Recommended separation distances
For portable and mobile RF communication equipment and the EUT.
The EUT is intended for use in the electromagnetic environment in which radiated RF
disturbances are controlled. The customer or user of the EUT can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communication equipment (transmitters) and the EUT as
recommended below, according to the maximum output power of the communications
equipment.

Table 6 of DIN EN 60601-1-2:2007 (IEC 60601-1-2:2007)
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres [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 higher frequency range applies.
Note 2:
These guidances may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
