Advanced MIMO boosts 4G performance and helps operators to prepare 5G

Christopher Taylor of Strategy Analytics

Recent field test results in live commercial networks prove that 4×4 MIMO can effectively improve network performance and user experience, and the device ecosystem is rapidly developing to support 4×4 MIMO, concludes Strategy Analytics in the report “4×4 MIMO Boosts 4G and Gives Consumers a Taste of the Gigabit Experience.

The report from the Strategy Analytics Networks and Service Platforms, and RF & Wireless Components advisory services, predicts 4×4 MIMO will be gaining momentum in 4G infrastructure market and becoming a mainstream configuration of flagship smartphones.

Guang Yang, director of wireless networks and services, said “field test results prove that 4×4 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 4×4 DL MIMO is at the leading edge today. The ecosystem is developing rapidly, with new phone models supporting 4×4 MIMO arriving on retail shelves every month.

More phone chip suppliers will soon enter the market with LTE radio modems that support 4×4 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.”
