Sri Lanka Telecom (SLT), the largest wireless broadband operator in Sri Lanka, in partnership with ZTE completed a PoC verification test for LTE-A Pro, in Colombo.
SLT which started building its TD-LTE networks in 2014, used ZTE's eWBB solution that incorporates a range of key technologies like Massive MIMO, CA, uplink and downlink high-order modulation, and 4x4 MIMO.
According to ZTE, the eWBB solution can increase the network capacity and performance dramatically, with a wide range of key technologies like 256QAM, 4x4 MIMO, CA, MU-MIMO, and Pre5G Massive MIMO.
This LTE-A Pro test, which was carried out in a network environment with real-world scenarios, showed that the eWBB solution greatly lowered network transport requirements, making it possible to enhance 4G inter-cell performance. In a real commercial network, the ZTE Massive MIMO solution offers a peak rate of 720 Mbps per carrier, six times faster than a traditional TD-LTE carrier.
In this round of tests, ZTE claims that it was the only vendor that offered a peak throughput of over 1 Gbps, using 4CC, 256QAM, and 4x4 MIMO.
