Calculat ed d ist ances and p o w er co m p liance m arg ins
The following tables show calculated minimum separation distances, recommended distances and
resulting margins for each frequency band and antenna combination for the USA and Canada. These are
conservative distances that include compliance margins. At these and greater separation distances, the
power density from the RF field is below generally accepted limits for the general population.
450 Platform Family ODU adheres to all applicable EIRP limits for transmit power when operating in MIMO
mode. Separation distances and compliance margins include compensation for both transmitters.
Explanation of terms used in the following tables:
l
P burst – maximum average transmit power during transmit burst (Watt)
l
P – maximum average transmit power of the radio (Watt)
l
G – total transmit gain as a factor, converted from dB
l
S – power density (Watt/m2)
l
d – minimum safe separation distance from point source (meters)
