Review on QoS issues in IEEE 802.11 W-LAN

QoS is a key consideration for wireless IP networks and implementation of QoS for supporting voice, video, and multimedia services in general bring a number of difficulties that have to be resolved. In particular, because network bandwidth, timely delivery of multimedia data and wireless fading and high BER in IEEE 802.11 wireless LAN (W-LAN) applications and services is a challenging problems, various researches and trials have been made to enhance the quality of W-LAN application services. This paper discusses the primary issues on QoS in WLAN applications and services and suggests the way of development to enhance the quality of services in W-LAN services
