Why is Multiplexing Needed in Data Communication Systems?

Why is Multiplexing Needed in Data Communication Systems? The range of frequencies is limited, but the number of devices using the system fluctuates. One way to separate the different data streams is each one have its’ own frequency (like different radio or TV stations broadcasting).

This works fine when there are a limited number of users. Radio and TV are one-way, so there are a limited number of stations broadcasting. But with cell phones, broadband wireless and other services, the frequency spectrum is crowded.

To have multiple users share the same frequency without walking over each other, multiplexing is used so that each user gets its data transmitted in packets. There are various methods of multiplexing available.
