Electromagnetic environment –
guidance
Portable and mobile RF
communications equipment
should be used no closer to any
parts of the VRA201, 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
=
2 , 1
d = 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).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
