Please explain in the area below why an STA is necessary:
The demonstrations using this STA 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.

Purpose of Operation
Please explain the purpose of operation:  Demonstration of the functionality and capabilities of fifth generation wireless communication systems. The applicant's 5G systems demonstrations will involve communications between fixed base stations placed inside a building at 601 New Jersey Ave., NW Washington DC 20001. The building has concrete walls and windows with coated glass as shown below. The 5G systems wireless link will be established between the base station and mobile user equipment ("UE") located in the same room or area as the base station, at a distance of within approximately 12 meters of the base station. The base station and UE will be operated within approximately 3 meters above floor level in the building. The base station will connect to an Internet service provider, which will provide Internet access for the purposes of 5G systems 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.
