T-Mobile US and Ericsson have achieved speeds of 1.1Gbps using twelve-layer Licensed Assisted Access (LAA) technology. The two parties claim that the tests are the first in the world to hit speeds beyond the 1Gbps threshold using unlicensed spectrum. The demonstration took place at T-Mobile’s Bellevue, Washington lab using the Ericsson Radio System and test equipment from Cobham Wireless. The data speeds were achieved by combining several key LTE technologies, including: 256 QAM, 4×4 MIMO and LAA. In terms of spectrum, the tests aggregated two licensed carrier channels and three unlicensed carrier channels.
