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.

58. A method for avoiding a collision in a wireless network comprising:
-
sensing a transmitted data unit within a first wireless client device that is operative within a single frequency channel;
reading a first portion of the transmitted data unit to determine that the transmitted data unit is a mixed data unit that includes a second portion that is coded across multiple frequency channels and that cannot be read by the first wireless client device;
reading duration related information from the first portion of the transmitted data unit to determine a duration for which the first wireless client device is to remain quiet; and
remaining quiet for the indicated duration. - View Dependent Claims (59, 60, 61, 62)
