Industry-first leverages Licensed Assisted Access (LAA) and five-component carrier aggregation on 14 antenna layers
Commercial Nokia AirScale Micro Remote Radio Head (RRH) solution used to aggregate licensed and unlicensed LTE carriers and deliver gigabit speeds with 4×4 MIMO and 256 QAM
Lays ground for enhanced network performance in busy, urban locations on path toward 5G
Espoo, Finland and Bellevue, Washington — February 22, 2018 — Nokia and T-Mobile achieved download speeds of 1.3 Gbps using commercial Nokia technology with Licensed Assisted Access (LAA). This is an industry first using the Nokia commercial AirScale platform to support 14-layer transmissions. This achievement shows how wireless companies like T-Mobile can leverage available licensed and unlicensed spectrum assets to boost performance for customers in high-traffic urban locations, using Nokia’s technology for the deployment of high capacity small cells as they evolve network infrastructure toward 5G.
"We are working to deploy small cells that support LAA and build on the LTE-Advanced features we've deployed across the country, laying a foundation for 5G," said Neville Ray, Chief Technology Officer at T-Mobile. "Our priority is ensuring customers have the best mobile experience, so we are accelerating LAA and five carrier aggregation to give them even higher speeds and greater network performance."
"Nokia is providing a path towards 5G that allows operators like T-Mobile to attain gigabit speeds with LTE by leveraging all available licensed and unlicensed spectrum," said Marc Rouanne, president of Mobile Networks at Nokia. "With LAA, are helping T-Mobile gain higher download peak rates than could be achieved with licensed spectrum alone. This adds capacity beyond the spectrum licensed to this operator, and the existing network sites are used with limited TCO investment."
The tests, conducted at T-Mobile's lab in Bellevue, Washington, used commercial Nokia AirScale Micro RRH connected to an AirScale system module. Speeds of 1.3 Gbps were achieved by aggregating LTE carriers in licensed and unlicensed bands using five-component carrier aggregation, 256QAM, 4×4 MIMO and LAA on 14 antenna layers.
