# §22.880. Information exchange.

- (a) **Prior notification.** 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:
  - (1) Location;
  - (2) Effective radiated power;
  - (3) Antenna manufacturer, model number, height above ground level and up tilt angle, as installed;
  - (4) **Channels available for use.**
- (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:
  - (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;
  - (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
  - (3) **Rapidly identify the source if interference is encountered when the ground station is activated.**
