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."
