900MHz Frequency Key (Golden Setting)
Setting Description
Options 0 to 9
A to E
Important!: Do NOT use Frequency Key E with the 915 to 928 MHz, 916
to 920 MHz, and 921 to 928 MHz hop tables.
Terminal Menu (3) Edit Radio TransmissionCharacteristics > (0) FreqKey
Description: l Fifteen choices are available for the Frequency Key (0 to 9 and A to E)
setting, representing 15 different pseudo-random hop patterns.
l Hopping patterns minimize the interference with other FreeWave radios
operating in the area.
Example: If 10 pairs of FreeWave radios are operating on different
networks in close proximity, setting a different Frequency Key value
reduces the chance that radios hop to the same frequency at the same
time.
If two networks were to hop to the same frequency, the next hop would be
to a different frequency for both networks.
Gain additional network separation by adjusting the Max Packet
Size and Min Packet Size parameters.
Note: Use the Hop Table Version, Hop Table Size, and Frequency
Zone parameters to define more network differentiation by limiting the
number and location of frequencies the radios may hop in the 902 to 928
MHz band.
Important!: 900MHz radios do NOT use the Hop Frequency Offset
setting.
2.4.3. 900MHz Frequency Zones
Note: In MultiPoint networks, this setting needs to only be set on the Master.
In a Point-to-Point network, the Master and the Slave must have matching Frequency Zone
settings.
Important!: Frequency Zones are NOT valid if Single is selected in the 900MHz Channel Select
Parameters (on page 44).
