(3) FREQUENCY ZONE
Frequency Zone: The idea of frequency zoning is to divide the available band (902MHz to 928 MHz) into 16
smaller bands each consisting of 5, 7, or 8 Frequency channels depending on the frequency zone. These
16 zones are controlled by selecting option 3 and then entering a 1 (Enable) or a 0 (Disable) next to the
appropriate zone number. This can be seen in the screen shots below. Every other zone is disabled,
thereby reducing the number of available channels for the radios to hop upon. For optimum network
performance the entire network must be set to the same Frequency Zone settings. Also, this feature should
only be used with the standard hop table.
