Schools Profit from Clearwire, Sprint License Purchases

By Glenn Fleishman

The LA Times uncovers a fact that those of us following WiMax know: schools are reaping a huge payday and other help from their spectrum licenses: The LA Times has a lot of specifics about how academic institutions, granted licenses for distance learning and broadcasting, have managed to take in hundreds of millions of dollars that benefit their students and campuses. The 2.5 GHz band that these schools hold geographic licenses to can be leased to commercial entities under rules set by the FCC to make better use of the band. Some of the sublessors have paid for schools to move broadcasts from analog to digital, improving their service and freeing up bandwidth, as well as licensing fees. The paper estimates that 1,400 agreements have been signed to lease spectrum.

WiMax Gets ITU Nod as Advanced Radio Standard

By Glenn Fleishman

Mobile WiMax’s inclusion in a global wireless broadband standard means that it can be used over standard bands approved for this purpose: IMT-2000 is a set of five radio standards linked to other elements that have been approved by many different authorities for use over advanced wireless bands in their various countries and regions. The two most popular are W-CDMA (GSM 3G) and CDMA2000 (CDMA 3G). By gaining ITU approval for mobile WiMax (really, 802.16 in this context), this dramatically increases the odds that it can be deployed more widely by not requiring special approval or specific bands. It also provides mobile WiMax as a migration possibility for carriers that haven’t yet deployed 3G.

Early mobile WiMax profiles from the WiMax Forum cover 2.3 GHz, 2.5 GHz, and 3.5 GHz, the most common currently available bands worldwide. (5.4 and 5.8 GHz mobile WiMax isn’t covered by approved profiles, but the same technology may be used on those bands as on the profiled bands.)

The news was made public on a mailing list for those involved with IEEE 802.16 by Roger Marks, the working group’s chair.

DragonWave Acts as EarthLink Licensed Backhaul

By Glenn Fleishman

DragonWave announces that EarthLink will use its licensed backhaul service: EartLink’s metro-scale networks will aggregate clusters of Wi-Fi mesh nodes through Motorola Canopy and pre-WiMax point-to-multipoint systems, which in turn will aggregate to high-speed licensed wireless backhaul. DragonWave’s system uses what they call wireless Ethernet that can offer a gigabit per second of service—up to 500 Mbps in each direction.
