separation distance din 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 medical) 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 40,66 MHz to 40,70 MHz.
NOTE 3 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 2,7 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.
