Sec.  15.510   Technical requirements for through D-wall imaging systems.

   (a) The UWB bandwidth of an imaging system operating under the provisions of
   this section must be below 960 MHz or the center frequency, f[C], and the
   frequency at which the highest radiated emission occurs, f[M], must be
   contained between 1990 MHz and 10600 MHz.

   (b) Operation under the provisions of this section is limited to
   through-wall imaging systems operated by law enforcement, emergency rescue
   or firefighting organizations that are under the authority of a local or
   state government.

   (c) For through-wall imaging systems operating with the UWB bandwidth below
   960 MHz:

   (1) Parties operating this equipment must be eligible for licensing under
   the provisions of part 90 of this chapter.

   (2) The operation of these imaging systems requires coordination, as
   detailed in  Sec. 15.525.

   (3) The imaging system shall contain a manually operated switch that causes
   the transmitter to cease operation within 10 seconds of being released by
   the operator. In lieu of a switch located on the imaging system, it is
   permissible to operate an imaging system by remote control provided the
   imaging system ceases transmission within 10 seconds of the remote switch
   being released by the operator.

   (4) The radiated emissions at or below 960 MHz shall not exceed the emission
   levels in  Sec. 15.209. The radiated emissions above 960 MHz shall not exceed the
   following average limits when measured using a resolution bandwidth of 1
   MHz:

------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
960-1610..................................................         -65.3
1610-1990.................................................         -53.3
Above 1990................................................         -51.3
------------------------------------------------------------------------

   (5) In addition to the radiated emission limits specified in the table in
   paragraph (c)(4) of this section, emissions from these imaging systems shall
   not exceed the following average limits when measured using a resolution
   bandwidth of no less than 1 kHz:

------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
1164-1240.................................................         -75.3
1559-1610.................................................         -75.3
------------------------------------------------------------------------

   (d) For equipment operating with f[C] and f[M] between 1990 MHz and 10600
   MHz:

   (1) Parties operating this equipment must hold a license issued by the
   Federal Communications Commission to operate a transmitter in the Public
   Safety Radio Pool under part 90 of this chapter. The license may be held by
   the organization for which the UWB operator works on a paid or volunteer
   basis.

   (2) This equipment may be operated only for law enforcement applications,
   the providing of emergency services, and necessary training operations.

   (3) The radiated emissions at or below 960 MHz shall not exceed the emission
   levels in  Sec. 15.209 of this chapter. The radiated emissions above 960 MHz
   shall not exceed the following average limits when measured using a
   resolution bandwidth of 1 MHz:

------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
960-1610..................................................         -46.3
1610-10600................................................         -41.3
Above 10600...............................................         -51.3
------------------------------------------------------------------------

   (4) In addition to the radiated emission limits specified in the paragraph
   (d)(3) of this section, emissions from these imaging systems shall not
   exceed the following average limits when measured using a resolution
   bandwidth of no less than 1 kHz:

------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
1164-1240.................................................         -56.3
1559-1610.................................................         -56.3
------------------------------------------------------------------------

   (5) There is a limit on the peak level of the emissions contained within a
   50 MHz bandwidth centered on the frequency at which the highest radiated
   emission occurs, f[M]. That limit is 0 dBm EIRP. It is acceptable to employ
   a different resolution bandwidth, and a correspondingly different peak
   emission limit, following the procedures described in  Sec. 15.521.

   (e) Through-wall imaging systems operating under the provisions of this
   section shall bear the following or similar statement in a conspicuous
   location on the device: “Operation of this device is restricted to law
   enforcement, emergency rescue and firefighter personnel. Operation by any
   other party is a violation of 47 U.S.C. 301 and could subject the operator
   to serious legal penalties.”
