§ 25.134   Licensing provisions for Very Small Aperture Terminal (VSAT) and
C-band Small Aperture Terminal (CSAT) networks.

   (a)(1) [Reserved]

   (2) Large Networks of Small Antennas operating in the 4/6 GHz frequency
   bands.  All  applications for digital and/or analog operations will be
   routinely processed provided the network employs antennas that are 4.5 meter
   or larger in diameter, that are consistent with § 25.209, the power levels
   are consistent with § § 25.211(d) and 25.212(d), and frequency coordination
   has  been  satisfactorily  completed.  The  use of smaller antennas or
   non-consistent  power  levels  require  the  filing of an initial lead
   application (§ 25.115(c)(2)) that includes all technical analyses required to
   demonstrate that unacceptable interference will not be caused to any and all
   affected adjacent satellite operators by the operation of the non-conforming
   earth station.

   (b) VSAT networks operating in the 12/14 GHz band. An applicant for a VSAT
   network authorization proposing to operate with transmitted power spectral
   density and/or antenna input power in excess of the values specified in
   paragraph (g) of this section must comply with the requirements in § 25.220.

   (c) [Reserved]

   (d) An application for VSAT authorization shall be filed on FCC Form 312,
   Main Form and Schedule B.

   (e) VSAT networks operating in the 12/14 GHz bands may use more than one hub
   earth station, and the hubs may be sited at different locations.

   (f) 12/14 GHz VSAT operators may use temporary fixed earth stations as hub
   earth stations or remote earth stations in their networks, but must specify,
   in their license applications, the number of temporary fixed earth stations
   they plan to use.

   (g) Applications for VSAT operation in the 12/14 GHz bands that meet the
   following requirements will be routinely processed:

   (1) Equivalent antenna diameter is 1.2 meters or more and the application
   includes certification of conformance with relevant antenna performance
   standards in § 25.209 pursuant to § 25.132(a)(1).

   (2) The maximum transmitter power spectral density of a digital modulated
   carrier into any GSO FSS earth station antenna does not exceed −14.0 −
   10log(N) dB(W/4 kHz). For a VSAT network using a frequency division multiple
   access (FDMA) or a time division multiple access (TDMA) technique, N is
   equal to one. For a VSAT network using a code division multiple access
   (CDMA) technique, N is the maximum number of co-frequency simultaneously
   transmitting earth stations in the same satellite receiving beam.

   (3) The maximum GSO FSS satellite EIRP spectral density of the digital
   modulated  emission  does  not exceed 10 dB(W/4kHz) for all methods of
   modulation and accessing techniques.

   (4) Any earth station applicant filing an application to operate a VSAT
   network in the 12/14 GHz bands and planning to use a contention protocol
   must certify that its contention protocol usage will be reasonable.

   (5) The maximum transmitter power spectral density of an analog carrier into
   any GSO FSS earth station antenna does not exceed −8.0 dB(W/4kHz) and the
   maximum GSO FSS satellite EIRP spectral density does not exceed + 17.0
   dB(W/4kHz).

   (h) VSAT operators licensed pursuant to this section are prohibited from
   using remote earth stations in their networks that are not designed to stop
   transmission when synchronization to signals from the target satellite
   fails.

   Effective Date Note: At  74 FR 9962 , Mar. 9, 2009, § 25.134 paragraph (g)(4),
   which contains information collection and recordkeeping requirements, became
   effective with approval by the Office of Management and Budget for a period
   of three years.
