Sprint and Ericsson with 2,5 GHz MIMO test

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.

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.
