Sec.  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.
