Applicant seeks a two (2) year experimental license to demonstrate to the functionality and
capabilities of the fifth generation (“5G”) wireless communication systems using experimental
equipment operating in the 28 GHz and 39 GHz spectrum bands.
The industry standards organization, 3rd Generation Partnership Project (“3GPP”), is developing
5G standards, which are expected for release beginning in 2018. 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, reduce latency to 1-5 milliseconds, and enable
gigabyte per-second (Gbps) mobile and fixed broadband services, significantly faster than
today’s average 4G speeds using long term evolution (“LTE) connections.

Applicant’s 5G demonstrations will involve communications between fixed (FX) base stations
placed indoors in a room or open space located inside a building at 208 S. Akard Street, Dallas
TX, 75202. The building has concrete walls and windows with coated glass as shown below.
The 5G wireless link will be established between the base station and mobile user equipment
(“UE”) located in the same room or area, at a distance of about 10 meters apart. The base station
and UE will be operated at 3 meters and 2 meters, respectively, above floor level. The base
station will have connectivity to an ISP providing Gbps Internet access for the purposes of 5G
demonstrations using various applications and web servers. The UEs can provide services to
various devices through Wi-Fi access points connected to the UE through Ethernet cable.

The demonstrations using this license will provide valuable information to potential users whose
feedback on the perceived performance of services provided through these 5G systems will also
enable future standards and system optimizations.
