Recommended Separation Distances Between Portable
and Mobile RF Communications Equipment and the
Receiver
The receiver is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the receiver can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the receiver
as recommended in the next table, according to the maximum output power of
the communications equipment. Portable and mobile RF equipment includes: baby
monitors, Bluetooth wireless headsets, wireless routers, microwave ovens, laptops
with internal Wi-Fi adapters, GSM cell phones, RFID scanners and hand-held security
metal detector often used by security screeners.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance (d) in feet 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.
