• Single Collision Frames
Packets that had a single collision during transmission requiring a single re-transmission.
• Multiple Collision Frames
Packets that had a multiple collision during transmission requiring a multiple re-
transmission.
• Late Collisions
A packet that was not delivered to the transceiver on time.
• Internal MAC Transmit Errors
An internal error within the Medium Access Protocol during the transmission process.
• Internal MAC Receive Errors
An internal error within the Medium Access Protocol during the receiving process.
