NOTE 1 - At 80 MHz and 800 MHz, the distance for the highest frequency range is to be applied.
NOTE 2 - These guidelines may not cover all situations. Electromagnetic radiation is affected by absorption and reflection by
structures, objects and people.
a)
The field intensities for fixed transmitters like base stations for radio telephones (cellular and cordless) and terrestrial mobile radios,
HAM radio devices, AM and FM radio transmitters and TV transmitters can not be theoretically foreseen accurately. In order to
assess an electromagnetic environment caused by fixed RF transmitters an electromagnetic study of the site must be considered.
If the field intensity measured in the location where the AirCube
conformity above the normal operation of the AirCube
performance is noted additional measures may required such as different orientation or positioning of the AirCube

The field intensity in 150 kHz to 80 MHz frequency range must be less than [V
