MIMO stands for multiple input, multiple output.5G will use ‘massive’ MIMO antennas that have very large numbers of antenna elements or connections to send and receive more data simultaneously. The benefit to users is that more people can simultaneously connect to the network and maintain high throughput.
The overall physical size of the 5G massive MIMO antennas will be similar to 4G, however with a higher frequency, the individual antenna element size is smaller allowing more elements (in excess of 100) in the same physical case.
5G User Equipment including mobile phones and devices will also have MIMO antenna technology built into the device for the mmWave frequencies.
