Ericsson and Singtel Achieve 1.1 Gbps in LLA Trial

Singtel, Ericsson Reach Gigabit Speeds in LAA Trial

Singtel and Ericsson (NASDAQ: ERIC) have achieved an Asia-Pacific first in wireless technology by delivering a peak speed of 1.1 Gbps in a joint trial of a new configuration of Licensed Assisted Access (LAA) technology.

Conducted in a Singtel laboratory, the trial delivered speeds that breached the 1 Gbps barrier by combining several key LTE technologies including 256 QAM, 4x4 MIMO, and aggregating two licensed and three unlicensed spectrum bands on a TM500 Test System device [1] .  

Mark Chong, Singtel’s Group Chief Technology Officer says: “We are very encouraged by this breakthrough in peak speeds. In Singapore, a large percentage of mobile traffic is generated indoors with more mobile customers browsing the web, streaming video and accessing cloud applications on the go . We are now in a position to deploy LAA technology to boost our LTE mobile capacity to meet increasing traffic demand. This will allow us to deliver a faster and more reliable mobile connectivity experience even during peak periods.”  

The unique 12-layered LAA configuration used in the trial will provide 2 to 3 times faster than prevailing peak LTE speeds, resulting in enhanced user experience, especially in high traffic indoor environments such as shopping malls.  Following this successful trial, Singtel will explore the feasibility to deploy the technology on Singtel’s network.  

Martin Wiktorin, Head for Ericsson Singapore, Brunei & the Philippines, says: “Licensed Assisted Access took wireless technology to a whole new level, delivering the increased capacity and faster speeds that operators demand as they evolve their networks. This trial is a significant milestone in the use of LAA, pushing the limits of Gigabit LTE in a unique configuration of advanced technologies.”

[1] In the trial, four layers with 4X4 MIMO on licensed spectrum were used, as well as 2 layers on a second licensed band, and six layers with LAA (2 layers X 3 unlicensed bands). The Ericsson Radio System hardware used included Radio 2203 for the licensed spectrum and Radio 2205 for the LAA (unlicensed spectrum). All radios were connected to a single Baseband 5216.
