were to require some system of exclusion zones, it could ensure that VLP exclusion zones would be no larger than a 6 GHz automated frequency coordination system would have computed for a device at the same power level,” said a filing posted Thursday in docket 18-295. “At the very least these exclusion zones should account for 3 dB of polarization mismatch loss, up to 3 dB of feeder loss (depending on the Fixed-Service radio), and a Fixed-Service receiver noise figure of 4.0-4.5 dB, depending on frequency,” they said.
