SDMA

Space-Division Multiple Access (SDMA) is a method of wireless communication that separates signals based on the physical space they occupy. It is a channel access method based on creating parallel spatial pipes (focused signal beams) using advanced antenna technology next to higher capacity pipes through spatial multiplexing and/or diversity. This technique enables multiple users in the same frequency band to transmit simultaneously without interfering with each other. SDMA utilises the spatial separation between transmitters and receivers, often achieved through advanced antenna technology. This method is particularly beneficial in improving the capacity of wireless communication systems, as it allows for the efficient use of available bandwidth.
