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.
NOTE 3: An additional factor of 10/3 is used in calculating the recommended separation distance for
transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency
range 80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable communications
equipment could cause interference if it is inadvertently brought into patient areas.
NOTE 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
