Portable and mobile RF communications
equipment should be used no closer to any part
of the Joerns WECC bed including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d=1,2√P
d=1,2√P
80 MHz to 800 MHz
d=2,3√P
800 MHz to 2,7 GHz
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).
Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
