For transmitters rated at a maximum output power not listed above the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
