International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / IEEE 802.11e is an amendment of the medium-access control (MAC) layer of the standard for
wireless local area networking IEEE 802.11. The goal of 802.11e is to provide 802.11 networks with
Quality of Service (QoS). 802.11 has three physical layers (PHY) of practical importance: 802.11b,
802.11a, and 802.11g. 802.11a and 802.11g provide data rates between 6 and 54 Mbps, and 802.11b
provides data rates of 5.5 Mbps and 11 Mbps. However these data rates are not the actual throughput.
The actual throughput that a user will experience will be lower. The throughput depends on both the
PHY and MAC layers. It is important to estimate what exactly is the throughput when the physical
layer is 802.11a, 802.11b, or 802.11g, and the MAC layer is 802.11e. In other words, how does
providing QoS change the throughput for each of the three physical layers? In this paper we provide
answers to this problem. Analytic formulae are derived. The maximum achievable throughput and
minimum delay involved in data transfers are determined. The obtained results have further
significance for the design of high-throughput wireless protocols.
