§  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 §  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       39DEG08'10'' N 121DEG21'04'' W
   Cape Cod Air Force Station 41DEG45'07'' N 070DEG32'17'' W
   Clear Air Force Station    64DEG55'16'' N 143DEG05'02'' W
   Cavalier Air Force Station 48DEG43'12'' N 097DEG54'00'' W
   Eglin Air Force Base       30DEG43'12'' N 086DEG12'36'' 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.
