Chapter 15 - Appendix - EMI Tables
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.
NOTE 3: 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 meters (m).
NOTE 4: Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less than the compliance level in each
frequency range.
b
NOTE 5: Interference may occur in the vicinity of equipment marked with the following
symbol:
a
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 NESS H200 Wireless System is used exceeds the applicable
RF compliance level above, the NESS H200 Wireless System should be observed to
verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the NESS H200 Wireless
System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
