MASSIVE MIMO TECHNOLOGY

​

Massive multiple-input, multiple-output, or massive MIMO, is an extension of MIMO, which essentially groups together antennas at the transmitter and receiver to provide better throughput and better spectrum efficiency. This method’s ability to multiply the capacity of the antenna links has made it an essential element of wireless standards including 802.11n (Wi-FI), 802.11ac (Wi-Fi), HSPA+, WiMAX and LTE.

 

Moving from MIMO to massive MIMO involves making a clean break with current practice through the use of a large excess of service antennas over active terminals and time-division duplex operation.

 

Extra antennas help by focusing energy into ever smaller regions of space to bring huge improvements in throughput and radiated energy efficiency.
