US Cellular, the country’s fifth largest operator, said a 5G fixed wireless test conducted with Nokia proved some points about the technology.
The operator had teased news of the 28 GHz trial at last month’s CTIA show and has shared its first feedback.
Last month, US Cellular did not disclose the “incumbent vendor” with which it working, now it’s named the Finnish vendor.
The test, conducted in both indoor and outdoor environments, was possible through an experimental licence from US regulator FCC and involved streaming six simultaneous 4K ultra high definition videos.
For the outdoor testing, a team set up a point-to-point, clear line of sight scenario between a base station and user equipment. Just to give a real-world feel, the test involved impairments such as a dry wall, windows and metal panels, as well as moving the base station and user equipment behind trees and foliage.
In both environments, the tests managed to deliver speeds of 5 Gb/s and ultra-low latency under 2 milliseconds over the 5G link.
“As a result, the companies proved how a next-generation network can provide faster speeds and lower latency for US Cellular’s customers,” they said.
The two firms plan further testing. At CTIA, US Cellular said this would involve using 15GHz spectrum, in addition to the 28GHz band.
US Cellular’s focus on fixed wireless testing for 5G follows similar efforts from larger rivals AT&T and Verizon Wireless.
