Notes:
•Apacket is the basic unit of transmission. A packet may or may not contain a payload.
A payload is user data, which may be an Ethernet frame or a logical link layer control
message.
• WEP is not supported in this release.
• Registration occurs once per EUM and/or CCU boot time. Deregistration may occur if
an EUM is not authorized (a registration/deregistration request pair occurs periodically
while that EUM is powered ON) or if the EUM does not respond to multiple
consecutive polls, such as when it is powered OFF.
• Association occurs when there is traffic to send to or from an EUM. Disassociation
occurs if there is no traffic to or from an EUM for a short period of time.
