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. The ISM (industrial, scientific and medial) bands between 150 kHz
and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz;
26.957 MHz to 27.283 MHz; and 40.660 MHz to 40.700 MHz.
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.
NOTE 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.
