wer rating of the transmitter in watts

nufacturer and d is the recommended

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
surveyc, should be less than the com-
pliance level in each frequency ranged.

3 V/m
NOTE: At 80 MHz and 800 MHz, the higher frequency range applies
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people
NOTE: The ISM (industrial, scientific and medical) bands 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.
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are
intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently
brought into patient areas. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance
for transmitters in these frequency ranges. 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 device is used exceeds the applicable RF compliance level
above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the device. Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m. Recommended separation distances between portable and mobile RF communications equipment and this device.
This device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of this device can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and this device as recommended below, according to the maximum output
power of the communications equipment
