within six years using their 2.5 GHz frequencies.

In 2004, the FCC changed the MDS/ITFS frequency plan. Commercial Broadband (BRS) and Educational (EBS) broadband services are now allocated differently. The television oriented EBS service was moved in the middle of the band to reduce interference with the weaker 2-way data services.

As of November 2005, over 1,700 BRS Licenses and 2,500 EBS Licenses (formerly ITFS) were listed on the FCC's ULS License Search web site. The FCC's Tower Search has additional information. Maravedis estimated the broadband wireless licensees (below), from the FCC's ULS License Search web site.

Licensee PSA BTA Potential Subs
BellSouth Wireless 36 6 9,070,577
Clearwire 59 24 4,693,347
Nextel/Sprint 268 198 157,519,832

Protected Service Areas (PSA) is an exclusive license service granted to either a BRS or EBS licensee. Each PSA is comprised of a 35 Mile Radius surrounding the licensed transmitter site.

Basic Trading Areas (BTA) is geographic region defined by a group of counties that surround a city as formulated by Rand McNally. There are 493 BTAs in the U.S.

Owners of incumbent MDS (now called BRS) and ITFS (Instructional Fixed Television Service) (now called EBS), hope mobile WiMax, likely to be available in a year or two, will take off. EBS television licensees must have a minimum of 20 hours per 6 MHz channel per week of educational use of EBS spectrum.

The 2.3 GHz WCS band, currently has a total of 282 x 5.0 MHz licenses, according to Maravedis. Many of the 2.3 GHz WCS licenses, granted in 1997, will be due to expire in 2007. The FCC gave considerable flexibility to satellite radio's 2.3 GHz DARS (Digital Audio Radio Service) to put their satellite "gap fillers" where they need them (and even where they don't).

Some fear the 2.3 GHz band will be one big mess resulting in interference between broadband wireless providers and satellite radio repeaters -- just like the FCC screwed up with Nextel. Or maybe the problem will just disappear if XM satellite radio buys out the 2.3 GHz broadband wireless band for their own purposes.

WiMax at 2.3GHz? Forgetaboutit.

Satellite radio, at 2.3 GHz, is NOT going away in the United States.

It's taking over.

Bell South hoped to provide WiMax at 2.3 GHz. Just like Korea. Instead, Bell South has become a voice in the wilderness. Overpowered by 2000 watt transmitters, restricted by spectrum allocations, out maneuvered by lobbyists.

The FCC doesn't have a plan for broadband wireless access. Maybe Kevin Martin has a plan. Oh, no wait...he's already a lobbyist.

The FCC also moved to open up the 3.5 GHz band, particularly for rural populations. But the 3.6GHz spectrum will be shared, unlike the 2.5GHz and 2.3GHz bands.

Other frequency options include the 5.8 GHz band with 100 Mhz of unlicensed bandwidth - but the restricted range and unlicensed nature makes mobility impractical. The 700 Mhz band is expected to have good range and might be an option in 3-4 years, but the 6-12 Mhz bandwidth will limit capacity of any licensed 700 Mhz network.

The FCC can appear to be insular with industry lobbyists guiding FCC policy. Why, for example, isn't there more information on the proposed buyout of the 2.3 GHz band by XM radio? Inquiring minds want to know.
