Time-Division Multiple Access

Time-Division Multiple Access (TDMA) is a channel access method utilised in shared medium networks such as early cellular networks (2G GSM). This method allows several users to share the same frequency band by dividing the signal into different time slots. Each user is allocated a unique time slot during which they can send and receive data, thereby preventing interference from multiple simultaneous transmissions. This method is particularly effective in telecommunication systems, as it allows for the efficient use of bandwidth and synchronisation of communication. The primary advantage of TDMA is the ability to carry many signals over a single transmission channel. TDMA also has its limitations. The main disadvantage is that users need a significant amount of processing power to recover the signal due to the time division. Additionally, the users must be synchronised precisely to prevent overlap and maintain the integrity of the signal.
