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, 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 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
Table 2
Recommended separation distances between portable and mobile RF
communications equipment and the Quell Device
The Quell Device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Quell Device
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
Quell Device as recommended below, according to the maximum output power of the
communications equipment.
