IEC60601-1-2: Table 206
Recommended separation distances between portable and mobile RF
communications equipment and the device
These devices are intended for use in an environment in which radiated RF
disturbances are controlled. The customer or the user of the device can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and
the device as recommended below, according to the maximum output power of
the communications equipment

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 for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
