Section 3 - Viewing Access Point Status
A TSPEC is a trafîšżc speciîšżcation that is sent from a QoS-capable wireless client to an AP requesting a certain
amount of network access for the trafîšżc stream (TS) it represents. A trafîšżc stream is a collection of data packets
identiîšżed by the wireless client as belonging to a particular user priority. An example of a voice trafîšżc stream is a Wi-Fi
CERTIFIED™ telephone handset that marks its codec-generated data packets as voice priority trafc. An example of
a video trafîšżc stream is a video player application on a wireless laptop that prioritizes a video conference feed from a
corporate server.
