What is TDMA?

Time-Division Multiple Access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. Users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g., radio frequency channel) while only using its assigned time slot. TDMA is commonly used in mobile radio systems, such as GSM, and satellite communication.

TDMA Competitor Technologies

FDMA

Frequency Division Multiple Access is a channel access method that divides the available bandwidth into frequency channels. It's a competitor as it provides an alternative method for multiple users to access a single channel.
