​Current Status And Progress Of AT&T And Verizon Mobile 5G Demonstration And Testing
Jun 07, 2018

According to the reports, US operators AT&T and Verizon are all ready to demonstrate or test mobile 5G initial applications through the 28GHz band and have applied for permission from the FCC.

AT&T plans to display "mobile" 5G connections over 100 meters to compatible user equipment, and then display how to send 28GHz signals through WiFi to the user equipment. At the same time, Verizon said it wants to use its fixed wireless network to provide 5G signals to mobile devices.

In essence, both operators want to test whether the 28GHz band is suitable for 5G mobile functions, although they use a fixed wireless network to accomplish this task. So far, fixed wireless trials have shown that the technology can provide gigabit or near-gigabit speeds at distances up to 2,000 feet, but there is little information about how the mobile service is implemented.

AT&T has obtained permission from the Federal Communications Commission (FCC) to "move" the 28GHz demo at the E3 game show in Los Angeles next month. The demonstration will use three base stations and three user equipments (UEs) within 100 meters of the base station antenna. 

AT&T said: "The base station will establish a connection with the internal server through the 5G NR for demonstration. The user equipment (UE) can provide services to various devices through the Wi-Fi access point connected to the UE via Ethernet cabling." AT&T called this demonstration a mobile demonstration "within 100 meters of base stations." AT&T has promised to launch mobile 5G services in 12 markets in the United States before the end of the year. Since there is no mobile 5G NR-compatible device yet, AT&T will distribute the indoor 5G signal to the Wi-Fi router through a wired connection.

At the same time, Verizon is demanding to expand tests conducted throughout the United States to test the operation of fixed base stations and mobile terminals in the 28GHz band.Verizon has said that it will provide fixed 1Gbps 5G service for the United States in 3 to 5 markets in the fourth quarter. Verizon has said that after the software update, it will be able to reuse most of the fixed infrastructure. If the FCC approves the update of experimental licenses, Verizon will step up testing such capabilities.
