Note1 : At 80MHz and 800MHz, the higher frequency range applies.
Note2 : These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects, and people.
1. 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 LEDEX
RF compliance level above, the LEDEX
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the LEDEX
2. Over the frequency range 150kHz to 80MHz, field strengths should be less than
3V/m.
