Recommended separation distances between portable and mobile
radiocommunication equipment for I-PRESS which are not supporting vital
functions
I-PRESS is intended to operate in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the operator of I-PRESS
can help prevent electromagnetic interference by ensuring a minimum distance
between mobile and portable RF communications devices (transmitters) and I-
PRESS, as recommended below, according to the maximum output power of the
radio communication devices.

For transmitters rated at a maximum output power not listed above, the recommended
𝑑𝑑
separation distance in metres (m) can be calculated using the equation applicable to the
frequency of the transmitter, where
𝑃𝑃
is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Notes
(1)
At 80MHz and 800MHz; the higher frequency range applies.
(2)
At 80MHz and 800MHz; the higher frequency range applies. Electromagnetic
propagation is affected by the absorption and reflection from structures, objects and
people.
