Nokia Networks and SK Telecom demo TD-LTE-A 3x CA with 256 QAM

11 Dec 2015

Finnish vendor Nokia Networks, working with South Korea’s largest cellco by subscribers SK Telecom (SKT), has demonstrated 428Mbps data transmission rates via what it claims was ‘the industry’s first TD-LTE 3x carrier aggregation [CA] with 256 quadrature amplitude modulation [QAM]’, utilising a Qualcomm Snapdragon X12 LTE modem from Qualcomm Technologies. Nokia Networks said it represented a ‘key development that lays the foundation for the introduction of TD-LTE in Korea’, adding that the trial verified the benefits of 3x CA combined with 256 QAM-capable devices, which can boost peak throughput from 110Mbps to 428Mbps, Nokia Networks has suggested that its Single RAN Advanced platform provides a strong foundation for SKT to construct an advanced TD-LTE network capable of addressing the demand for bandwidth-intensive services. Looking ahead, both companies have confirmed they will strengthen their collaboration by establishing a TD-LTE test bed and conducting trials of TD-LTE services.
