Notes for Table 10-4
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 of 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 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.
