Electromagnetic environment - guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the device,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.

800MHzto 2.7GHz：
d=2.3√p
Where, P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance.
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey, should be less than the
compliance level in each frequency range. Interference
may occur in the vicinity of equipment marked with the
following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.
