According to the report, field test results in live commercial networks have recently shown that 4x4 MIMO can effectively improve network performance and user experience, and the device ecosystem is rapidly developing to support 4x4 MIMO.

Guang Yang, Director of Wireless Networks and Services, said, "Field test results prove that 4x4 MIMO can be an efficient tool for mobile operators to improve network capacity and user experience to meet fast growing mobile data demands. Because 5G coverage will be limited in its early phase, customer's seamless mobile broadband experience will still rely on the underlay 4G network. The performance of the underlay 4G network will be important for the success of early 5G deployment."

Christopher Taylor, Director of the RF & Wireless Components advisory service, added, "Gigabit LTE using 4x4 DL MIMO is at the leading edge today. The ecosystem is developing rapidly, with new phone models supporting 4x4 MIMO arriving on retail shelves every month. More phone chip suppliers will soon enter the market with LTE radio modems that support 4x4 DL MIMO as well as advanced carrier aggregation with five CCs, LAA / LTE-U and eventually millimeter wave 5G. This will benefit the entire ecosystem from operators to consumers with more availability, lower prices, and new services."
