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

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, in which P is
the maximum output power of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 and 800 MHz the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply to all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
