According to foreign media reports, Sri Lankan Telecom (SLT) completed a new round of proof-of-concept testing of LTE-A Pro technology in Colombo.
The operator cooperated with suppliers such as ZTE to test LTE-A Pro under the real-world existing network environment.
ZTE said the company is the only vendor that uses quad-carrier aggregation, 256 quadrature amplitude modulation (256 QAM) and 4x4 MIMO (4x4 MIMO) to deliver peak throughputs in excess of 1 Gbps.
The vendor provided its eWBB solution for testing. ZTE's Massive MIMO products can deliver peak rates of 720 Mbps per carrier in real commercial networks, six times faster than traditional TD-LTE.
Sri Lankan Telecom launched its TD-LTE service in 2014 and has been working hard to improve its network capacity and quality as its subscriber base grows
Given the high cost of fixed broadband coverage, Sri Lanka Telecom plans to use eWBB solutions to provide broadband services to a large number of Sri Lankan citizens still unable to connect to the Internet, which is also in line with the government's national broadband policy
