At Mobile World Congress Americas, Sprint and Ericsson unveiled results of the first U.S. 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, reports Business Wire on September 12, 2017. 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.
"Massive MIMO is a game changer for adding capacity to our network and taking LTE Plus to the next level," said Dr. John Saw, Sprint CTO. "This technology is a tremendous competitive advantage for Sprint, enabling us to maximize our deep 2.5 GHz spectrum holdings. Massive MIMO will be key to meeting our customers’ growing demand for unlimited data, as well as offering Gigabit LTE and 5G services."
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.
