We are required by the license to "prior frequency coordination with 2—GHz microwave users and consent of PCS licensees to avoid interference". AT&T engaged Ericsson Frequency Coordination Services along with Comsearch to coordinate the channels per the license requirements. Comsearch contacted T—Mobile, Sprint, Cingular, and Verison. The responses that were received from the service providers were negative. We are now looking for some suggestions as to how to proceed given that the service providers are unwilling to assist us in the coordination process. You can contact me at my office at 973—236—6915 or my cell phone at 973—727—5564. Best regards, Harry Worstell Vice Chair, IEEE 802.11 Working Group SR.
