The A-Packet is structured to carry the native protocol data and all information that the A-PHY Data Link Layer requires to perform its functions efficiently.
The A-Packet has following features and functions:
- Downlink and uplink use the same packet structure.
- The structure is optimized supporting multiple protocol aggregation with minimal overhead and latency.
- The A-Packet header contains all required information (e.g., QoS, Priority, Destination, Protocol Type).
- The A-Packet structure:
- Header: 8 byte including MC (message counter) and header CRC (Cyclic Redundancy Check)
- Tail: 4 Byte (CRC-32)
