AN OVERVIEW OF WIRELESS LOCAL AREA NETWORK

Wireless Local Area Network (WLAN) specification is approaching completion. In this seminar, protocol is explained, with particular emphasis on the medium access control sublayer. Performance results are provided for packetized data and a combination of packetized data and voice over the WLAN. Our performance investigation reveals that a network may be able to carry traffic with time-bounded requirements using the point coordination function. However, our findings suggest that packetized voice traffic must be handled in conjunction with an echo canceler.
