Suggested defence distance between the portable and mobile RF
telecommunication equipment and
HS112 C-1
HS112 C-1
was designed for being operated within the electromagnetic environment where
RF disturbances are under control. Buyer or user of
HS112 C-1
can avoid electromagnetic
disturbance between portable and mobile RF telecommunication systems (transmitters ) and
HS112 C-1
by defining the smallest possible defence distance depending on the maximum
output of the telecommunication transmitter which can be calculated as follows:

In case of transmitters with the highest output in the above table
d
defence distance (in meters) can be defined
with the equation depending on the frequency of the transmitter, where
P
stands for the maximum output (in
Watt) of the transmitter declared by its manufacturer.

Note: This guideline must not be used for each case. Electromagnetic transmission is influenced by
absorption and reflection caused by buildings, objects and people.
