Public safety/CII licensees may notify a commercial aviation air-ground system licensee that they wish to receive prior notification of the activation or modification of a commercial aviation air-ground system ground station site in their area. Thereafter, the commercial aviation air-ground system licensee must provide the following information to the public safety/CII licensee at least 10 business days before a new ground station is activated or an existing ground station is modified:\n(1) Location;\n(2) Effective radiated power;\n(3) Antenna manufacturer, model number, height above ground level and up tilt angle, as installed;\n(4) Channels available for use.\n(b) Purpose of prior notification. The prior notification of ground station activation or modification is for informational purposes only: public safety/CII licensees are not afforded the right to accept or reject the activation of a proposed ground station or to unilaterally require changes in its operating parameters. The principal purposes of prior notification are to:\n(1) Allow a public safety licensee to advise the commercial aviation air-ground system licensee whether it believes a proposed ground station will generate unacceptable interference;\n(2) Permit commercial aviation air-ground system licensee(s) to make voluntary changes in ground station parameters when a public safety licensee alerts them to possible interference; and\n(3) Rapidly identify the source if interference is encountered when the ground station is activated.","path":["Title 47—Telecommunication","CHAPTER I—FEDERAL COMMUNICATIONS COMMISSION","SUBCHAPTER B—COMMON CARRIER SERVICES","PART 22—PUBLIC MOBILE SERVICES","Subpart G—Air-Ground Radiotelephone Service"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-47.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:28Z","sha256":"79cf3b29f1a0ec892aa0bf1a35e9dac43bf8da200b9fde3181b129a699b1803f","source_id":"us-cfr","stale":true,"prev":"us/47-cfr-22.879","next":"us/47-cfr-22.881"},"notice":"GroundRules: Original legal text.
