§ 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, fC, and the
frequency at which the highest radiated emission occurs, fM, 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 § 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 § 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 fC and fM 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 § 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, fM. 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 § 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.”
