If the rated maximum output power of the transmitter is not included in the values given
above, can be estimated by using the corresponding column isolation distance
equation. In the equation P is the nominal maximum output power of transmitter
manufacturers are given, measured in watts.
If the system image severely disturbed affect diagnosis, it is necessary to set the
device away from the noise source or install the external RF transmission power noise
filter the noise reduced to an acceptable level.
Be careful 1 :
In 80MHz-800MHz, using a higher frequency formula
Be careful 2:
These guidelines do not apply in all cases. The material
structure, objects and people can absorb and reflect electromagnetic waves, thus
affecting the electromagnetic propagation.
