EWA to Launch Exclusive-Use Channel Validation Program
Wednesday, July 27, 2016 | Comments

The Enterprise Wireless Alliance (EWA) announced plans to launch an exclusive-use channel validation program that will verify the accuracy of all business/industrial applications that certify exclusive-use channels in the bands below 470 MHz.

Every business/industrial application filed at the FCC, no matter which frequency advisory committee (FAC) certified the application, will be processed through EWA’s automated frequency coordination system, EWA said in a letter. Any application that appears to have violated FCC Rule Section 90.187 will be identified and reviewed for compliance.

If an FB8 certification was not issued in accordance with the FCC rules, parties responsible for the application will be notified by EWA and requested to amend that application. If an incumbent system’s FB8 channel is violated, parties responsible for the application will be notified by EWA and requested to amend that application. Any affected incumbent licensee will also be informed of the potential risk to their radio system investments.

In the 150 – 470 MHz private land mobile bands, the coveted channel designation is an FB8, which signifies that the channel, whether in use within a private carrier or private internal trunked system, need not be monitored prior to use as it is exclusively assigned within the predicted service area based on specific technical information unique to the transmitter site. An incumbent system’s predicted interfering contour must not overlap an FB8 applicant’s proposed service area, and the FB8 applicant’s proposed interfering contour must not overlap incumbent system predicted service areas.

EWA said its members who are fortunate to have a channel or channels designated as FB8s need to be assured that all new certified applications recognize the existence of their system and do not corrupt their protected, exclusive service area. Further, because FB8-designated channels are not required to monitor before transmitting, the newly certified FB8 channels must be properly assigned or the potential for harmful interference dramatically escalates.

EWA is the FCC’s first line of defense in responding to instances of interference on behalf of business/industrial licensees, said the letter signed by Robin Cohen, EWA executive director, regulatory affairs and spectrum strategies.
