A TSPEC is a traffic specification that is sent from a QoS-capable wireless client to a WAP
device requesting a certain amount of network access for the Traffic Stream (TS) it represents.
A traffic stream is a collection of data packets identified by the wireless client as belonging to
a particular user priority. An example of a voice traffic stream is a Wi-Fi CERTIFIED
telephone handset that marks its codec-generated data packets as voice priority traffic. An
example of a video traffic stream is a video player application on a wireless laptop that
prioritizes a video conference feed from a corporate server.
