IEC60601-1-2:
Recommended separation distances between portable and mobile RF communications equipment
These devices are intended for use in an environment in which radiated RF disturbances are controlled. The
EN
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 re-
commended 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.
