Patent ID: 6934752

Claim:
An interface between a wireless network component and a wireless medium, the interface communicating multimedia data streams as defined by a networking protocol that includes definitions of quality of service enhancements to provide reliable communications of said multimedia data streams, the quality of service enhancements comprising a capability information field and a multimedia control field within a media access control frame and including a frame position sub-field, pad byte sub-field, a stream index sub-field, a basic service set identification sub-field and a time stamp sub-field; and wherein the capability information field consists of a multimedia capability bit to indicate whether a device is multimedia enhanced, a proxy point coordinator bit to indicate whether a device can provide proxy services, a alternate point coordinator capability bit to indicate whether a device can be an alternated point coordinator, and a channel sharing bit to indicate whether basic service set is sharing a channel with other overlapping basic service sets; and wherein the multimedia control field consists of 32 bits; wherein the 32 bits of the multimedia control field consists of five sub-fields; and the five sub-fields consist of: a first 2-bit sub-field indicating a frame position within a series of frames, a second 2-bit sub-field indicating a number of bytes padded in a frame to make an entire frame 4-byte aligned, a third 4-bit basis service set identification sub-field indicating when overlapping subnets need to operate in a same channel, a fourth 8-bit sub-field indicating an index number uniquely identifying the multimedia data streams, in which all values of the index are dynamically assigned and used, a fifth 16-bit time stamp sub-field used to provide support for synchronization of any two streams originating from a device.
