Installing the XS-3900 23
Custom Coverage
Where there are highly reflective objects in close proximity to the XS-3900, you
can turn off specific radios to avoid interference and feedback.

Calculating Areas
Before we discuss cell sizes, it is useful to know how to calculate the area of a
circle (because the XS-3900 radiates a full 360 degrees). The area of a circle is equal
to pi (
π) times the square of the radius, where pi is equal to 3.14. The following
graphic calculates the area of a circle with a radius of 20 feet.
