                   Subpart B_Applications and Licenses

 

Sec. 25.134  Licensing provisions of Very Small Aperture Terminal (VSAT) 

and C-band Small Aperture Terminal (CSAT) networks.



    (a)(1) VSAT networks operating in the 12/14 GHz bands. All 

applications for digital VSAT networks with a maximum outbound downlink 

EIRP density of +6.0 dBW/4 kHz per carrier and earth station antennas 

with maximum input power density of -14 dBW/4 kHz and maximum hub EIRP 

of 78.3 dBW will be processed routinely. All applications for analog 

VSAT networks with maximum outbound downlink power densities of +13.0 

dBW/4 kHz per carrier and maximum antenna input power densities of -8.0 

dBW/4 kHz shall be processed routinely in accordance with Declaratory 

Order in the Matter of Routine Licensing of Earth Stations in the 6 GHz 

and 14 GHz Bands Using Antennas Less than 9 Meters and 5 Meters in 

Diameter, Respectively, for Both Full Transponder and Narrowband 

Transmissions, 2 FCC Rcd 2149 (1987) (Declaratory Order).

    (a)(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 Sec. 

25.209, the power levels are consistent with Sec. Sec. 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 (Sec. 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 bands. Each applicant 

for digital and/or analog VSAT network authorization proposing to use 

transmitted satellite carrier EIRP densities in excess of +6.0 dBW/4 kHz 

and +13.0 dBW/4 kHz, respectively, and/or maximum antenna input power 

densities of -14.0 dBW/4 kHz and maximum hub EIRPs of 78.3 dBW and -8.0 

dBW/4 kHz per carrier, respectively, shall conduct an engineering 

analysis using the Sharp, Adjacent Satellite Interference Analysis 

(ASIA) program. Applicants shall submit a complete description of those 

baseline parameters they use in conducting their analysis and tabular 

summaries of the ASIA program's output detailing potential interference 

shortfalls. Applicants shall also submit a narrative summary which must 

indicate whether there are margin shortfalls in any of the current 

baseline services as a result of the addition of the new applicant's 

high power service, and if so, how the applicant intends to resolve 

those margin shortfalls. Applicants shall submit link budget analyses of 

the operations proposed along with a detailed written explanation of how 

each uplink and each transmitted satellite carrier density figure is 

derived. Applicants shall provide proof by affidavit that all 

potentially affected parties acknowledge and do not object to the use of 

the applicant's higher power density.

    (c) Licensees authorized pursuant to paragraph (b) of this section 

shall bear the burden of coordinating with any future applicants or 

licensees whose proposed compliant VSAT operations, as defined by 

paragraph (a) of this section, is potentially or actually adversely 

affected by the operation of the

non-compliant licensee. If no good faith agreement can be reached, 

however, the non-compliant licensee shall reduce its power density 

levels to those compliant with the VSAT Order or the Declaratory Order, 

whichever is applicable.

    (d) An application for VSAT authorization shall be filed on FCC Form 

312, Main Form and Schedule B. A VSAT licensee applying to renew its 

license must include on FCC Form 405, the number of constructed VSAT 

units in its network.
