Recommended separation distances between portable and mobile RF communications equipment and the
SIM™ system devices
The SIM™ system is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the SIM™ system can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the SIM™ devices as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power and not listed above, the recommended separation distance d in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter manufacturer. NOTE 1 At 80 MHz and
800 MHz, the separation distance for 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.
