§  90.555   Information exchange.

   (a) Prior notification. Public safety licensees authorized to operate
   in the 763-775 MHz and 793-805 MHz bands may notify any licensee
   authorized to operate in the 746-757, 758-763, 776-787, or 788-793 MHz
   bands that they wish to receive prior notification of the activation or
   modification of the licensee's base or fixed stations in their area.
   Thereafter, the 746-757, 758-763, 776-787, or 788-793 MHz band licensee
   must provide the following information to the public safety licensee at
   least 10 business days before a new base or fixed station is activated
   or an existing base or fixed station is modified:

   (1) Location;

   (2) Effective radiated power;

   (3) Antenna height; and

   (4) Channels available for use.

   (b) Purpose of prior notification. The prior coordination of base or
   fixed stations is for informational purposes only. Public safety
   licensees are not afforded the right to accept or reject the activation
   of a proposed base or fixed station or to unilaterally require changes
   in its operating parameters. The principal purposes of notification are
   to:

   (1) Allow a public safety licensee to advise the 746-757, 758-763,
   776-787, or 788-793 MHz band licensee whether it believes a proposed
   base or fixed station will generate unacceptable interference;

   (2) Permit 746-757, 758-763, 776-787, and 788-793 MHz band licensees to
   make voluntary changes in base or fixed station parameters when a
   public safety licensee alerts them to possible interference; and,

   (3) Rapidly identify the source if interference is encountered when the
   base or fixed station is activated.

   (c) Public Safety Information Exchange. (1) Upon request by a 746-757,
   758-763, 776-787, or 788-793 MHz band licensee, public safety licensees
   authorized to operate radio systems in the 763-775 and 793-805 MHz
   bands shall provide the operating parameters of their radio system to
   the 746-757, 758-763, 776-787, or 788-793 MHz band licensee.

   (2) Public safety licensees who perform the information exchange
   described in this section must notify the appropriate 746-757, 758-763,
   776-787, or 788-793 MHz band licensees prior to any technical changes
   to their radio system.
