§ 25.263 Information sharing requirements for SDARS terrestrial repeater
operators.
This section requires SDARS licensees in the 2320-2345 MHz band to
share information regarding the location and operation of terrestrial
repeaters with WCS licensees in the 2305-2320 MHz and 2345-2360 MHz
bands. Section 27.72 of this chapter requires WCS licensees to share
information regarding the location and operation of base stations in
the 2305-2320 MHz and 2345-2360 MHz bands with SDARS licensees in the
2320-2345 MHz band.
(a) SDARS licensees must select terrestrial repeater sites and
frequencies, to the extent practicable, to minimize the possibility of
harmful interference to WCS base station operations in the 2305-2320
MHz and 2345-2360 MHz bands.
(b) Notice requirements. SDARS licensees that intend to operate a new
terrestrial repeater must, before commencing such operation, provide 10
business days prior notice to all potentially affected Wireless
Communications Service (WCS) licensees. SDARS licensees that intend to
modify an existing repeater must, before commencing such modified
operation, provide 5 business days prior notice to all potentially
affected WCS licensees.
(1) For purposes of this section, a “potentially affected WCS licensee”
is a WCS licensee that:
(i) Is authorized to operate a base station in the 2305-2315 MHz or
2350-2360 MHz bands in the same Major Economic Area (MEA) as that in
which the terrestrial repeater is to be located;
(ii) Is authorized to operate base station in the 2315-2320 MHz or
2345-2350 MHz bands in the same Regional Economic Area Grouping (REAG)
as that in which the terrestrial repeater is to be located;
(iii) In addition to the WCS licensees identified in paragraphs
(b)(1)(i) and (ii) of this section, in cases in which the SDARS
licensee plans to deploy or modify a terrestrial repeater within 5
kilometers of the boundary of an MEA or REAG in which the terrestrial
repeater is to be located, a potentially affected WCS licensee is one
that is authorized to operate a WCS base station in that neighboring
MEA or REAG within 5 kilometers of the location of the terrestrial
repeater.
(2) For the purposes of this section, a business day is defined by
§ 1.4(e)(2) of this chapter.
(3) For modifications other than changes in location, a licensee may
provide notice within 24 hours after the modified operation if the
modification does not result in a predicted increase of the power flux
density (PFD) at ground level by more than 1 dB since the last advance
notice was given. If a demonstration is made by the WCS licensee that
such modifications may cause harmful interference to WCS receivers,
SDARS licensees will be required to provide notice 5 business days in
advance of additional repeater modifications.
(4) SDARS repeaters operating below 2 watts equivalent isotropically
radiated power (EIRP) are exempt from the notice requirements set forth
in this paragraph.
(5) SDARS licensees are encouraged to develop separate coordination
agreements with WCS licensees to facilitate efficient deployment of and
coexistence between each service. To the extent the provisions of any
such coordination agreement conflict with the requirements set forth
herein, the procedures established under a coordination agreement will
control. SDARS licensees must maintain a copy of any coordination
agreement with a WCS license in their station files and disclose it to
prospective assignees, transferees, or spectrum lessees and, upon
request, to the Commission.
(6) SDARS and WCS licensees may enter into agreements regarding
alternative notification procedures.
(c) Contents of notice. (1) Notification must be written (e.g.,
certified letter, fax, or e-mail) and include the licensee's name, and
the name, address, and telephone number of its coordination
representative, unless the SDARS licensee and all potentially affected
WCS licensees reach a mutual agreement to provide notification by some
other means. WCS licensees and SDARS licensees may establish such a
mutually agreeable alternative notification mechanism without prior
Commission approval, provided that they comply with all other
requirements of this section.
(2) Regardless of the notification method, notification must specify
relevant technical details, including, at a minimum:
(i) The coordinates of the proposed repeater to an accuracy of no less
than ±1 second latitude and longitude;
(ii) The proposed operating power(s), frequency band(s), and
emission(s);
(iii) The antenna center height above ground and ground elevation above
mean sea level, both to an accuracy of no less than ±1 meter;
(iv) The antenna gain pattern(s) in the azimuth and elevation planes
that include the peak of the main beam; and
(v) The antenna downtilt angle(s).
(3) An SDARS licensee operating terrestrial repeaters must maintain an
accurate and up-to-date inventory of its terrestrial repeaters
operating above 2 watts average EIRP, including the information set
forth in § 25.263(c)(2), which shall be available upon request by the
Commission.
(d) Calculation of Notice Period. Notice periods are calculated from
the date of receipt by the licensee being notified. If notification is
by mail, the date of receipt is evidenced by the return receipt on
certified mail. If notification is by fax, the date of receipt is
evidenced by the notifying party's fax transmission confirmation log.
If notification is by e-mail, the date of receipt is evidenced by a
return e-mail receipt. If the SDARS licensee and all potentially
affected WCS licensees reach a mutual agreement to provide notification
by some other means, that agreement must specify the method for
determining the beginning of the notice period.
(e) Duty to cooperate. SDARS licensees must cooperate in good faith in
the selection and use of new repeater sites to reduce interference and
make the most effective use of the authorized facilities. SDARS
licensees should provide WCS licensees as much lead time as practicable
to provide ample time to conduct analyses and opportunity for prudent
repeater site selection prior to SDARS licensees entering into real
estate and tower leasing or purchasing agreements. Licensees of
stations suffering or causing harmful interference must cooperate in
good faith and resolve such problems by mutually satisfactory
arrangements. If the licensees are unable to do so, the International
Bureau, in consultation with the Office of Engineering and Technology
and the Wireless Telecommunications Bureau, will consider the actions
taken by the parties to mitigate the risk of and remedy any alleged
interference. In determining the appropriate action, the Bureau will
take into account the nature and extent of the interference and act
promptly to remedy the interference. The Bureau may impose restrictions
on SDARS licensees, including specifying the transmitter power, antenna
height, or other technical or operational measures to remedy the
interference, and will take into account previous measures by the
licensees to mitigate the risk of interference.
