For transmitters whose maximum rated power is not in the above table, the recom‐
mended safe distance d in meters (m) can be calculated using the equation for the
respective gap, where P is the maximum rated power of the transmitter in Watts (W)
according to the manufacturer's information.
NOTE 2: These guidelines may not be applicable in every case. The spread of
electromagnetic waves is absorbed and reflected by buildings, objects and people.
Comment 1: To calculate the recommended safe distance from transmitters with a
frequency range of 80 MHz to 2.5 GHz, an additional factor of 10/3 was used to
reduce the probability that a mobile unintentionally brought into the patient area
would cause malfunction.
