Multiple Access Methods

One transponder serving several earth stations simultaneously

Multiple access is a radio transmission scheme that allows several earth stations to transmit in the same time span. This provides the way to network these stations together, either in a Star or a Mesh network.

Types of Multiple Access Methods

There are three types of Multiple Access Methods to understand:
  • Frequency Division Multiple Access (FDMA) - flexible and simple
  • Time Division Multiple Access (TDMA) - popular
  • Code Division Multiple Access (CDMA Spread Spectrum) - highly secure

This illustration shows how the most common Multiple Access Methods allow the capacity of a standard transponder to be shared.
