Recommended Separation Distances between Portable and

Mobile RF Communications Equipment and the BIS VISTA

Monitor

The BIS VISTA Monitoring System is intended for use in the electromagnetic environment

in which radiated RF disturbances are controlled. The customer or user of the BIS VISTA

system can help prevent electromagnetic interference by maintaining a minimum distance

between portable and mobile RF communications equipment (transmitters) and the BIS

VISTA system 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 determined 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 ranges

applies.

NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is

affected by absorption and reflection from structures, objects, and people.
