For transmitters 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 1: From 80 MHz to 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
Recommended separation distances between RF wireless communications equipment
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a minimum distance between RF wireless communications equipment and the
device as recommended below, according to the maximum output power of the communications equipment.
