Table 18. Recommended Separation Distance between Portable and Mobile RF Communications
PLEASE NOTE: The USB Interface is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or user of the USB Interface can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the USB Interface as recommended below, according to the maximum output power of the

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 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
