According to foreign media reports, South Africa's MTN has announced that it has joined hands with Qualcomm Technologies and Huawei to complete a field test of 4*4 MIMO technology in a live network.

Compared with the traditional 2*2 MIMO LTE technology, the average download throughput of this field test increased by 74%.

The test results show that the deployment of higher-order MIMO can alleviate network traffic congestion; MTN SA is currently planning to officially roll out 4*4 MIMO technology on its South African network.

Giovanni Chiarelli, Chief Technical Information Officer of MTN South Africa, said: "MTN is confident in MIMO technology. We plan to launch the largest 4*4 MIMO 4.5G network in South Africa and introduce the latest 4*4 MIMO terminals so that users can enjoy the best 4.5G experience in 2017."
