Frequency and Separation Guidelines
When using overlapping access points, you must provide
minimum physical separation between access point
antennas. The recommended minimum frequency
separation between frequencies used within an installation
is 200 KHz, with separation of 1 MHz preferred.
In some cases, you may need to use separations as small as
40 KHz (for 20 KHz spacings) or 50 KHz (for 25 KHz
spacings) because of regulatory limitations. In this case,
the physical separation between access point antennas
must be increased. The recommended minimum physical
separation between access points is 30 meters (100 feet).
Absolute minimum separations are based on frequency
separation, as indicated in the following chart.
