Spatial multiplexing is a MIMO wireless protocol that sends separate data signals or streams between antennae to enhance wireless signal performance or functionality. It is a type of “spatial diversity” and an engineering trick that helps to increase the possibilities for various types of end-to-end transmission.
In spatial multiplexing, multipath propagation involves multiple-input/multiple-output or MIMO wireless technology setups – the transmit stations use multiple transmit and receive antennas to produce sophisticated signal results. A wireless access point uses multiple radios to enable more than one unique data stream to go between the transmitter and receiver. This increases throughput and is a common technique in order to innovate with wireless setups.
