Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be used no
closer to any part of the Model Number or Type Number - by manufacturer,
including cables, than the recommended separation distance calculated
from 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 and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic
site survey, should be less than the compliance level in each frequency
range

NOTE I At 80 MHz end 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.
Field strengths from fixed transmitters, such as base stations for
radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured
field strength in the location in which the Model Number or Type
Number - by manufacturer is used exceeds the applicable RF
compliance level above, the Model Number or Type Number
- by manufacturer should be observed to verify normal
operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating
the Model Number or Type Number - by manufacturer.
Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than [Vi] V/m.
