Implementation of 324Mbps WLAN equipment with MAC frame aggregation for high MAC-SAP throughput

We developed a high speed wireless LAN prototype in the 5GHz band. Maximum transmission rate of the developed WLAN equipment was 324Mbit/sec using 6 multi-channels of 802.11a. We proposed a novel frame aggregation scheme to improve MAC efficiency. The proposed frame aggregation scheme had a feature of an adaptive aggregation size selection depending on thewireless channel conditions and application requirements. Throughput performance was obtained from simulation using a multiple station system with the proposed frame aggregation. A throughput of more than 150Mbit/sec was achieved with an evaluated system of 10 STAs. We also found that the measured throughput of more than 170Mbit/sec was achieved using the proposed frame aggregation.
