Recommended Separation Distances
The table below provides the recommended separation distances (in meters)
between portable and mobile RF communication equipment and the MAC 5500.
The MAC 5500 is intended for use in the electromagnetic environment on which
radiated RF disturbances are controlled. The customer or the user of the MAC 5500
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
MAC 5500 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 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
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people
