Table 6 Recommended separation distances between portable and mobile
RF communications equipment and the ME EQUIPMENT or ME SYSTEM –
for ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances
between portable and mobile RF communications equipment and the device.
The device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the device
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmittters) and the
device as recommended below, according to the maximum output power of the
communications equipment.
Rated maximum output
power of transmitter
(W)
Separation distance according to frequency of transmitter (m)
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (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 80MHz and 800MHz, 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.
