Abstract
A mixed data unit for use in a wireless network may include a first portion having information that is coded over a single frequency channel and a second portion having information that is coded across multiple frequency channels. In at least one embodiment, the first portion includes duration related information that may be used by legacy client devices within the network to determine a duration for which the legacy device is to remain quiet to avoid packet collisions in the network.
