Time Division Multiple Access (TDMA) is a communication method that allows multiple users to share the same frequency channel by dividing transmission time into small, repeating time slots. Each user is assigned a specific time slot and can transmit data only during that period, taking turns in rapid sequence. This prevents signals from overlapping and causing interference. TDMA is commonly used in digital cellular networks, such as GSM, as well as in satellite and radio communication systems. By efficiently allocating time slots, TDMA improves bandwidth usage and supports multiple connections over a single channel while maintaining reliable and organized data transmission.
