Hi ftth,

US FCC Part 90 Personal Communications Services allow nomadic operation (FRS/GMRS, etc) without frequency coordination, but impose the obligation to work together to resolve interference. Part 90 Subpart y is US 4.9 GHz Public Safety, and Subpart z is US 3650 MHz Contention Based Protocol (which 802.16h is working to standardize).

US Part 101 Fixed Communications requires frequency coordination in most bands or path coordination in the 70/80/90 GHz band. In the 70/80 GHz bands, 71-76 GHz is paired with 81-86 GHz operation. TDD is not allowed. At a building or location, the first registered device has the choice to transmit in the 70 GHz band (East) or the 80 GHz band (West), and all subsequent transmitters at that location must use that band as coordinated with a path coordinator. This was called East West frequency planning in WCA. The objective of this rule is to prevent an operator from installing transmitters in both bands and claim that any additional operators would cause interference.

My point is the WiMAX paper does not cover any aspects of regulation that foster broader use of spectrum, just more of the exclusively licensed, frequency coordinated, Part 101 microwave use.
