SmarTone and Ericsson carry out trial of LAA on live network

29 Aug 2017

Hong Kong’s SmarTone and Swedish vendor Ericsson claim to have taken ‘a significant step toward 5G’, announcing the successful trial of Licensed Assisted Access (LAA) technology in a live over-the-air demonstration in Hong Kong. With LAA allowing for the use of unlicensed spectrum in the 5GHz band in combination with licensed spectrum, in the trial SmarTone was said to have used one LTE 10MHz band aggregated with three 20MHz bands of unlicensed spectrum. Together with 4CC carrier aggregation, 4×4 multiple-input, multiple-output (4×4 MIMO) and 256QAM technologies, the trial utilised used a Qualcomm Snapdragon X16 LTE mobile test device and Ericsson’s micro Radio 2205 for LAA.

Commenting on the development, SmarTone’s CTO Stephen Chau said: ‘SmarTone is very pleased to have completed the first LAA trial in Hong Kong. LAA is an important technological evolution that can combine licensed and unlicensed spectrum to provide LTE service.’
