For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (m) can be determined
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
An additional factor of 10/3 has been incorporated into the formulae
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 3
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
