For transmitters rated at a maximum output power not listed above, the separation
distance can be estimated using the equation in the corresponding column, where P is the
maximum output [power rating of the transmitter in watts (W)] according to the transmitter
manufacturer.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and refl ection from structures, objects, and people.
