                                  Request for Special Temporary Authority

          O3b Limited (“O3b”), pursuant to Section 25.120 of the Commission’s rules, 1 hereby respectfully
requests special temporary authority (“STA”) to operate an earth station to be located at Haleiwa,
Hawaii (“Hawaii 2.4m Earth Station”) that will communicate with the satellite system operated by O3b.
In this filing, O3b seeks a 60-day STA for the period between December 15, 2014 and February 13, 2015.
O3b proposes to operate the Hawaii 2.4m Earth Station during this term in accordance with the
parameters specified in Schedule B of the license application for the Hawaii 2.4m Earth Station that O3b
is filing concurrently with this STA request (“2.4m Hawaii Earth Station License Application”). 2

        The Hawaii 2.4m Earth Station will be used to support the telemetry, tracking and command
(“TT&C”) that are handled by the O3b gateway earth station in Haleiwa, HI (“Hawaii Gateway Earth
Station”). As discussed below, grant of the requested authority is in the public interest as it will allow
O3b to make its network more resilient.

Test Details and Public Interest Showing

        The Hawaii 2.4m Earth Station will communicate with O3b’s UK-authorized, Ka-band, Medium
Earth Orbit, non-geostationary satellite orbit (“NGSO”) Fixed-Satellite Service (“FSS”) system. 3

        The frequencies to be used by the Hawaii 2.4m Earth Station are:

             •   27.6-28.4 GHz, 28.6-29.1 GHz (uplink)
             •   17.8-18.6 GHz, 18.8-19.3 GHz (downlink)

        The Hawaii 2.4m Earth Station antennas will be mounted on a fixed platform. Although the
pointing angle of the antennas will change as O3b’s in-orbit satellites are tracked, the platform will
remain stationary during operation.

          The Hawaii 2.4m Earth Station will consist of two (2) 2.4m General Dynamics Satcom antennas.
O3b has previously been granted an STA to operate the same 2.4m earth station model at the O3b
facility in Bristow, Virginia 4 and has filed an application for a license to operate this earth station model
at the same location. 5

        Grant of this application will serve the public interest, convenience and necessity by allowing
O3b to enhance its system’s resiliency. The Hawaii 2.4m Earth Station will communicate with O3b’s
system and provide support and redundancy for the telemetry, tracking and command (“TT&C”) and
data feed functions that are handled by O3b’s previously-licensed gateway, which is located at the same

facility as the Hawaii 2.4m Earth Station. 6 The Hawaii 2.4m Earth Station will also permit O3b to conduct
customer demonstrations should the need arise. The Hawaii 2.4m Earth Station will make the O3b
system more resilient and ensure that its customers around the globe continue to receive high quality
service from O3b.

The O3b Satellite System

        In its initial FCC application, which sought authority for the Hawaii Gateway Earth Station, O3b
stated that it planned to operate eight NGSO satellites that would be spaced equally, i.e., at 45°
intervals. 7 The Commission granted this application. 8

         O3b has filed an application seeking to modify its Hawaii Gateway Earth Station license to give it
the flexibility to operate up to two of its eight NGSO satellites as in-orbit spares. 9 The remaining
satellites would be equally spaced in O3b’s authorized orbital plane, and each in-orbit spare would be
co-located with a non-spare satellite. 10 O3b has been granted an STA pending action on its modification
application. 11

               •    Comsearch Reports. Comsearch Reports are provided for bands in which terrestrial
                    frequencies have primary allocations. Comsearch notified operators within a
                    coordination zone calculated using the ITU RR Appendix 7 guidelines.
                        o 27.6-28.35 GHz band. As stated in the attached Frequency Coordination Report,
                            Comsearch has notified all existing and proposed LMDS licensees that are within
                            the coordination contours of the Hawaii 2.4m Earth Station and that potentially
                            could be affected by O3b’s transmissions in the 27.6-28.35 GHz portion of the
                            Ka-band. No objections were received from any of these parties.
                        o 18.3-18.6 GHz band. As stated in the attached Interference Analysis Report, for
                            operations in the 18.3-18.6 GHz band, the Hawaii 2.4m Earth Station will
                            operate satisfactorily within the 18 GHz microwave environment, and there will
                            be no restrictions of its operation due to interference considerations.
               •    Comsearch and O3b Field Strength Analysis. O3b is aware that there is a FCC monitoring
                    station at Waipahu, Hawaii. To demonstrate compliance with Section 25.203(g)(1) of the
                    Commission’s rules, O3b is providing the attached Field Strength Analysis conducted by
                    Comsearch and a more recent analysis conducted by O3b to demonstrate that the
                    monitoring station at Waipahu will be adequately protected.

           Further, O3b incorporates by reference the following technical parameters previously provided
by O3b:

               •    Schedule S. In its application for the Hawaii Gateway Earth Station, O3b submitted a
                    Schedule S describing its satellite system’s technical characteristics. 12 The Schedule S
                    correctly described the O3b satellite system for that application, and numerically
                    enveloped all of the necessary parameters for future earth station applications. In order
                    to assist the Commission in processing present and future applications, O3b
                    subsequently provided a modified Schedule S that incorporates additional information
                    submitted to the Commission since the Hawaii Gateway Earth Station application was
                    filed. 13 O3b will operate its Hawaii 2.4m Earth Station within the parameters described
                    in O3b’s modified Schedule S.
               •    U.S. Government Coordination. O3b has completed all necessary coordination with
                    U.S. government satellite networks operating in Ka-band, including GSO and NGSO
                    networks, as well as their associated specific earth stations filed under 9.7A and 9.7B of
                    the ITU Radio Regulations through other administrations. O3b has also completed
                    coordination, according to US footnote 334 of the FCC table of frequency allocations,
                    with the U.S. government, and this US334 coordination agreement specifically provides
                    for additional earth stations in U.S. territory operating with O3b’s satellites, such as the
                    Hawaii 2.4m Earth Station. As a result, O3b’s existing US334 coordination agreement
                    covers the use of the Hawaii 2.4m Earth Station as requested in this application.

            •    Antenna Patterns. O3b previously submitted measured 30 GHz band antenna

                 the pending Bristow License Application.14



Proposed Spectrum Use

      O3b’s proposed Hawaii 2.4m Earth Station operations in shared bands are consistent with the
Commission’s rules and policies. O3b addresses each of these bands below.

UPLINK

27.6-28.35 GHz – Secondary uplink band shared with primary LMDS.

        The 27.6-28.35 GHz uplink band is allocated to the local multipoint distribution service (“LMDS”)
on a primary basis. FSS operations are allocated on a secondary basis in the same band. Accordingly,
O3b’s proposed operations in this band must not cause harmful interference to primary LMDS stations.

        The Comsearch coordination report submitted with O3b’s 2.4m Hawaii Earth Station License
Application demonstrates that O3b can operate its Hawaii 2.4m Earth Station on a secondary basis in
this band without causing harmful interference to LMDS licensees. Comsearch sent a coordination
notice to all existing and proposed terrestrial licensees within the Comsearch coordination contours of
the Hawaii 2.4m Earth Station site. No objections were received from any of the incumbent licensees.

28.35-28.4 GHz – Secondary uplink band shared with primary GSO FSS stations.

         In the 28.35-28.4 GHz band, there is a primary allocation for GSO FSS systems and a secondary
allocation for NGSO FSS systems. O3b’s Hawaii 2.4m Earth Station transmissions in this band will be
consistent with their secondary status vis-à-vis GSO FSS transmissions. The Commission has allowed
similar secondary use of frequencies in the Ka-band uplink allocated to GSO FSS on a primary basis
where applicants are prepared to accept interference from primary operations and can demonstrate
that their proposed operations are not likely to cause harmful interference to primary operations. 15 O3b
satisfies both of these standards.

         As a secondary user of the 28.35-28.4 GHz band in the United States, O3b makes no claim of
protection from interference from U.S.-licensed GSO FSS networks in this band segment. As for O3b’s
uplink operations in the 28.35-28.4 GHz band, the ITU has developed uplink equivalent power flux
density limits (“EPFDup”) limits to protect co-frequency GSO FSS operations from unacceptable
interference from NGSO FSS systems operating in the same frequencies. Specifically, in accordance with
Article 22 of the ITU Radio Regulations, if the applicable EPFDup limits are met, the NGSO FSS satellite
system is considered to have met its obligations to protect GSO FSS networks from unacceptable
interference. O3b demonstrated that its Hawaii Gateway Earth Station operating at the authorized

power levels will meet the applicable ITU EPFDup limits in all frequency ranges where these limits apply,
due to the inherent angular separation between the O3b and geostationary orbits when viewed from
the Earth at latitudes away from the equator. 16

         The Hawaii 2.4m Earth Station will be located at the same site as the Hawaii Gateway Earth
        17
Station, which results in the same angular separation between the O3b and geostationary orbits as
viewed from the Earth and an equal assurance that the applicable ITU EPFDup limits will be met by O3b’s
proposed operations. The proposed Hawaii 2.4m Earth Station operations, therefore, also will meet the
applicable ITU EPFDup limits. In any event, O3b confirms that its operations will be on a secondary basis
relative to U.S.-licensed GSO FSS networks in the same band.

28.6-29.1 GHz – Primary uplink band for licensed NGSO FSS Systems.

        Under the Commission’s Ka-band frequency plan, the frequencies 28.6-29.1 GHz may be used on
a primary basis by licensed NGSO FSS systems. 18 O3b recognizes, however, that operations under an
STA for the Hawaii 2.4m Earth Station operations will be on a secondary, non-harmful interference basis.
As shown below, the Hawaii 2.4m Earth Station operations will provide the requisite protection to
allocated services operating in this band.

         Avoidance of interference to GSO FSS systems. The proposed operations will not cause any
interference into, or require protection from, any co-frequency GSO satellites. As previously shown, 19
there is an inherent angular separation between the O3b and GSO arcs from the perspective of earth
stations located away from the equator. The Hawaii 2.4m Earth Station will be located at the same site
as the Hawaii Gateway Earth Station, 20 which results in the same angular separation between the O3b
and geostationary orbits as viewed from the Earth. This means that the angular separation between the
O3b and GSO arcs from the Hawaii 2.4m Earth Station will be equal to the 7 degree separation accepted
by the Commission when it approved O3b’s Hawaii Gateway Earth Station. This ensures that GSO FSS
systems will be adequately protected.

         Avoidance of interference to or from Fixed Service (i.e., terrestrial) stations. Interference from
the O3b Hawaii 2.4m Earth Station transmissions into U.S. terrestrial Fixed Service (“FS”) receivers in the
28 GHz band is a non-issue because there is no allocation in the Commission’s Ka-band Frequency Plan
for FS stations operating in the 28.6-29.1 GHz band in the United States. 21

DOWNLINK

17.8-18.3 GHz – Primary downlink band for licensed FS Systems.

        This frequency band is allocated on a primary basis to FS, and there is no secondary allocation
for NGSO FSS in the band. Accordingly, O3b requests a waiver of the Ka-Band Plan and Section 2.106 of
the Commission’s rules to permit O3b to operate its NGSO FSS system in the 17.8-18.3 GHz band for
downlink operations on a non-conforming, non-interference basis. As noted above, in analyzing requests
for non-conforming spectrum uses, the Commission has indicated it will generally grant such waivers
where there is not potential for interference into any service authorized under the Table of Frequency
Allocations and when the non-conforming operator accepts any interference from allocated services.

         In this case, O3b’s proposed non-conforming use of the 17.8-18.3 GHz frequency band for
downlink operations will not cause harmful interference to FS operations in the same band. This is
because O3b will meet the PFD limits at the earth’s surface prescribed by the ITU for the protection of
terrestrial services in this band. In addition, as a non-conforming user, O3b will accept interference from
FS operations in the band.

        In addition, an Interference Analysis Report from Comsearch submitted with O3b’s 2.4m Hawaii
Earth Station License Application indicates that there will be no restrictions of O3b’s operations due to
interference considerations.

         In light of the foregoing, a waiver of Section 2.106 of the Commission's rules and the Ka-Band
Plan is warranted because no harmful interference will result to incumbent FS operations, O3b can
operate satisfactorily within the 18 GHz microwave environment, and the public interest is otherwise
served by permitting O3b to support its commercial operations.

18.3-18.6 GHz – Non-conforming downlink band shared with primary GSO FSS stations.

          The 18.3-18.6 GHz band is allocated in the United States on a primary basis to GSO FSS. In the
18.3-18.6 GHz downlink band, the ITU has developed downlink equivalent power flux density
(“EPFDdown”) limits to protect GSO FSS networks from unacceptable interference from NGSO FSS systems
operating in the same frequencies. Specifically, in accordance with Article 22 of the ITU Radio
Regulations, if the applicable EPFDdown limits are met, the NGSO FSS satellite system is considered to
have met its obligations to protect GSO FSS networks from unacceptable interference. O3b confirms
that its system will meet the applicable ITU EPFDdown limits in all frequency ranges where these limits
apply. 22

       As an example of how these limits will be satisfied, O3b provided EPFDdown calculations for
transmissions to its Hawaii Gateway Earth Station. 23 O3b also showed how the EPFDdown limits can be

22 of the ITU Radio Regulations. See also Letter from Brian D. Weimer, to Marlene H. Dortch, in re O3b Application

satisfied at all latitudes. 24 O3b is able to satisfy the limits by taking advantage of the inherent angular
separation of the O3b and the GSO orbits when viewed from the surface of the Earth at latitudes away
from the equator. 25 Based on these prior showings, it can be seen that transmissions to O3b’s Hawaii
2.4m Earth Station will be within the EPFDdown limits.

18.8-19.3 GHz – Primary downlink band for licensed NGSO FSS Systems.

         Under the Commission’s Ka-band frequency plan, the frequencies 18.8-19.3 GHz may be used on
a primary basis by licensed NGSO FSS systems. 26 O3b recognizes, however, that operations under an
STA for the Hawaii 2.4m Earth Station operations will be on a secondary, non-harmful interference basis.
The Hawaii 2.4m Earth Station operations will provide the requisite protection to GSO FSS networks and
terrestrial stations operating in this band.

         Avoidance of interference to GSO FSS systems. This band is not allocated for GSO FSS networks. 27
Nevertheless, the proposed operations will not cause any interference into, or require protection from,
any co-frequency GSO satellites. As previously shown, 28 there is an inherent angular separation between
the O3b and GSO arcs from the perspective of earth stations located away from the equator. As
mentioned above, the Hawaii 2.4m Earth Station is located at the same site as the Hawaii Gateway Earth
Station, which results in the same angular separation between the O3b and geostationary orbits as
viewed from the Earth. This means that the angular separation between the O3b and GSO arcs from the
Hawaii 2.4m Earth Station will be equal to the 7 degree separation accepted by the Commission when it
approved O3b’s Hawaii Gateway Earth Station. This ensures that GSO FSS systems will be adequately
protected.

       However, because the operations O3b proposes in this STA request will be conducted on a
secondary basis, O3b agrees to accept any interference that its Hawaii 2.4m Earth Station may receive
from 18.8-19.3 GHz band GSO FSS networks

        Avoidance of interference to or from Fixed Service (i.e., terrestrial) stations. FS stations operating
in the 18.8-19.3 GHz band are no longer co-primary with FSS users in this band. 29 However, because the
operations O3b proposes in this STA request will be conducted on a secondary basis, O3b agrees to
accept any interference that its Hawaii 2.4m Earth Station may receive from 18.8-19.3 GHz band FS
