Access points are multiport (Ethernet-to-wireless) bridges, and because
wireless end devices operate similarly to other Ethernet devices, all your
existing Ethernet applications will work with the wireless network without
any special networking software. Any access point, except the root access
point, can concurrently receive hello messages on its Ethernet port, its
radio port, and its IP tunnel port. However, an access point can use only
one port to attach to the network. Port priorities are structured as follows:
1 Ethernet
2 IP tunnel
3 Radio
Unlike the physical Ethernet and radio ports, the IP tunnel port does not
have its own output connector. It is a logical port that provides IP
encapsulation services for frames that must be routed to reach their
destinations. Once frames are encapsulated, they are transmitted or
received through the Ethernet or radio port.
Wireless end devices may use power management to maintain battery life.
These end devices periodically wake up to receive frames that arrived while
their radio was powered down. The access point automatically provides a
pending message delivery service that holds frames until the end device is
ready to receive them.
