§ 25.149 Application requirements for ancillary terrestrial components in
the mobile-satellite service networks operating in the 1.5./1.6 GHz, 1.6/2.4
GHz and 2 GHz mobile-satellite service.
(a) Applicants for ancillary terrestrial component authority shall
demonstrate that the applicant does or will comply with the following
through certification or explanatory technical exhibit, as appropriate:
(1) ATC shall be deployed in the forward-band mode of operation whereby
the ATC mobile terminals transmit in the MSS uplink bands and the ATC
base stations transmit in the MSS downlink bands in portions of the
2000-2020 MHz/2180-2200 MHz bands (2 GHz band), the 1626.5-1660.5
MHz/1525-1559 MHz bands (L-band), and the 1610-1626.5 MHz/2483.5-2500
MHz bands (Big LEO band).
Note to paragraph (a)(1): An L-band MSS licensee is permitted to apply
for ATC authorization based on a non-forward-band mode of operation
provided it is able to demonstrate that the use of a non-forward-band
mode of operation would produce no greater potential interference than
that produced as a result of implementing the rules of this section.
(2) ATC operations shall be limited to certain frequencies:
(i) In the 2000-2020 MHz/2180-2200 MHz bands (2 GHz MSS band), ATC
operations are limited to the selected assignment of the 2 GHz MSS
licensee that seeks ATC authority.
(ii) In the 1626.5-1660.5 MHz/1525-1559 MHz bands (L-band), ATC
operations are limited to the frequency assignments authorized and
internationally coordinated for the MSS system of the MSS licensee that
seeks ATC authority.
(iii) In the 1610-1626.5 MHz/2483.5-2500 MHz bands (Big LEO bands), ATC
operations are limited to the 1610-1617.775 MHz, 1621.35-1626.5 MHz,
and 2483.5-2495 MHz bands and to the specific frequencies authorized
for use by the MSS licensee that seeks ATC authority.
(3) ATC operations shall not exceed the geographical coverage area of
the mobile satellite service network of the applicant for ATC
authority.
(4) ATC base stations shall comply with all applicable antenna and
structural clearance requirements established in part 17 of this
chapter.
(5) ATC base stations and mobile terminals shall comply with part 1 of
this chapter, Subpart I--Procedures Implementing the National
Environmental Policy Act of 1969, including the guidelines for human
exposure to radio frequency electromagnetic fields as defined in
§ § 1.1307(b) and 1.1310 of this chapter for PCS networks.
(6) ATC base station operations shall use less than all available MSS
frequencies when using all available frequencies for ATC base station
operations would exclude otherwise available signals from MSS
space-stations.
(b) Applicants for an ancillary terrestrial component shall demonstrate
that the applicant does or will comply with the following criteria
through certification:
(1) Geographic and temporal coverage. (i) For the 2 GHz MSS band, an
applicant must demonstrate that it can provide space-segment service
covering all 50 states, Puerto Rico, and the U.S. Virgin Islands
one-hundred percent of the time, unless it is not technically possible,
consistent with the coverage requirements for 2 GHz MSS GSO operators.
(ii) For the L-band, an applicant must demonstrate that it can provide
space-segment service covering all 50 states, Puerto Rico, and the U.S.
Virgin Islands one-hundred percent of the time, unless it is not
technically possible for the MSS operator to meet the coverage criteria
from its orbital position.
(iii) For the Big LEO band, an applicant must demonstrate that it can
provide space-segment service to all locations as far north as 70DEG
North latitude and as far south as 55DEG South latitude for at least
seventy-five percent of every 24-hour period, i.e. , that at least one
satellite will be visible above the horizon at an elevation angle of at
least 5DEG for at least 18 hours each day, and on a continuous basis
throughout the fifty states, Puerto Rico and the U.S. Virgin Islands,
i.e. , that at least one satellite will be visible above the horizon at
an elevation angle of at least 5DEG at all times.
(2) Replacement satellites. (i) Operational NGSO MSS ATC systems shall
maintain an in-orbit spare satellite.
(ii) Operational GSO MSS ATC systems shall maintain a spare satellite
on the ground within one year of commencing operations and launch it
into orbit during the next commercially reasonable launch window
following a satellite failure.
(iii) All MSS ATC licensees must report any satellite failures,
malfunctions or outages that may require satellite replacement within
ten days of their occurrence.
(3) Commercial availability. Mobile-satellite service must be
commercially available ( viz. , offering services for a fee) in
accordance with the coverage requirements that pertain to each band as
a prerequisite to an MSS licensee's offering ATC service.
(4) Integrated services. MSS ATC licensees shall offer an integrated
service of MSS and MSS ATC. Applicants for MSS ATC may establish an
integrated service offering by affirmatively demonstrating that:
(i) The MSS ATC operator will use a dual-mode handset that can
communicate with both the MSS network and the MSS ATC component to
provide the proposed ATC service; or
(ii) Other evidence establishing that the MSS ATC operator will provide
an integrated service offering to the public.
(5) In-band operation. (i) In the 2 GHz MSS band, MSS ATC is limited to
an MSS licensee's selected assignment. MSS ATC operations on
frequencies beyond the MSS licensee's selected assignment are
prohibited.
(ii) In the Big LEO bands, MSS ATC is limited to no more than 7.775 MHz
of spectrum in the L-band and 11.5 MHz of spectrum in the S-band.
Licensees in these bands may implement ATC only on those channels on
which MSS is authorized, consistent with the Big LEO band-sharing
arrangement.
(iii) In the L-band, MSS ATC is limited to those frequency assignments
available for MSS use in accordance with the Mexico City Memorandum of
Understanding, its successor agreements or the result of other
organized efforts of international coordination.
(c) Equipment certification. (1) Each ATC MET utilized for operation
under this part and each transmitter marketed, as set forth in § 2.803
of this chapter, must be of a type that has been authorized by the
Commission under its certification procedure for use under this part.
(2) Any manufacturer of radio transmitting equipment to be used in
these services may request equipment authorization following the
procedures set forth in subpart J of part 2 of this chapter. Equipment
authorization for an individual transmitter may be requested by an
applicant for a station authorization by following the procedures set
forth in part 2 of this chapter.
(3) Licensees and manufacturers are subject to the radiofrequency
radiation exposure requirements specified in § § 1.1307(b), 2.1091 and
2.1093 of this chapter, as appropriate. MSS ATC base stations must
comply with the requirements specified in § 1.1307(b) of this chapter
for PCS base stations. MSS ATC mobile terminals must comply with the
requirements specified for mobile and portable PCS transmitting devices
in § 1.1307(b) of this chapter. MSS ATC mobile terminals must also
comply with the requirements in § § 2.1091 and 2.1093 of this chapter
for Satellite Communications Services devices. Applications for
equipment authorization of mobile or portable devices operating under
this section must contain a statement confirming compliance with these
requirements for both fundamental emissions and unwanted emissions.
Technical information showing the basis for this statement must be
submitted to the Commission upon request.
(d) Applicants for an ancillary terrestrial component authority shall
demonstrate that the applicant does or will comply with the provisions
of § § 1.924 and 25.203(e) through 25.203(g) and with § § 25.252,
25.253, or 25.254, as appropriate, through certification or explanatory
technical exhibit.
(e) Except as provided for in paragraph (f) of this section, no
application for an ancillary terrestrial component shall be granted
until the applicant has demonstrated actual compliance with the
provisions of paragraph (b) of this section. Upon receipt of ATC
authority, all ATC licensees must ensure continued compliance with this
section and § § 25.252, 25.253, or 25.254, as appropriate.
(f) Special provision for operational MSS systems. Applicants for MSS
ATC authority with operational MSS systems that are in actual
compliance with the requirements prescribed in paragraphs (b)(1),
(b)(2), and (b)(3) of this section at the time of application may elect
to satisfy the requirements of paragraphs (b)(4) and (b)(5) of this
section prospectively by providing a substantial showing in its
certification regarding how the applicant will comply with the
requirements of paragraphs (b)(4) and (b)(5) of this section.
Notwithstanding § 25.117(f) and paragraph (e) of this section, the
Commission may grant an application for ATC authority based on such a
prospective substantial showing if the Commission finds that operations
consistent with the substantial showing will result in actual
compliance with the requirements prescribed in paragraphs (b)(4) and
(b)(5) of this section. An MSS ATC applicant that receives a grant of
ATC authority pursuant to this paragraph (f) shall notify the
Commission within 30 days once it begins providing ATC service. This
notification must take the form of a letter formally filed with the
Commission in the appropriate MSS license docket and shall contain a
certification that the MSS ATC service is consistent with its ATC
authority.
(g) Spectrum leasing. Leasing of spectrum rights by MSS licensees or
system operators to spectrum lessees for ATC use is subject to the
rules for spectrum manager leasing arrangements ( see § 1.9020) as set
forth in part 1, subpart X of the rules ( see § 1.9001 et seq. ). In
addition, at the time of the filing of the requisite notification of a
spectrum manager leasing arrangement using Form 608 ( see § § 1.9020(e)
and 1.913(a)(5)), both parties to the proposed arrangement must have a
complete and accurate Form 602 ( see § 1.913(a)(2)) on file with the
Commission.
