900MHz Frequency Zones

Zone
Description: Divides the available band (902 MHz to 928 MHz) into smaller bands.
In this case 16 smaller bands each consisting of 5, 7, and 8 frequency channels
depending on the frequency zone.
l These 16 zones are stored in a binary word, which is made up of 16 bits
numbered 0 to 15.
l Displayed in LSB to MSB, these bits directly represent the zones that the
radio operates on from lowest frequency to highest.
l A value of 1 in the bit sequence instructs the radio to operate within the
represented band.
l A value of 0 bypasses the represented band. This feature should only be
used with the standard hop table.
Caution: Set the Hop Table Version to 902 to 928 MHz when using
Frequency Zones.
If another Hop Table Version is selected, the limitations of that
selection are also applied to the hopping pattern.
Example: If 916 to 920 is used as the Hop Table Version, only the
middle of the band is available in the pattern.
Then, if Frequency Zones 5, 6, 7, 8, and 9 are set to 0, no allowable
frequencies are available for the radio to use.
900MHz Frequency Zones Table
Warning! FCC regulations require a minimum of 50 separate channels be used within a hop
pattern.
Use the 900MHz Frequency Zones Table to determine the number of frequency zones
required for legal FCC use.
Example: Using zones 1 to 7 is equal to 49 channels; this is NOT legal according to the FCC.
Using zones 0 to 6 is equal to 50 channels; this is legal according to the FCC.
