To Whom It May Concern:

                Consistent with the standards set forth in Section 5.61 of the Federal
        Communications Commission’s (Commission’s) Rules, 47 C.F.R. § 5.61, Red Rover Ltd, on
        behalf of Yuma School District, requests Special Temporary Authority (STA) to conduct
        demonstrations of Shared Spectrum experimental 4G LTE Cell Base Stations in Yuma,
        Arizona. Operations under this STA would be consistent with the Part 96 rules the
        Commission has adopted to govern use of the 3.5 GHz band. The STA is sought for a
        period of 180 days beginning on 02/01/2017. Red Rover Ltd outlines below its need for
        the requested STA and the reasons that the STA should be granted expeditiously.

                 The STA is needed to execute operation and performance of 4G LTE Cell in the
        3.5 GHz band, which the Commission has designated for broader use. The operation of
        Cell Base Stations will be consistent with the Commission’s Part 96 rules and the
        incumbent operators will be protected from any harmful interference. The School
        District of Yuma wants to test the capabilities of CBRS in providing Educational
        broadband Internet services to low income students at home. In support of their
        chromebook deployments and digital educational material online. This service will
        enhance the students and families for

                Red Rover and Yuma School District requests authorization to operate on the
        frequencies between 3680-3700 MHz, part of 3550-3700 MHz which have been opened
        for innovative small cell spectrum sharing in connection with the new Citizens
        Broadband Radio Service (CBRS). Operations across the proposed frequencies will be
        consistent with the rules for Category B CBRS devices (CBSDs) set forth in Part 96 of the
        Commission’s rules. As stated above and described below, Red Rover Ltd and Yuma
        School District will avoid harmful interference to incumbent operations throughout the
        band, and to operations in adjacent bands.

                 Planned Operations

               Red Rover anticipates performing the following tests under the requested STA.
        The proposed experimental operations in the 3.5 GHz band will be conducted without
        harmful interference to other authorized users.

            •    4G LTE outdoor coverage and performance: Red Rover Ltd in collaboration with
                 its Air Span radio equipment, model Air Symphony 4200 will test:
                      o The operation of the Cell base station to understand the coverage and
                          performance of indoor base stations in the 3.5 GHz band in rural
                          environments.
                              § The frequency of operation will be limited to 3650 to 3670 MHz
                              § A single antenna site will be established on existing muli-story
                                  structures.
                              § The network will broadcast, “filter content” to students at
                                  home. The desire outcome is the ability to provide educational
                                  Internet services to low income students at home.
                              § While traditional the FCC Educational Broadband Spectrum
                                  (EBS) is used for these deployments, Yuma School District does
                                  not have, nor can receive new EBS allocation. The application of
                                  CBRS would open the door for other Educational Institutions to
                                  consider this new spectrum in support of their students needs.
                      o The performance and operation of a CBSD when instructed by SAS to
                          switch frequency.
                      o The impact on an end user when a CBSD has switched its frequency
            •    SAS Management of Shared Spectrum: Red Rover, in collaboration with its SAS
                 Administrator (Federated Wireless) and radio partner Air Span, will test
                 spectrum sharing, including General Authorized Access (GAA) registration, CBSD
                 spectrum grant request and SAS response, spectrum grant revocation, and
                 simulated protection scenarios in an operation environment.

                 Non-Interference Analysis

               Operation under the STA will not adversely impact any authorized user of RF
        Spectrum.

               Morphology of Test Site: The city of Yuma is located between a series of
        mountain ranges. The location is urban and geography is mix with several tall buildings
        thoughout the town.

                The test site located at the Yuma High School campus. The site has existing
        Multi-story buildings that will be used as the radio towers. These existing structures
        assure no aircraft flight pattern issues.

                     o   A single eNodeB (antenna site) will be tested providing 360 degree
                         broadcast of the 4G LTE signal using the TDD protocol. The network will
                         provide broadband wireless Internet service to a test bed of students.

                   o   With the higher frequency and low transmit power, reduces the conflict
                       to adjoining areas.

               CBSD power will be limited to 47dBm/10MHz (EIRP) in alignment with CBSD’s
        Category B specifications

                Radar Protection (Shoreline): Yuma is not located within the protected zone,
        regardless, we select the use of the 3680-3700MHz frequency to avoid any possible
        contention with ship born radar. Red Rover Ltd does not expect any interference to
        Radars that operate on the shorelines.

                Federal Government Radiolocation Facilities: The Yuma test bed is not within
        the protected zone. Yet, to avoid any conflicts, we request 3680-3700MHz frequency to
        avoid any possible contention with military facilities meeting the 80 km distance
        requirement of the Part 96 rules.

                Ground Based Radar: The City test bed is located outside of any ground-based
        radar Exclusion Zone. The STA desired frequency is 3680-3700MHz frequencies to avoid
        any possible contention with ground-based radar.

                International Border: is more than 1800 km from the nearest Canadian border
        and over 29 km from the Mexican border. The STA site is to the far north of Yuma city
        providing the highest protection from conflict with operations in Mexico. Based on the
        Antenna hight and RF power, there is free space to prevent and conflict.

                In-Band FSS Protection: The Commission has identified in-band fixed satellite
        service (FSS) operations in 3600-3700 MHz that require protection under Part 96. Part
        96 further requires coordination with any in-band FSS operations within a 150 km
        coordination contour, operating within the 3680-3700MHz MHz band. There are no in-
        band FSS operations within the protected zone.

                Adjacent Band FSS Protection: The Commission has identified adjacent band
        FSS operations in the 3700-4200 MHz that require protection under Part 96. Part 96
        requires adjacent band FSS protection within 40km of the FSS site. There are no
        adjacent band FSS operations within the protected zone.

               Part 96 requires a blocking level of -60 dBm. Assuming Free Space path loss
        between a CBSD in Yuma and the nearest FSS over 100 miles the blocking level of -60
        dBm will not be an issue due to free space distance between the sites.

              Part 90 (GWBL): A search in the FCC ULS for any GWBL license holders within
        18KM of the proposed STA site indicated there are are current GWBL within the area
