For the maximum output power of transmitters not listed in the table
above, the recommended distance d in meters (m) can be determined us-
ing the formula in the corresponding column for the transmitter frequency.
Thereby, P is the maximum output power in watts (w) of the transmitter as
specified by the manufacturer.
Note 1:
For the frequencies 80 MHz and 800 MHz, the formula of the
higher frequency band is used.
Note 2:
These guidelines do not apply in all cases. Electromagnetic prop-
agation is adversely affected by absorption and reflection from buildings,
objects and human bodies.
