NARRATIVE STATEMENT

Pursuant to Section 5.3 and Section 5.61 of the Commission’s rules, 47 C.F.R. §§ 5.3, 5.61,
LightSquared Subsidiary LLC, Debtor-in-Possession (“LightSquared”) respectfully requests
special temporary authority (“STA”) for a four-month period, commencing as soon as possible,
for the purpose of ascertaining (i) the technical compatibility of fixed commercial wireless base
stations in the 1675-1680 MHz band with existing spectrum operations in and around that
frequency range, and (ii) the technical compatibility of radiosonde operations in the 400.15-406
MHz band with existing spectrum operations in and around that frequency range.

2. Description of Operations and Purpose of Assessment.

LightSquared is a satellite service provider in the L Band, and also holds Commission authority
to conduct certain 4G LTE terrestrial wireless operations in that spectrum. LightSquared has
proposed to conduct a portion of those terrestrial operations in the 1670-1680 MHz band. 1

LightSquared currently has authority to use the 1670-1675 MHz band for terrestrial operations
nationwide. The 1675-1680 MHz band, however, currently is allocated on a primary basis for
both non-Federal and Federal use by Meteorological Aids (e.g. radiosondes) and the
Meteorological-Satellite Service (e.g., MetSats, like the GOES system). Continued use of this
band by radiosondes may not be compatible with the expected operation of the new GOES-R
satellite system that is expected to be deployed in the next few years. 2

1
LightSquared’s September 28, 2012 license modification applications (the “License
Modification Applications”) provide a comprehensive solution to the issues that have
precluded the deployment of its terrestrial wireless network, and include a proposal to
permanently relinquish its authority to conduct terrestrial downlinks in the L Band at
1545-1555 MHz and, in lieu thereof, conduct them at 1670-1680 MHz. See IBFS File
Nos. SAT-MOD-20120928-00160, SAT-MOD-20120928-00161, and SES-MOD-
20121001-00872; see also Public Notice: FCC Invites Comment on LightSquared
Request to Modify its ATC Authorization, DA 12-1863, IB Docket No. 12-340 (Nov. 16,
2012).

The proposed assessment will examine the technical feasibility of operating fixed commercial
wireless base stations at 1675-1680 MHz, with or without also relocating radiosonde operations
in the U.S. from 1675-1680 MHz to 400.15-406 MHz (which is internationally harmonized for
radiosonde operations). This assessment will take into account existing spectrum operations in
and around those frequency ranges, and ascertain commercial operating parameters that are
needed to protect critical federal operations, including the continued, uninterrupted nature of
NOAA’s vital meteorological mission.

The proposed assessment will involve the procurement, deployment and operation of terrestrial
radio transmitters at fixed locations in the 1675-1680 MHz band (and also in the 1670-1675
MHz band to which LightSquared already has leased spectrum rights). LightSquared will
coordinate the deployment and operation of those radio transmitters at those locations in advance
with the FCC and NTIA, as may be required, including the frequencies and power levels used.

The proposed assessment also may involve the procurement, deployment and operation of
radiosonde transmitters in the atmosphere in the 400.15-406 MHz band. LightSquared similarly
will coordinate the deployment and operation of those radiosondes in advance with the FCC and
NTIA, as may be required, including the frequencies and power levels used.

LightSquared will bear the cost of procuring, deploying and operating this equipment, and of
contracting for conducting the proposed assessment through an entity that is acceptable to NTIA
and NOAA.

LightSquared will (i) work in cooperation with the FCC, NTIA, NOAA, and other interested
federal agencies to develop specific assessment plans, including identifying the specific locations
for the deployment of terrestrial radios and the salient operating parameters, (ii) allow
representatives of those federal agencies to observe and participate in the assessment, and (iii)
make any reports available to those federal agencies.

3. Public Interest Basis for STA.

Timely grant of STA would enable LightSquared to commence the assessment as soon as
possible, and thus gather data that can be used to advance a number of important policy goals.

The 1675-1680 MHz band is part of the spectrum that (i) NTIA (in consultation with the FCC)
already has identified as potentially available for wireless broadband use, and as warranting
further evaluation, 3 and (ii) LightSquared has proposed as part of the License Modification
Applications to use for its fixed wireless base stations (in lieu of the 1545-1555 MHz portion of
the L Band). See LightSquared Subsidiary LLC Request for Relief from Build-Out Conditions,

DA 12-2051, IB Docket No. 12-296, at ¶ ¶ 12, 13 (2012) (“[W]e find that it is in the public
interest to provide for an orderly deliberative process in which LightSquared will have the
opportunity to explore solutions to GPS interference concerns”).

Moreover, grant of this STA will enable the gathering of data that will facilitate the modification
of current radiosonde operations in and around the 1675-1680 MHz band that is required by the
“downshift” of a portion of the GOES-R satellite downlink channels. 4 Additionally, it will
facilitate an assessment of the cost of potentially relocating radiosondes to the 400 MHz band,
which would then inform an eventual determination of an appropriate vehicle for meeting these
costs.

For these reasons, expeditious grant of this STA would serve the public interest, convenience,
and necessity by enabling LightSquared to gather on timely basis data that will facilitate the
assessment of these types of issues by the FCC, NTIA, and other federal agencies. See 47 C.F.R.
§ 5.61(a).

4. Dates of Operation.

LightSquared requests STA for four months, commencing as soon as possible. 5 LightSquared
anticipates the proposed assessment will take from two to four months.

5. Classes of Stations.

LightSquared proposes to operate (i) wireless base stations at fixed terrestrial locations in the
1675-1680 MHz band (and also in the 1670-1675 MHz band to which LightSquared has leased
spectrum rights), and (ii) radiosondes in the atmosphere in the 400.15-406 MHz band.

6. Location of Proposed Operations.

LightSquared requests authority to conduct the proposed assessment throughout the continental
United States. As noted above, LightSquared will coordinate the deployment and operation of its
RF transmitters in advance with the FCC and NTIA, as may be required.

The terrestrial radios currently are expected to be located within a 6 to 25 km radius of Wallops
Island, VA and Suitland, MD, at sites with the following characteristics:

Accommodating Wireless Broadband Systems in the 1675-1710 MHz, 1755-1780 MHz,
3500-3650 MHz, and 4200-4220 MHz, 4380-4400 MHz Bands, at 1-6 (Oct. 2010).
5
Because the STA Application Form requires an applicant to specify a “start date “and an
“end date” for the requested authorization, LightSquared has done so. However,
LightSquared recognizes that the Commission may not have processed the application
fully by the specified “start date.” As discussed above, LightSquared simply seeks STA
for four months, commencing as soon as possible.

Two sites for each such geographic area have been selected for contingency purposes.
Additional assessments may be needed in other geographic areas as well, subject to coordination
with the FCC, NTIA, NOAA, and other interested federal agencies.

For each location of a terrestrial radio, LightSquared will provide a “Stop Buzzer” name and
phone number for that specific location as part of the federal coordination process.

LightSquared will cease operations of any particular activity if the FCC or NTIA (or another
designated agency) provides LightSquared with notice of suspected interference and will not
recommence that such activity until the FCC authorizes the recommencement of that activity.

7. Equipment To Be Used.

LightSquared will employ reliable methods to simulate 4G LTE wireless base station emissions
operating in the 1675-1680 MHz band, including assembling the required signal generators, high
powered amplifiers, RF transmit filters and the necessary antennas (e.g., Argus HPX308R,
TongYu TDJ151717DE-65, Agilent 4438C, ComTech ARD88259-50). In the 400.15-406 MHz
band, LightSquared will make use of Sippican Mark II Microsonde radiosondes and associated
telemetry equipment, and potentially also will make use of radiosonde equipment manufactured
by Vaisala. As part of the coordination process with the FCC, NTIA, and other agencies,
LightSquared will make available the technical specifications of all RF equipment used in its
assessment under this STA.

8. Frequencies Desired.

LightSquared requests operating authority at 1675-1680 MHz (for fixed base station operations),
and at 400.15-406 MHz for radiosondes.

9. Power Levels.

For the 1675-1680 MHz band: 1585 W is the maximum transmitter power output including
antenna gain.

For the 400.15-406 MHz band: 380 mW is the maximum transmitter power output including
antenna gain. Devices will be compliant with ITU RS.1165-2 for Type B digital transmitters and
thus transmit power will typically be less than the quoted maximum.

12. Overall Height of Antenna(s) Above Ground.

Base station heights will be lower than 200 meters and may be placed at existing LightSquared
or industry partner base station locations to facilitate compliance with FAA requirements.

Radiosondes will be operated in the atmosphere, at heights of approximately 3-100,000 feet.
