802.11b Access Point in Dependent Mode
A Harmony AP Controller handles all of the configuration and management of the
Access Points on the network. Each Access Point acts as an intermediary between its
mobile clients and the AP Controller, converting radio signals into Ethernet packets and
vice versa. The AP Controller monitors the Ethernet traffic and decides which packets
should be forwarded to mobile clients.
