Sec.  15.240   Operation in the band 433.5–434.5 MHz.

   (a) Operation under the provisions of this section is restricted to devices
   that use radio frequency energy to identify the contents of commercial
   shipping containers. Operations must be limited to commercial and industrial
   areas such as ports, rail terminals and warehouses. Two-way operation is
   permitted to interrogate and to load data into devices. Devices operated
   pursuant to the provisions of this section shall not be used for voice
   communications.

   (b)  The field strength of any emissions radiated within the specified
   frequency band shall not exceed 11,000 microvolts per meter measured at a
   distance of 3 meters. The emission limit in this paragraph is based on
   measurement instrumentation employing an average detector. The peak level of
   any emissions within the specified frequency band shall not exceed 55,000
   microvolts per meter measured at a distance of 3 meters. Additionally,
   devices authorized under these provisions shall be provided with a means for
   automatically limiting operation so that the duration of each transmission
   shall not be greater than 60 seconds and be only permitted to reinitiate an
   interrogation  in  the  case  of  a  transmission error. Absent such a
   transmission error, the silent period between transmissions shall not be
   less than 10 seconds.

   (c) The field strength of emissions radiated on any frequency outside of the
   specified band shall not exceed the general radiated emission limits in
    Sec. 15.209.

   (d) In the case of radio frequency powered tags designed to operate with a
   device authorized under this section, the tag may be approved with the
   device  or  be  considered  as  a  separate  device subject to its own
   authorization.  Powered  tags  approved  with  a device under a single
   application shall be labeled with the same identification number as the
   device.

   (e) To prevent interference to Federal Government radar systems, operation
   under the provisions of this section is not permitted within 40 kilometers
   of the following locations:
         DoD Radar Site        Latitude    Longitude
   Beale Air Force Base       39 °08'10" N 121 °21'04" W
   Cape Cod Air Force Station 41 °45'07" N 070 °32'17" W
   Clear Air Force Station    64 °55'16" N 143 °05'02" W
   Cavalier Air Force Station 48 °43'12" N 097 °54'00" W
   Eglin Air Force Base       30 °43'12" N 086 °12'36" W

   (f) As a condition of the grant, the grantee of an equipment authorization
   for a device operating under the provisions of this section shall provide
   information  to  the  user  concerning compliance with the operational
   restrictions  in  paragraphs (a) and (e) of this section. As a further
   condition, the grantee shall provide information on the locations where the
   devices are installed to the FCC Office of Engineering and Technology, which
   shall  provide  this information to the Federal Government through the
   National Telecommunications and Information Administration. The user of the
   device shall be responsible for submitting updated information in the event
   the  operating location or other information changes after the initial
   registration. The grantee shall notify the user of this requirement. The
   information provided by the grantee or user to the Commission shall include
   the name, address, telephone number and e-mail address of the user, the
   address and geographic coordinates of the operating location, and the FCC
   identification number of the device. The material shall be submitted to the
   following address:

   Experimental Licensing Branch, OET, Federal Communications Commission, 445
   12th Street, SW., Washington, DC 20554, ATTN: RFID Registration.
