Applicant seeks Special Temporary Authority (STA) to operate a 28 GHz experimental 5G NR
system on a collaborative trial conducted on the campus of the University of Southern California
located on 3096 S. McClintock Avenue, Los Angeles California, during November 15, 2018 to
December 10, 2018 time period. The STA is needed from November 10, 2018 to December 20,
2018.

The industry organization 3rd Generation Partnership Project (“3GPP”) has completed the R15
NR specifications in June 2018 which together with 3GPP final NR specifications in Release 16
will be submitted for consideration as an IMT 2020 Radio Interface Technology at the July 2019
ITU-R WP5D meeting. 5G systems will utilize advanced antenna technologies with
beamforming and multiple in multiple out (“MIMO”) technology, as well as more efficient
coding and modulation schemes. These technologies are expected to result in higher spectral
efficiencies and reduced latency, enabling gigabit per-second (Gbps) mobile and fixed broadband
services, significantly faster than today’s average 4G speeds using the Long Term Evolution
(“LTE”) connections.

Applicant’s 5G trial will involve communications between up to 2 fixed (FX) base stations
(gNodeBs), and up to 4 user equipment (UE) units placed within 500 meters of the base station
antennas. The base stations and the UE antennas will be all placed indoors at a height of less
than 6 meters above the floor inside Building 4 of the Village at USC. The base stations will
have connectivity to internal servers and/or the Internet, to provide content over the 5G air
interface. The UEs can provide services to various devices through Wi-Fi access points that are
connected to the UEs via Ethernet cable.

The 5G air links provided though this STA will be used to test and verify the performance of
various applications that require very high speeds and very low latencies, to confirm the benefits
of 5G NR for such applications. The results will provide valuable information to users whose
feedback could be used to enable product development and system optimization, as well as to
improve future system standards and the deployment processes.
