Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be used no closer to and part of the (ME EQUIPMENT or ME SYSTEM), including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = [ 3,5 / V1 ] √P
d = [ 3,5 / E1 ] √P 80 MHz to 800 MHz
d = [ 7 / E1 ] √P 800 MHz to 2.5 GHz
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 metres (m).
Field strengths frrom fixed RF transmitters, as
the compliance level in each frequency range. B
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.
aField 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 electrom agnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the (ME EQUIPMENT or ME SYSTEM) is used exceeds the applicable RF compliance level above, the (ME EQUIPMENT or ME SYSTEM) should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
bOver the frequency range 150 kHz to 80 MHz, field strengths should be lsee than [V1] V/m.
