ZTE has announced a partnership with Sri Lanka Telecom (SLT) to complete a PoC verification test in Colombo for its fixed-wireless eWBB solution using LTE-A Pro.

In the test, ZTE used its TD-LTE eWBB solution that incorporates a range of technologies such as massive MIMO, carrier aggregation, uplink and downlink high-order modulation, and 4×4 MIMO. The eWBB test yielded a peak throughput of over 1 Gbps.

The LTE-A Pro test, which was carried out in a network environment with real-world scenarios, demonstrated reduced network transport requirements, making it possible to enhance 4G inter-cell performance, ZTE says. In a real commercial network, ZTE says its massive MIMO solution offers a peak rate of 720 Mbps per carrier, six times faster than a traditional TD-LTE carrier.

SLT has been deploying TD-LTE since 2014.

Sri Lanka has a population of 20 million. However,  the level of urbanization is low, and 80% of its population lives in the countryside. Low density leads to high costs in fixed broadband coverage.

ZTE says its eWBB solution employs a wireless approach that goes beyond geographical restrictions, and makes networks easy to plan and fast to build, bringing broadband networks to those unconnected.  Compared with ADSL and FTTx, the eWBB solution offers a higher transmission rate and a more cost-effective tariff, ZTE says.
