The recommended safety distance d in meters (m) can be determined
for transmitters, whose maximum power rating is not specified in the
above table, using the equation that belongs to the corresponding
column, wherein P is the maximum power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
Note 1
The higher frequency range applies at 80 MHz and 800 MHz.
Note 2
These guidelines may not apply in all cases. The propagation of
electromagnetic waves is influenced by their absorption and reflection
by buildings, objects and persons.
