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