Modern communication technologies are steadily advancing the physical layer (PHY) data rate in wireless LANs, from hundreds of Mbps in current 802.11n to over Gbps in the near future. As. PHY data rates increase, however, the overhead of media access control (MAC) progressively degrades data. Abstract— We present a comprehensive set of measurements of a 2.4.
