The Boeing Company
The Radio Regulatory Technical Advisory Group is the interface between 802 Wireless Working Groups (802.11) and national and international regulators of radio rules and regulations. It’s function is to respond to inquiries and requests for comments by those regulators, and to propose rules changes that WGs require for their functionality

Significant Events
Two telecons on Industry Canada Consultation, s
IC Consultation:
SMSE Using UWB Technology
SG1 formed to develop a standard on Regional Area Networking to utilize spectrum commonly known as the TV broadcast band. This was done to assist FCC in defining usage of this spectrum that they were considering opening to unlicensed service. About the time SG1 was formed, the Commission published a Notice of Proposed Rule Making (NPRM) on usage of this band and invited comments by 1 September 04. The RR-TAG requested the Commission extend the comment deadline, explaining the intent of SG1 and citing the cooperative efforts within the group by members of the incumbent spectrum users and members of 802 WGs in defining acceptable sharing scenarios.
SG1 has been approved by the 802 WGs and in the agendas of the New Standards Committee (NesCom) and Review Committee (RevCom) for final approval for becoming WG22 at their meetings in late September.

No Motions on Consultations
In the process of developing comments in response of the NPRM, several impasse points arose within the group. In order to proceed, three classes of service were define and agreed to by the group. It was further agreed that the group would work on commenting to the Commission on Fixed Point to Multipoint service first where consensus was strongest. If time permits and consensus can be attained, the group would provide comments on the other classes, or at least provide information as to the areas of contention in our comments to indicate the challenge in spectrum sharing in those classes of service.

5. Contention Based Protocol
January 2005
Contention Based Protocol
A protocol … to share … spectrum by defining the events that … occur when two … transmitters attempt to … access the same channel and ... rules by which a transmitter provides reasonable opportunities for other transmitters to operate. (FCC 05-56, amending 90.7)
