Abstract—We developed a high speed wireless LANprototype in the 5GHz band. Maximum transmission rate ofthe developed WLAN equipment was 324Mbit/sec using 6multi-channels of 802.11a. We proposed a novel frameaggregation scheme to improve MAC efficiency. Theproposed frame aggregation scheme had a feature of anadaptive aggregation size selection depending on thewireless channel conditions and application requirements.Throughput performance was obtained from simulationusing a multiple station system with the proposed frameaggregation. A throughput of more than 150Mbit/sec wasachieved with an evaluated system of 10 STAs. We alsofound that the measured throughput of more than170Mbit/sec was achieved using the proposed frameaggregation.
