the mobile service is not
listed in the table, the
recommended separation
distance should be
calculated from the equation
appropriate for the
frequency of the transmitter.
Recommended separation
distance
D=(2) (√

where
P
is the maximum
output power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer and
d
is the
recommended separation
distance in meters (m).

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the 521200380100 S
