LMCC Asks FCC to Make Changes to 800 MHz Order

of the interference contour to be used in coordinating an 800 MHz Mid-Band (809-817/854-862 MHz) application and the derating factors to be applied in that contour analysis,” said a petition posted Friday in docket 15-32. “The derating factors, which were developed for use with an F(50,50) curve, are not appropriate when applied to a more conservative F(50,10) curve.” The rules will mean “more adjacent channel protection than needed while simultaneously reducing the spectrum utilization that otherwise could be derived from introducing interstitial channels into the 800 MHz band,” LMCC said. The Monitoring Association, meanwhile, sought reconsideration of the rules for low-power pool group D frequencies. The group said it demonstrated in the record “that this small handful of channels are dedicated to sending safety of life and property messages, in direct cooperation with public safety; … are heavily used, and demand is growing due to the retirement of the copper phone network and rapid changes in cellular formats; that the licensing of non-central station operations, especially those allowing voice communications, can disrupt the timely delivery of alarm signals reporting fires, home invasions, medical alerts and other emergency situations; and that there was no demand demonstrated in the record for non-central station use of these channels.” No one “refuted these showings,” the association said.
