 Quality of Service (QoS)
Quality of Service is a measure of network performance that reflects the network's transmission quality and service availability. QoS can come in the form of traffic policy in which the transmission rates are limited, thereby guaranteeing a certain amount of bandwidth will be available to applications. Or QoS may take the form of traffic shaping, which are techniques to reserve bandwidth for applications but not guarantee its availability.
The QoS standard for IEEE 802.11 wireless LANs, called 802.11e, is under development but won't be finalized until 2004 or later.
