Recommended separation distance: where
P
is
the output power rating of the transmitter in
watts (W) according to the transmitter manu
-
facturer and
d
is the recommended separation
distance in metres (m).
b
Field strengths from
fixed RF transmitters, as determined by an elec
-
tromagnetic site survey
c
, should be less than the
compliance level in each frequency range.
d
Inter-
ference may occur in the vicinity of equipment
marked with the following symbol.
Note 1
At 80 MHz and 500 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 struc
-
tures, objects, and people.
a
The ISM bands (for industrial, scientific and medical application) between 150 kHz
and 80 MHz are 6.765 MHz to 6.795 MHz, 13.553 MHz to 13.567 MHz, 26.957
MHz to 27.283 MHz and 40.66 MHz to 40.70 MHz.
b
The compliance level in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range of 80 MHz to 2.5 GHz is intended to reduce the prob
-
ability that portable communications equipment could cause interference if it is
inadvertently brought into patient areas.
This is why an additional factor of 10/3 is used in order to calculate the recom-
mended distance for transmitters in these frequency ranges.
c
Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radios, 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 electro
-
magnetic site survey should be considered. If the measured field strength in the
location in which the equipment is used exceeds the applicable RF compliance
level above, the equipment should be observed to verify normal operation. If ab-
normal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the system.
