US Cellular, Ericsson achieve 9Gbps in 5G trial

19 Dec 2016

US Cellular and Ericsson have successfully completed joint testing of 5G technology in Madison, Wisconsin, achieving peak throughput speeds of 9Gbps. The Swedish vendor installed 5G radios on a tower currently in commercial service by US Cellular, and used a block of 15GHz spectrum through an experimental licence granted by the Federal Communications Commission (FCC). The trial was run under varying environmental conditions to simulate real world use, and the tests evaluated a number of new radio access carrier combinations to verify their benefits to network throughput and performance. The trials achieved peak throughput of 1.5Gbps at a distance of one mile and 9Gbps at a distance of 787 feet. Also tested were radio resource sharing, beamforming, beam tracking, peak throughput and multi-user MIMO technologies. Michael S. Irizarry, US Cellular’s executive vice president and chief technology officer, commented: ‘This latest trial with Ericsson demonstrates incredible 9Gbps speeds in an environment that was close to a real world scenario, and we look forward to collaborating with Ericsson on the development of standards for a healthy 5G ecosystem.’
