Recommended separation distances between
portable and mobile RF communications
equipment and the “Bluephase Meter”
The “Bluephase Meter” is intended for use in the electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the “Bluephase Meter” can help prevent
electromagnetic interference by maintaining a miminum distance
between portable and mobile RF communications equipment (trans-
mitters) and the “Bluephase Meter” as recommended below, accord-
ing to the maximum output power of the communication equipment.
For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (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 range applies.
NOTE 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
