Executive Summary

This paper examines the peak performance of an 802.11n system with respect to the achievable throughput and the authors decompose the gains observed due to the various PHY/MAC layer features offered from 802.11n. The results show that while the MIMO PHY and channel bonding offered from 802.11n increase the PHY data rate, packet aggregation and block acknowledgment are required to achieve throughput closer to the latter.
