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.
Notes
1. At 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
2. The ISM (industrial, scientific, and medical) bands between 150kHz and
80MHz are 6.765MHz to 6.795MHz; 13.533MHz to 13.567MHz, 26.957MHz
to 27.283MHz; and 40.660MHz to 40.700MHz.
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.
4. These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
5. Transmitters/antennas of this power-level are most likely mounted
on an emergency vehicle chassis. The distances cited here are for
open field. For an external antenna, the separation distance is most
likely shorter.
