SingTel, Ericsson and Qualcomm deliver 260Mbps download speeds in FDD/TDD carrier aggregation tests

8 Oct 2014

SingTel Mobile and equipment vendors Ericsson and Qualcomm have reportedly achieved peak download speeds of 260Mbps during a live demonstration of frequency division duplexing (FDD)/time division duplexing (TDD) carrier aggregation (CA) technology. The test used Qualcomm’s Snapdragon 810 processor and Ericsson Long Term Evolution (LTE) software designed to support the company’s RBS6000 family of base transceiver stations (BTS) for macro and small-cell networks. During the live test, the Swedish vendor aggregated 20MHz of LTE FDD spectrum with 20MHz of LTE TDD spectrum, supporting peak data rates of up to 260Mbps.

Commenting on the trial, Tay Yeow Lian, managing director for SingTel Networks division, said: ‘We are using dual-layers of LTE FDD with LTE-Advanced (LTE-A) carrier aggregation, and we know the performance of our mobile network is critical to ensuring that our customers have a great experience on their smartphones and tablets … We will continue to explore the future option of bundling TDD spectrum into LTE CA to expand network capacity, allowing our customers to enjoy consistent high data speed download even at high traffic areas.’ Industry watchers expect that commercial devices capable of supporting FDD/TDD CA will be available from next year.
