11.3 SEPARATION DISTANCES RECOMMENDED BETWEEN PORTABLE AND MOBILE RF COM-
MUNICATIONS SYSTEMS AND THE REFERENCE SYSTEM, " XENON LIGHT SOURCE ".
The reference system, " Xenon light source ", is designed to be used within an electromagnetic environment in
which radiated RF interference is controlled. The user of the reference system, " Xenon light source ", can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communication systems (transmitters) and the reference system," Xenon light source ", such as recommended
below, as a function of the maximum output power of the communications system.

For transmitters of which the maximum output power is not listed above, the recommended separation
distance d in meters (m) can be established by using the equation applicable for the transmitter frequency, in
which P is the transmitter's maximum output power in Watts (W) assigned by the transmitter's manufacturer.
NOTE 1 : At 80 MHz and 800 MHz, the separation distance stated for the higher frequency range should be
applied.
NOTE 2 : These recommendations may not apply in all situations. The propagation of electromagnetic waves
is modified by absorption and reflection due to structures, objects and people.
