MIMO Technology

Multiple-Input Multiple-Output (MIMO) uses several transmit and receive antennas to improve communication performance without extra bandwidth or power.

It is a cornerstone of modern wireless standards like Wi-Fi, LTE and 5G.

Spatial Multiplexing and Diversity

MIMO exploits multipath propagation to send several data streams simultaneously over the same channel — a technique called spatial multiplexing that multiplies throughput. Spatial diversity, in contrast, sends the same data over multiple paths to improve reliability.

Massive MIMO scales this to hundreds of antennas, and beamforming concentrates signals toward intended receivers, reducing interference.

Frequently Asked Questions

MIMO uses multiple antennas at both transmitter and receiver to improve data rate and reliability without needing extra spectrum or power.

Spatial multiplexing sends different data streams to boost throughput, while diversity sends the same data over multiple paths to improve reliability.

MIMO is used in Wi-Fi, LTE, 5G, and WiMAX to deliver higher speeds and more reliable wireless connections.
