TDMA, or Time Division Multiple Access, is a communication method that allows multiple users to share the same frequency channel by dividing the time into distinct intervals. Each user is assigned a specific time slot during which they can transmit their data, ensuring that signals do not interfere with one another. This technique is commonly used in mobile phone networks and satellite communications. By allocating time slots, TDMA increases the efficiency of the available bandwidth and reduces the chances of collisions between data transmissions. This organized approach helps maintain clear communication, making it a popular choice for various wireless technologies, including GSM and IS-136 systems.
