Calculated distances and power compliance margins
The calculated minimum separation distances, recommended distances and resulting margins for each
frequency band and antenna combination is shown in Table 55 . 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.
PTP 450 equipment adhere 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 Table 55 :
Tx burst – maximum average transmit power in burst (Watt)
P – maximum average transmit power capability of the radio (Watt) (combined transmitters)
G – total transmit gain as a factor, converted from dB
S – power density (W/m
2
)
d – minimum distance from point source (meters)
R – recommended distances (meters)
C – compliance factor
