What is MU-MIMO?
MU-MIMO, short for Multi-User Multiple Input Multiple Output, is an advanced technology designed to improve wireless communication by allowing multiple devices to communicate simultaneously with a single wireless access point (AP). While traditional Wi-Fi technology, known as Single-User MIMO (SU-MIMO), can only serve one device at a time, MU-MIMO enhances network efficiency by enabling concurrent data transmission to several devices.
This innovative feature is a part of the Wi-Fi 5 (802.11ac) and later Wi-Fi 6 (802.11ax) standards, supporting greater user capacity and optimizing the way wireless signals are sent and received.
How Does MU-MIMO Work?
To understand how MU-MIMO works, it is important to review the basic principles behind MIMO technology. Let’s break it down:
1. Basic Principles of MIMO
MIMO is a method that employs multiple antennas at both the transmitter (router) and receiver (device) ends. By utilizing multiple antennas, MIMO can send and receive more information simultaneously, thus increasing the data throughput and improving the signal quality.
2. The Role of Spatial Multiplexing
MU-MIMO takes this concept further by introducing spatial multiplexing. This technique allows the router to send separate data streams to different devices using the same frequency band. Each data stream travels in its own spatial path, effectively allowing devices to receive their data at the same time without interference.
Spatial Streams
In MU-MIMO, the number of spatial streams that can be transmitted simultaneously is determined by the number of antennas on the router and the client devices. For example, a router with four antennas can transmit data to four devices at the same time, each receiving its distinct data stream.
