Executive Summary

One of the challenges in today's wireless networks is to provide appropriate throughput for data and multimedia application. The physical data rate enhancements can be achieved through new physical capabilities, however to achieve high efficiency and to improve the throughput at the Medium Access Control (MAC) layer, new and innovative MAC mechanisms are required. The disgraceful overhead occurs at the MAC layer prevents the WLANs from achieving desirable performance, this problem becomes more severe in the very high-speed WLAN. The authors will consider the potential benefits of frame aggregation in order to enhance the throughput.
