Some of the key changes/additions are as follows:
-A new definition of the medium access control (MAC) layer management entity (MLME) service access point (SAP) so that it now provides a consistent interface. -A new acknowledgment (ACK) policy, implied-ACK, which allows polling and a more efficient use of channel time. -An additional data frame, the logical link control/subnetwork access protocol (LLC/SNAP), which allows multiple protocols to share a single data connection. -A method for relinquishing time in a channel time allocation (CTA) to allow another device (DEV) time to transmit data. -The allowing of a DEV to return information about a signal quality of a received packet in an ACK frame. -The ability to assign device identifiers (DEVIDs) to group addresses to allow multicast connections. -Faster recovery of network operations when the piconet coordinator (PNC) abruptly disconnects with the conditional handover and the next PNC processes. -A protocol by which a DEV can request that the PNC place an application-specific information element (ASIE) in the beacon. -The allowing of multiple contention periods during a superframe. |
