T-Mobile US has begun to deploy 4x2 MIMO antenna technology in its LTE network to enhance network performance at the cell edge and enhance the customer experience, reports Telecompaper.com, citing GigOM, a blog-related media to which T-Mobile confirmed that it is deploying the new antenna technology, but did not say where it is launching the new technology first. GigaOM, however, has spotted such deployments so far in Chicago, Dallas and San Antonio, Texas.

By moving to 4x2 MIMO, T-Mobile is doubling the number of antennas, and thus, data transmission paths, used in standard LTE deployments, which use 2x2 MIMO. MIMO sends data over two parallel transmission paths from cell towers to devices at the end of the network. "We do see the benefits 4x2 MIMO offers and will be deploying this in many cities in 2014 as part of our Wideband LTE rollout," Mark McDiarmid, T-Mobile\'s vice president of radio network engineering, said in a statement to GigaOM.

"All of T-Mobile\'s available devices currently support 4x2 MIMO and we\'ll ensure that new devices will as well. We believe this will be one of the first deployments by a top carrier network in the US."
