For transmitters for which the maximum nominal output is not indicated in the above
table, the recommended safety distance d in meters (m) can be determined using
the equation belonging to the respective column whereas P is the maximum nominal
output of the transmitter in watts (W) acc. to manufacturer's specification.
NOTE 1
With 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2
These guidelines may not be applicable in all cases. The emanation of electromagnetic
waves is affected by absorption and reflection of buildings, objects and people.
