When attempting confirmed message delivery in a Private DataTAC system, the Radio Data - Link Access Procedure air interface protocol is responsi- ble for the Automatic Retransmission reQuest (ARQ) reliability mechanism for the network. For confirmed message packets, this means re-transmit- ting packets when requested by the receiving device or when no acknowledgment is received indicating that the packet was received error free. Unfortunately, the retry number is valuable informa- tion that is not included in the packet header and could be used to increase network performance and manageability.
