This amendment provides corrections and optimizations to IEEE Std 802.15.3-2003. The management service access points (SAPs) have been completely updated to create a consistent, logical interface. As a consequence, most of the message sequence charts (MSCs) in the medium access control (MAC) functional specification have been updated as well. Channel time usage is more efficient with the addition of multiple contention periods, releasing channel time, implied acknowledgment, and mullticast groups. (The PDF of this standard is available at no cost.

This amendment contains changes to the IEEE Std 802.15.3 required to improve implementation and interoperability. This will include minor optimizations while preserving backward compatibility. In addition, this amendment will correct errors, clarify ambiguities, and add editorial clarifications.

The purpose of this amendment is to improve the ability of IEEE Std 802.15.3 to support emerging wireless multimedia applications; e.g., multimedia streaming, time synchronization, low latency data transfer, and peripheral connectivity.
