G: Separation Between Devices Using Adjacent Channels
62 Verint Video Solutions
If using adjacent frequency channels in a non-DFS environment, you should respect
guidelines relative to the minimum separation between device antennas. The guidelines
apply to the S1100, S1100w, and S3100 devices.
In the 2.4 GHz band, the adjacent channel term applies only to the three non-overlapping
channels (1, 6, and 11).
The presented figures represent worse case scenarios. By respecting them, you can assume
that there will not be radio interference between the devices.
Three physical setups are covered:
The minimum separation between devices using adjacent channels is:
If you are using other antennas with narrower beam widths, the distances may be reduced.
For assistance, contact the Verint Video Solutions project engineering group.
To help you plan your systems, here are installation scenarios that respect the limitations.
These scenarios include the frequency band and channel.
