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