Sprint, Ericsson Conduct Field Tests for 2.5 GHz Massive MIMO

At Mobile World Congress Americas, Sprint (NYSE: S) and Ericsson (NASDAQ: ERIC) has unveiled results of the first US 2.5 GHz Massive MIMO (multiple input, multiple output) field tests conducted in Seattle, Washington and Plano, Texas using Sprint´s spectrum and Ericsson´s 64T64R (64 transmit, 64 receive) radios, the company said.

The two companies are preparing for commercial deployment next year, with Massive MIMO radios capable of increasing Sprint´s network capacity up to ten times.

Testing of Massive MIMO on the Sprint LTE Plus network in downtown Seattle showed a capacity increase of approximately four times compared to an 8T8R antenna. To showcase this capacity, Sprint convened 100 people with Samsung Galaxy S7 phones and ran simultaneous file downloads on a timed-test on all networks. The testing showed a 100 percent success rate on the Massive MIMO-powered Sprint network, which was a significantly higher result compared to the other networks.

In Plano, Texas, Sprint and Ericsson also recently tested Ericsson´s 64T64R Massive MIMO radios reaching peak speeds of more than 300 Mbps using a single 20 MHz channel of 2.5 GHz spectrum.

For both field trials, Ericsson provided the radio network infrastructure and backhaul equipment. Sprint and Ericsson together developed the test cases and requirements, which included a variety of performance scenarios involving multi-user and non-stationary testing. The Radio Network infrastructure included Ericsson´s next-generation 5G-ready AIR6468 radio, and the backhaul equipment utilized the MINI-LINK 6352 R2 microwave radios which can provide up to 10 Gbps of backhaul, future proofing the network for 5G.

Sprint is a communications services company that creates more and better ways to connect its customers to the things they care about most.

Ericsson is a world provider of communications technology and services with headquarters in Stockholm, Sweden. Read more on www.ericsson.com.
