Topology: TDMA PTP & PTMP

TDMA vs 802.11 CSMA

- Media access is scheduled by TDMA AP, this eliminates hidden node problem and allows to implement centralized media access policy.

- There are no per-frame ACKs in TDMA AP, this significantly improves throughput, especially on long distance links where data frame and following ACK frame propagation delay significantly reduces the effectiveness of media usage.
