Singtel, Ericsson demo LTE LAA on live 4G network

Singtel and Ericsson have announced they have successfully conducted a live trial of pre-standard License Assisted Access (LAA) on Singtel’s network earlier this month. The trial was completed after a 2-week period of testing using multiple RBS 6402 indoor small cells, Wi-Fi access points, prototype LAA devices, and Wi-Fi devices.

Singtel provided the licensed spectrum of 1800 MHz (20 MHz) for the LTE anchor carrier, augmented with 5 GHz unlicensed spectrum (20 MHz) in its live network deployed in an office building at Serangoon North. Extensive tests cases were conducted to demonstrate extended coverage and increased network capacity as well as seamless mobility with opportunistic aggregation of unlicensed spectrum, Singtel said.

A stationary live test at the office building demonstrated LTE License Assisted Access (LAA) throughput of 275 Mbps measured. The second test case showcased LAA ability to co-exist with Wi-Fi signals without affecting user experience in Wi-Fi. The trial showed that Wi-Fi users are better off with LAA as a neighbour and maintained consistent downlink throughput with and without LAA introduction.

Coverage testing was performed to demonstrate LAA ability to have better link performance, medium access control, mobility management, and improved coverage as compared to Wi-Fi Access point, and also to consistently provide higher user throughput speeds through handover between multiple small cells and across various radio conditions, Singtel also said.

Following the LAA trial, this service will be progressively deployed in Singapore over the next two years, beginning in the first half of 2017, enabling Singtel to extend its current in-building coverage capacity and provide an upgraded 4G service to its mobile customers. New handset models supporting LAA are expected to be available by early 2017. In the future, Singtel customers with LAA-capable handsets will be able to access peak download throughput up to 450 Mbps.
