Recommended Separation Distances Between Portable and Mobile
RF Communications Equipment and Wi-Box™ AO Transmitter
Wi-Box™ AO transmitter is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of this device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and this device 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 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
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
RoHS Declaration
No toxic and hazardous substances according to RoHS contained.
