Table 3-1 shows the frequency range covered by each zone for
900 MHz radios. Table 3-2 shows the same information for
2400 MHz radios.

(2400 MHz systems)
NOTE:
Use caution when changing the operating band of 2.4 GHz
radios. If a Remote and AP are set to different bands, and
communication is lost with the AP, you might have to visit the
Remote site to restore operation.
3.6 CONFIGURING THE SERIAL
INTERFACES
3.6.1 Overview
To understand the operation of the radio system, it is helpful to visualize
the AP and the Remotes as being in a single box, with the AP ports on
one side and all of the Remotes on the other side (see
Figure 3-21 ). In
practice, the radios are typically separated by considerable distances, but
thinking of them grouped in the same box is helpful for this discussion.
Most data routing is done at the AP, so you must also perform the
majority of system configuration at the AP. The AP requires
configuration of its local interfaces (Ethernet or Serial) and knowledge
of its remote interfaces, which are physically located at the Remote
radios. There are also a few parameters that you can configure at the
individual Remote radios.
