Ericsson and Telefonica demonstrate live, over-the-air LTE-U based on RBS 6402 indoor pico cell
Announced Date: 3/30/2016 Published Date: 3/31/2016

Ericsson and Telefónica announced they have demonstrated live, over-the-air delivery of LTE-U on Telefónica's network based on the RBS 6402 indoor pico cell solution with support for three standards (LTE, WCDMA and WiFi), ten frequency bands and delivering up to 300 Mbit/s LTE carrier aggregation.

The LTE-U functionality is a commercially available Ericsson Networks Software capability that enables operators to utilise unlicensed 5 GHz spectrum in combination with licensed LTE spectrum. This allows operators to increase downstream data speeds in indoor environments, enhance application coverage and increase the quality of subscribers' mobile data experience.

Ericsson also announced the implementation of a range of enhancements to its Networks Software LTE-U offering, including: improved LTE-U performance and efficiency; reduced LTE-U transmission duration in line with 3GPP Release-13 License Assisted Access (LAA) specifications; support for the migration to 3GPP Release-13 LAA via software upgrades for the RBS 6402 providing listen before talk (LBT) for LTE-U and co-existence between LTE-U and Release-13 LAA devices on the same LAA carrier.

The enhancements will allow operators worldwide to leverage unlicensed 5 GHz spectrum to deliver improved peak data rates and capacity prior to 3GPP Release-13 LAA becoming available where national regulations allow the use of pre-Release-13 LAA standards.

Last year, Ericsson announced that its LAA/LTE-U solution, specifically designed to improve indoor app coverage for smartphone users, was live in Ericsson labs and supporting the aggregation of licensed and unlicensed spectrum to deliver peak rates up to 450 Mbit/s, as well as enabling fair sharing of spectrum between mobile and WiFi devices.

Ericsson noted the lab trial had been achieved in cooperation with Qualcomm Technologies and that mobile operators including Verizon, SK Telecom and T-Mobile USA were exploring the performance benefits offered by LAA/LTE-U.

Subsequently, in September Ericsson and Qualcomm Technologies announced a collaboration to demonstrate LTE-U over the air with the aim of achieving peak throughput of up to 300 Mbit/s. The trial involved Ericsson's second-generation indoor picocell base station, the RBS 6402, with multi-standard, multi-band capabilities and a Qualcomm Snapdragon 820 processor with X12 LTE.
