Massive MIMO (Multiple Input Multiple Output) is an enhancement to the 5G network whereby enormous antennas (i.e., as big as a refrigerator) are being placed on towers. This technology is one of the keys to unlocking better 5G data rates, throughput, and spectral efficiency. Indeed, massive MIMO accomplishes this by adding a much greater number of antennas on the tower base station.
The primary benefits of massive MIMO to the network and end users are i) capacity increases and ii) coverage improvements. Ultimately, better capacity and coverage lead to a superior user experience. At the same time, this technology reduces wireless network interference, which further improves the user experience.
