§ 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.
