                                            Exhibit A

                                   Description of Application

        ViaSat, Inc. (“ViaSat”) seeks blanket authority to operate 4,000,000 electrically identical
earth station antennas to communicate with the VIASAT-1 satellite, utilizing the 28.35-29.1 GHz
and 29.5-30.0 GHz (uplink) bands and the 18.3-19.3 GHz and 19.7-20.2 GHz (downlink) bands.
To the extent necessary, ViaSat requests a waiver1 of the Commission’s rule for geostationary
orbit (“GSO”) fixed satellite service (“FSS”) earth station blanket licensing2 to permit
widespread deployment of its ground terminals utilizing the 28.6-29.1 GHz and 18.8-19.3 GHz
bands. VIASAT-1 is authorized to serve the U.S. in these bands and is scheduled for launch in
the spring of 2011.

                 Blanket licensing of earth station terminals operating in the 28.6-29.1 GHz and
18.8-19.3 GHz bands will expedite and lower the cost of deployment of satellite broadband
service to consumers. The broadband service that ViaSat will offer using VIASAT-1 promises
to be a critical solution to the Commission’s universal broadband service goals. VIASAT-1 will
be capable of serving 1.5 to 2 million subscribers at the 4/1 Mbit/s universal speed goal
established in the National Broadband Plan. Having to submit applications (even streamlined
proposals) to deploy service to meet the needs of these subscribers would significantly delay
deployment and would increase the cost of service. As discussed in further detail below, NGSO
system operations that are primary in the U.S. in these bands will be protected from harmful
interference by the capabilities built into ViaSat’s satellite network. Therefore, a site-by-site
compatibility demonstration is unnecessary. Given the pressing public interest in deploying 4/1
Mbit/s broadband to unserved areas, flexibility in processing is warranted. With the upcoming
scheduled launch of VIASAT-1 in the spring of 2011, a blanket licensing approach would
provide certainty that consumers will have access to broadband service from VIASAT-1 soon
after the completion of in-orbit testing.

Compatibility with GSO, NGSO and Terrestrial Users

                 The proposed earth station antennas will communicate with the VIASAT-1
satellite at the nominal 115º W.L. location using the 18.3-19.3 GHz, 19.7-20.2 GHz, 28.35-29.1
GHz and 29.5-30.0 GHz segments of the Ka band for which VIASAT-1 is already authorized.
The proposed operation of these antennas will not cause harmful interference to adjacent GSO
systems, NGSO systems or any primary terrestrial users in these bands.

                The proposed earth station terminal conforms to the antenna performance
standards in Section 25.209, as demonstrated by the antenna gain patterns attached hereto as
Exhibit B. The antenna also meets the performance requirements in Section 25.138(a), as
illustrated by the off-axis EIRP spectral density plots attached hereto as Exhibit C. Although the
antenna reflector is slightly elliptical in shape, from an RF perspective, the antenna beam is

almost circular. As illustrated by the attached antenna patterns, the minor axis off-axis emissions
comply with Section 25.138 levels for the major axis. Therefore, the major axis of the antennas
will be effectively aligned with the geostationary satellite orbit, consistent with requirement in
Section 25.209(a)(5). In addition, the power flux-density at the earth’s surface produced by
emissions from the satellite points of communication are within the -118 dBW/m2/MHz limit set
forth in Section 25.138(a)(6). Therefore, the antenna type does not require coordination with
adjacent GSO satellites.

                 Furthermore, pursuant to the terms of the Commission’s authorization of
VIASAT-1, operation of the GSO FSS system in the 28.6-29.1 GHz band is on a secondary
allocation, and in the 18.8-19.3 GHz band is on a non-conforming basis.3 The Commission has
approved operation of the VIASAT-1 satellite in these bands, and has acknowledged that ViaSat
can operate in these bands while protecting the primary NGSO FSS operations.4 Specifically,
the satellite has been designed with the capability to cease operations in the 18.8-19.3 GHz
downlink band and the associated 28.6-29.1 GHz uplink band in any spot beams where the
predicted physical alignment of either (i) the VIASAT-1 satellite and an earth station
communicating with an NGSO space station, or (ii) a NGSO space station and an earth station
communicating with the VIASAT-1 satellite, is such that the angular separation between
operational links of the two satellite networks would be equal to or less than a specified
minimum line-of-sight separation angle. In that case, and for the short duration of the event, the
affected VIASAT-1 satellite spot beam will continue providing service in other authorized
bands. Therefore, operation of the proposed antennas will not cause harmful interference into
NGSO systems.

                Finally, when the Commission adopted allocations for the Ka-band, it established
sunset provisions for the co-primary status of certain terrestrial users in the FSS downlink bands
in order to protect and facilitate deployment of FSS operations.5 ViaSat acknowledges that
terrestrial microwave users maintain co-primary status with NGSO FSS in the 19.26-19.3 GHz
until October 31, 2011.6 Accordingly, until that date, ViaSat will protect these users and will not
seek protection from interference from such users. Additionally, terrestrial microwave users
maintain co-primary status in the 18.3-18.58 GHz band until November 18, 2012.7 In
accordance with the blanket licensing rules, no coordination with terrestrial or other users is
required on the GSO frequencies. ViaSat may either accept any potential for interference from

potential for interference from such users until the relevant date.

Blanket Licensing of GSO Terminals is Warranted in the 28.6-29.1 GHz and 18.8-19.3 GHz
Bands

                Section 25.138 permits blanket licensing and provides streamlined processing
procedures for earth station antennas operating in the 18.3-18.8 GHz, 19.7-20.2 GHz, 28.35-28.6
GHz, 29.25-29.5 GHz and 29.5-30.0 GHz bands, provided that the technical criteria set forth in
that section are met. However, no blanket licensing rules have been adopted yet for the 18.8-
19.3 GHz and 28.6-29.1 GHz bands.8 ViaSat requests that the Commission employ blanket
licensing of ViaSat’s proposed earth station antennas in the 28.6-29.1 GHz and 18.8-19.3 GHz
bands rather than using a site-by-site licensing process. Given the large number of terminals
requested and the network-wide implementation of technology that is capable of operating
without interfering with primary NGSO operators, requiring the filing of individual applications
for each terminal would be unduly burdensome and unnecessary.

                 The Commission has implemented blanket licensing procedures on a case-by-case
basis (outside of a rulemaking or other broadly-applicable proceeding) where circumstances have
warranted such an approach. For instance, the Commission granted blanket authority for an
earth station fleet prior to the adoption of the Ku band blanket licensing rules in a scenario where
significant burdens would have resulted if the prospective licensee were required to submit, and
the Commission were required to process, hundreds of individual license requests.9 In that case,
the Commission did not require individual license applications for 500 identical terminals
because the Commission imposed a condition requiring the licensee to maintain accurate data on
the locations of its stations at a point of contact through which each station could be contacted
and controlled.10

                The Commission’s policy justifications underlying its adoption of blanket earth
station licensing procedures in rulemaking proceedings and declaratory rulings are equally
applicable to the subject application. Allowing processing flexibility in this case will promote
the expanded use of spectrum and the rapid development and deployment of new technologies.11
Such an approach serves the public interest by reducing administrative costs and delays and by
accelerating system deployment, which facilitates the delivery of service to end users.12 Blanket
licensing of the proposed terminals in the 28.6-29.1 GHz and 18.8-19.3 GHz bands will speed
the delivery of 4/1 Mbit/s broadband service to the millions of unserved consumers identified in
the National Broadband Plan. Therefore, flexibility in processing this application is warranted.

                 Further, ViaSat previously demonstrated that communications between
VIASAT-1 and ViaSat’s network of earth terminals would not interfere with any primary NGSO
operations currently planned or authorized in the future. As described above, VIASAT-1 is
designed with the capability to cease operations in the 18.8-19.3 GHz and 28.6-29.1 GHz bands
upon receipt of appropriate ground command signals. This technology is capable of preventing
harmful interference into NGSO systems from any earth station terminal deployed in the
satellite’s area of operation. Each of the proposed terminals covered by this application will be
dynamically controlled and can shut down operations in the bands in which NGSO systems have
priority when an NGSO satellite is within the minimum line-of-sight separation angle established
through coordination. Blanket licensing in these shared frequency bands is warranted in light of
the network-wide demonstration that any and all earth station terminals in the network can
operate without causing interference to primary NGSO users.

Radiation Hazard Analysis

                A radiation hazard analysis for the proposed antenna is attached hereto as
Exhibit D. As demonstrated by the results of the analysis, the maximum permissible exposure
limit (MPE) for protection of the General Population/Uncontrolled Exposures – 1 mW/cm2
averaged over a thirty minute period – is met. The automatic shut-down capabilities described in
the analysis, coupled with the terminal’s use of uplink power control and non-continuous
operation, ensures that the general population will not be exposed to harmful levels of
electromagnetic radiation.
