Sec.  90.555   Information exchange.

   (a) Prior notification. Public safety licensees authorized to operate in the
   764–776 MHz and 794–806 MHz bands may notify any licensee authorized to
   operate in the 747–762 or 777–792 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 747–762 or 777–792 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 747–762 or 777–792 MHz band
   licensee whether it believes a proposed base or fixed station will generate
   unacceptable interference;

   (2) Permit 747–762 and 777–792 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 747–762 or 777–792 MHz band licensee, public safety
   licensees authorized to operate radio systems in the 764–776 and 794–806 MHz
   bands shall provide the operating parameters of their radio system to the
   747–762 or 777–792 MHz band licensee.

   (2) Public safety licensees who perform the information exchange described
   in this section must notify the appropriate 747–762 or 777–792 MHz band
   licensees prior to any technical changes to their radio system.
