ABSTRACT:
A wireless LAN having a plurality of wireless phones with enhanced medium access control which enables QoS functionality and being further modified to provide priority transmission of frames of information are associated with one or more access points that have also been enhanced with QoS functionality. The wireless phones are utilized to transmit and receive frames of voice information to and from other wireless phones via the access points. The WLAN also includes a router that operates to forward frames of voice information from one access point to another or to an IPPBX. SVP functionality located on a network server or on each wireless phone assists to facilitate the efficient reception of frames of voice information by the wireless phones. The modifications made to each wireless phone enables them to transmit frames of voice information on a priority basis with respect to all other wireless phones associated with a particular access point.
