AES-X260 UWB Hi Res, Low Latency Audio Interface

Scope: Describe the preferred way to implement connection management, assure consistent audio quality, and provide for interoperable audio and feature control sets for the MAC convergence and application layers of UWB devices intended for high-quality audio use. Provide extensions to IEEE 802.15.4ab standard which defines connection, operating features and command structure in order to provide an interoperable interface between UWB audio capture and playback devices.

J Green presented the aims of the project, which has been assigned to task group SC-02-02-B. Anyone interested in low latency high quality local area wireless audio is encouraged to join the task group.
