MTN South Africa in partnership with Qualcomm Technologies and Huawei has recently completed 4x4 MIMO field trial in a live network, where the average download throughput increased by 74% compared to traditional LTE 2x2 MIMO.
Based on that excellent performance of the technology, MTN plan to rollout South Africa's largest 4x4 MIMO network in 2017 to provide users with the best 4.5G experience.
MTN South Africa began to roll out their LTE network in 2012. Average growth rate of mobile data traffic in the whole network reaches 79%. The growing demand for data service needs more capacity to allow for enhanced user experiences.
MIMO technology allows operators to significantly improve network capacity and user experience, and coverage without adding spectrum or adding new sites. Compared with traditional 2x2 MIMO, the field trial demonstrated that the average download throughput of 4 receiver terminal (4x4 MIMO) increased by 74% and 2 receiver terminal (4x2 MIMO) increased by 26%, which showed deploying higher-order MIMO can alleviate network traffic congestions.
