Portable and mobile RF
communications equipment
should be used no closer to any
part of the device, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d =1.2 150kHz-80MHz
d =1.2 80MHz-800MHz
d =2.3 800MHz-2.5GHz
Where:
P is the maximum output power
rating of the transmitter in watts
(W) according to the transmitter
manufacturer;
D is the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey
a
should be less than the compliance
level in each frequency range
b
.
Interference may occur in the
vicinity of equipment marked with
the following symbol.
Note 1: At 80MHz and 800MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection structures, objects and people.
a
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 filed strength in the
location in which the device is used exceeds the applicable RF compliance level above, the device
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the device.
b
Over the frequency range 150 KHz to 80MHz, field strengths should be less than 10V/m.
