FCC Part 15 Radio Frequency Devices
Section 15.511

The Federal Communications Commission (FCC) is the authority in the United States of America that creates and enforces the use of airwaves throughout the entire radio frequency spectrum. This group of documents contains the entirety of the FCC Part 15 regulations that concern unlicensed radio frequency devices. As with all government documents, this material is in the public domain and may be freely copied so long as the content is not changed. This copy is provided as a convenience for RF Cafe visitors.

PART 15_RADIO FREQUENCY DEVICES--Table of Contents
 
                   Subpart F_Ultra-Wideband Operation
 
Sec. 15.511  Technical requirements for surveillance systems.
    (a) The UWB bandwidth of an imaging system operating under the 
provisions of this section must be contained between 1990 MHz and 10,600 
MHz.
    (b) Operation under the provisions of this section is limited to 
fixed surveillance systems operated by law enforcement, fire or 
emergency rescue organizations or by manufacturers licensees, petroleum 
licensees or power licensees as defined in Sec. 90.7 of this chapter.
    (1) Parties operating under the provisions of this section must be 
eligible for licensing under the provisions of part 90 of this chapter.
    (2) The operation of imaging systems under this section requires 
coordination, as detailed in Sec. 15.525.
    (c) The radiated emissions at or below 960 MHz from a device 
operating under the provisions of this section shall not exceed the 
emission levels in Sec. 15.209. The radiated emissions above 960 MHz 
from a device operating under the provisions of this section shall not 
exceed the following average limits when measured using a resolution 
bandwidth of 1 MHz:
------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
960-1610..................................................         -53.3
1610-1990.................................................         -51.3
1990-10600................................................         -41.3
Above 10600...............................................         -51.3
------------------------------------------------------------------------
[[Page 843]]
    (d) In addition to the radiated emission limits specified in the 
table in paragraph (c) of this section, UWB transmitters operating under 
the provisions of this section 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.................................................         -63.3
1559-1610.................................................         -63.3
------------------------------------------------------------------------
    (e) 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 Sec. 15.521.
    (f) 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, fire and rescue officials, public utilities, and industrial 
entities. Operation by any other party is a violation of 47 U.S.C. 301 
and could subject the operator to serious legal penalties.''
