Ericsson has demonstrated wireless data speeds of 1.1 Gbit/s using 12-layer Licensed Assisted Access (LAA) technology – the first in the world to hit speeds beyond the 1 Gbit/s threshold on unlicensed spectrum.
The data speeds were achieved by combining several key LTE technologies including 256 QAM, 4x4 MIMO, and LAA by aggregating two licensed carriers and three unlicensed carriers. LAA has been demonstrated previously on 10 layers, reaching download speeds of up to 1 Gbit/s. Extending this to 12 layers enables the higher speeds and flexibility using unlicensed carriers in the 5GHz band.
“T-Mobile has built the nation’s fastest LTE network by innovating and bringing new technologies to market for our customers. This LAA technology builds upon our deployments of 4x4 MIMO and 256 QAM and will give customers even greater access to near gigabit speeds in 2018,” said Neville Ray, Chief Technology Officer for partner T-Mobile. The demo also used the TM500 test systems from Cobham Wireless.
“Breaking the 1 Gbps-mark means that commercial gigabit speeds are not far from reality for many broadband users, with our LAA and MIMO technologies as key enablers. It is also an example of how innovatively we work with partners to push the boundaries of technology and achieve new milestones," said Fredrik Jejdling, Executive Vice President and Head of Networks at Ericsson.
The use of these LTE technologies on unlicensed spectrum complements licensed spectrum and makes it possible for a larger number of operators to reach gigabit speeds in their networks.
The Ericsson Radio 2205 allows operators to deploy LTE on the 5GHz unlicensed band in outdoor micro cell environments. Using LAA, the unlicensed carriers on these radios can be aggregated with licensed carriers on the micro cells or on nearby macro cells.
