2 Experiment Description
This experimental license purpose is to extend authorized testing granted under STA file 0460-
EX-ST-2016 granted May 3, 2016. There are no changes to the technical parameters or test
goals defined below in the original STA filing.

Qualcomm is working with partner companies to develop equipment that will use multiple
technologies, including 802.11 and LTE, in unlicensed 5 GHz frequency bands. This request for
Special Temporary Authority (“STA”) seeks authority to conduct very small scale product
development testing of this equipment at four trial sites.

The purpose of the proposed testing is to evaluate the technical performance of pre-commercial
LTE-U equipment, operating in downlink-only mode in the UNII-1 and UNII-3 portions of the 5
GHz band, in a highly controlled field environment in order to assist in the ultimate development
of commercial products. The testing will benefit the public interest by enabling the pre-
commercial testing of new products outside of a lab environment but in a controlled and managed
manner.

Since LTE-U was conceived, Qualcomm, T-Mobile and their partner companies have engaged in
extensive technical collaboration with, and outreach to, the Wi-Fi community. Indeed, Qualcomm
is part of that community. These efforts are ongoing, and Qualcomm will continue to work with
the Wi-Fi community to ensure successful coexistence in the UNII-1 and UNII-3 portions of the 5
GHz band.

In addition to the product development testing described above, Qualcomm, T-Mobile, and their
partner companies intend to conduct separate and independent LTE-U/Wi-Fi coexistence testing
in a real-world environment at a T-Mobile facility using a coexistence test plan being developed
by the Wi-Fi Alliance. This test plan is a product of extensive technical collaboration between the
Wi-Fi Alliance, T-Mobile, Qualcomm, and their partner companies and would be modified as
appropriate based on the specific environment to be used for the testing. The Wi-Fi Alliance
would be invited to observe these tests. This Wi-Fi Alliance test plan will initially be used for joint
coexistence testing to take place within a Wi-Fi Alliance certified lab.

This trial will consist of up to 10 small cells and access points that will use the transmission
parameters and operate inside the geographic regions defined in Section 4 below. Some
equipment also includes a 3GPP LTE base station that operates on 3GPP Band 4, also known as

                                                                                                          FCC Form 442
                 the US AWS band operated under 47 CFR Part 27. Transmission on AWS spectrum will occur
                 only with authorization from the respective spectrum licensee.

                 Mobile units will also operate within the RF coverage area of the small cell devices. The mobile
                 units are receive-only in the 5 GHz spectrum but also include an LTE transmitter that operates on
                 3GPP Band 4.

                 Up to 20 mobile stations will be used at each location for a total possible number of 80 LTE-U
                 capable mobile devices.

                 Although the devices are prototypes that have not completed formal equipment authorization, the
                 equipment used in this testing is compliant with 47 CFR Part 15 Subpart E and Part 27 Subpart E
                 technical requirements. Equipment from multiple equipment manufacturers will be used in the
                 evaluation testing. Qualcomm has the ability to shut down all transmissions operated under this
                 STA in the unlikely event any interference occurs.

                 The intent is to operate the evaluation devices, both small cells and mobile units, 24 hours per
                 day 7 days per week during the test period.

                 3 Interference Coordination
                 Immediate requests to stop transmissions under this STA should be emailed
                 to 5GHz.trial.shutdown@qti.qualcomm.com. Alternatively, a shutdown request can be

                 communicated to John Forrester at 858-845-7428 or jforrest@qti.qualcomm.com.
                                                                        20T




                 4 Evaluation Equipment Transmitter Information
                 802.11 access points and small cells supporting either LTE or 802.11 will be operating with the
                 transmitter parameters defined in Table 1. Both directional and omnidirectional antennas will be
                 used with the small cell systems within the maximum EIRP and antenna gain constraints defined
                 in Table 1. The LTE small cell will simultaneously transmit a single 20 MHz signal in a 5 GHz
                 band and an LTE in the AWS band.

                 Mobile devices will operate near the small cell sites with the transmitter parameters defined in
                 Table 1. LTE mobile devices support AWS FDD operation with an LTE uplink in the AWS band
                 but are receive only for LTE in the 5 GHz band. Mobile devices also support 802.11 modes in the
                 requested 5 GHz band.

                 Table 2 defines the deployment areas where small cell and access points will be located during
                 the evaluation testing. Up to 6 fixed stations will be installed indoors within each region defined in
                 Table 2.
