Each of the above parameters are set in the AP by the system administrator and cannot be controlled at the SU. These
parameters will be covered in greater detail later in this text.
When power is first applied to a properly installed SU, it will scan all available channels, searching for an AP with matching
Base ID and MAC in its SU Database. The SU will then stop on that channel and respond to the AP using maximum RF
power. Before the AP can add the SU to the polling list, it must authenticate the SU by verifying the MAC address, and
performing a ranging operation to the SU.
Upon successfully locating and ranging the SU, the AP will then add the SU to the normal polling list and, it will adjust the
RF transmit power in the SU based on the Target RSSI parameter in the AP. This process is referred to as “power leveling”.
