8.4.5 Advantages And Disadvantages Of TDMA
Advantages:
- Deterministic isolation: Users are separated in time with no simultaneous multi-carrier interaction.
- Efficient amplifier utilization: Only one carrier occupies the channel at a time, reducing intermodulation constraints.
- Flexible capacity allocation: Slot duration and number can be adjusted to meet traffic requirements.
- Compatibility with digital systems: Naturally suited to burst-mode digital transmission and packet aggregation.
- Predictable quality of service: Scheduled access enables latency and throughput guarantees.
Disadvantages
- Stringent synchronization requirements: Precise timing control is necessary to prevent burst overlap.
- Guard-time overhead: Guard intervals reduce net spectral efficiency.
- High instantaneous bit rate: Burst transmission requires higher peak data rates and power.
- Buffering requirements: Data must be stored between bursts, increasing system complexity.
- Control signaling overhead: Dynamic allocation requires coordination and scheduling mechanisms.
