Do you know the difference?

I have found many people having problem with the differences between them while it’s important to know the difference between Multiplexing and Multiple Accessing. Multiplexing refers to information transmission from one place to another place whereas Multiple Access refers to the technique by which the information is shared from one place to another.

Multiple access uses network as a resource while multiplexing uses link as a resource. Multiple access uses matrix as its terminal connectivity while multiplexing uses terminal connectivity by the use of point to multi point for the connection. The control is distributed in the multiple access while the control is at terminal in Multiplexing.

Multiplexing or muxing is a method of sending or transmitting multiple signals or streams of information over a communication link simultaneously in the form of a single, complex signal. The receiver then picks up the separate signals, a process called demultiplexing or demuxing. There are two reasons why networks use multiplexing.

One is to make it possible for any network device to talk or communicate to any other network device without the need to dedicate a connection for every pair. Two is to make a scarce or expensive resource stretch further like when sending many signals down each cable or fiber strand running between major metropolitan areas or across one satellite uplink.

Multiple access is a method that allows multiple mobile users share the allocated spectrum in the most effective way. Because spectrum is limited, sharing is required to enhance the overall capacity over a geographical area. This is performed by allowing the available bandwidth to be used simultaneously by different users.

A cellular system splits or divides any allocated area into cells wherein a mobile unit in every cell can communicate with a base station.
