Re: Sirius XM Radio Inc.
Request for 30-Day Special Temporary Authority
For a New Low Power Repeater in Arlington, Virginia

Dear Ms. Dortch:

Pursuant to Section 25.120(b)(4) of the Commission’s rules, 47 C.F.R. § 25.120(b)(4), Sirius XM
Radio Inc. (“Sirius XM”), a satellite radio licensee in the Satellite Digital Audio Radio Service
(“SDARS”), hereby requests 30-Day Special Temporary Authority (“STA”) for a new low power
terrestrial repeater with an Effective Isotropically Radiated Power (“EIRP”) of up to 2000 watts in
Arlington, Virginia.1 Specifically, this application seeks authority to operate one new low power
repeater in the former XM Radio Inc. (“XM”) frequency band (2332.5-2345 MHz). Sirius XM
requires a 30 day STA due to the landlord’s unexpected termination of the lease for the current site.
This new repeater will be co-located with an existing Sirius repeater at the same site (Sirius 46-20).

The Commission has recognized that SDARS operators require terrestrial repeaters to provide high-
quality service nationwide.2 Consistent with this policy, in September 2001, the Bureau granted
STAs to Sirius XM to operate a nationwide network of terrestrial repeaters.3 In the years since, the

Under Section 25.120(b)(4), the Commission may grant this application for a 30-Day STA
without placing it on Public Notice.

Bureau has granted Sirius XM additional STAs to operate terrestrial repeaters, pending issuance of
final rules governing the deployment and use of repeaters.4

Public Interest Considerations. Sirius XM has recently been informed by the landlord of the
current site at which this repeater is located that its equipment needs to be removed from the
location by May 31. Sirius XM currently operates a repeater on the Sirius network at a nearby site
in Arlington, Virginia and Sirius XM seeks to co-locate this repeater at the Arlington location.
Grant of the STA by May 31, 2010 will allow Sirius XM to continue providing uninterrupted
service to its subscribers in Arlington, Virginia. Without this repeater, Sirius XM cannot provide
the signal quality that its Washington, D.C. area subscribers expect.

Technical Information for the New Low Power Repeaters. The following technical information
pertaining to the repeater is provided in Exhibit A: (1) antenna type; (2) antenna orientation;
(3) average EIRP; (4) height above ground level (“AGL”); and (5) antenna downtilt.5 Exhibits B
and C consist respectively, of Google™ satellite images and topographic maps showing the location
of the proposed facilities. The specification sheet for the antenna to be used by the repeater is
attached as Exhibit D.

See, e.g., Sirius Satellite Radio Inc.; Request to Modify Special Temporary Authority to Operate
Additional Satellite Digital Audio Radio Service Terrestrial Repeaters, Order and
Authorization, 19 FCC Rcd. 18140 (2004) (granting Sirius an STA in File No. SAT-STA-
20031106-00370, effective Sept. 15, 2004. Since that time, the Commission has extended the
STA several times, pending the issuance of final rules governing the use of satellite DARS
terrestrial repeaters. In September 2004, the Commission granted Sirius a new STA to operate
for 180 days or until the Commission issues final rules governing the use of satellite DARS
terrestrial repeaters. See Sirius Satellite Radio Inc. Request to Modify Special Temporary
Authority to Operate Satellite DARS Terrestrial Repeaters, Order and Authorization, 19 FCC
Rcd 18149 (2004) (“2004 STA Grant Order”). Sirius timely filed an application for renewal of
this STA on March 1, 2005. See File No. SAT-STA-20050301-00053. To date, the
Commission has not acted on this application. See also, XM Radio, Inc.; Request for Special
Temporary Authority to Operate Additional Satellite Digital Audio Radio Service Terrestrial
Repeaters, Order and Authorization, 19 FCC Rcd. 18140 (2004) (granting XM an STA in File
No. SAT-STA-20031112-00371, effective Sept. 15, 2004); Public Notice, 2002 FCC Lexis
5670 (rel. Oct. 30, 2002) (granting XM an STA in File No. SAT-STA-20020815-00153,
effective Sept. 30, 2002); Public Notice, 2003 FCC Lexis 4803 (rel. Aug. 29, 2002) (granting
XM an STA in File No. SAT-STA-20030409-00076, effective June 26, 2003). XM has filed
applications to renew its STAs, and those renewal applications remain pending.

For purposes of Sirius XM’s repeater STA applications, “antenna downtilt” refers to an
antenna’s mechanical downtilt, without reference to any electrical downtilt built into the
antenna.

Interference Considerations. As proposed in this STA, the repeater will operate at an average EIRP
of less than 2000 watts. Because Sirius XM has exclusive use of its licensed band, it is highly
unlikely that this low power repeater will create interference to other licensees. To the extent Sirius
XM’s original 2001 STAs require it to coordinate with affected Wireless Communications Services
(“WCS”) licensees prior to operating any repeater, Sirius XM is sending a copy of this STA
application to Horizon Wi-Com LLC (“Horizon”) in satisfaction of this coordination requirement.6
Moreover, as the Bureau acknowledged in granting Sirius XM’s original repeater STA requests, the
WCS licensees have confirmed that operating terrestrial repeaters at an EIRP of 2 kW or less is not
an interference concern.7 However, if prohibited interference does occur, Sirius XM will cease
operation of the repeater until such interference can be eliminated.8

Ownership and Control of Repeaters. Sirius XM will own the repeater and it will be responsible
for the repeater’s installation and operation.

6
Despite the Bureau’s statement in the XM STA Order (at ¶ 14) and Sirius STA Order (at ¶ 14)
that it expects “WCS licensees to provide a schedule or as much advance notice as possible of
when their stations are to be placed in operation,” Sirius XM has not received information
directly from any WCS licensee regarding plans for WCS deployment in these markets.
However, Sirius XM’s own review of Commission files shows that Horizon has certified that it
operates a WCS station serving the Washington, DC metro area, Call Sign KNLB315. It is not
clear from the certification whether the base station is receiving transmissions from CPE or is
engaged in transmit-only operations. If only the latter, potential interference to the base station
is not an issue. In any event, Sirius XM has conducted an interference analysis and determined
that its proposed repeaters will not create any interference concern for Horizon’s operating
WCS site beyond any concerns that may exist from Sirius XM’s existing repeaters in the
vicinity, none of which have been the subject of any interference complaints from WCS
licensees or users.

XM STA Order ¶ 12 (“The comments from WCS licensees express concern about blanketing
interference from DARS repeaters that operate with an Equivalent Isotropically Radiated Power
(EIRP) above 2 kW.”). Moreover, in March 2007, the WCS Coalition said that it will defer
from objecting to STA requests that propose operations of no more than 2,000 watts EIRP, even
if they do not specify peak or average EIRP, provided that grant of the STA (i) is conditioned
on operation on a non-interference basis; and (ii) is subject to the condition that the issue of
peak versus average EIRP will be addressed in the pending DARS rulemaking (IB Docket No.
95-91). See Letter from Paul J. Sinderbrand, Counsel to the WCS Coalition, to Ms. Helen
Domenici, FCC, File No. SAT-STA-20061207-00145 (March 19, 2007). XM agrees to these
conditions.

This repeater’s design includes several automated shutdown mechanisms that are triggered in
the event of equipment major malfunctions. The transmit chain also includes a transmit output
coupler which feeds a self-monitoring system detecting any transmission anomalies. Any such
anomalies are automatically reported back to Sirius XM’s National Repeater Control Center
(202-380-4725), which is available on a continuous basis to receive any reports of any
suspected interference and take immediate corrective action.
