Annex 1: Transmission of RF
1. Though same frequency is allocated in some countries, national regulations may specify different
EIRP, spurious emission or other requirements.
2. ETS EN300 440 is the recommended harmonized standard for European Community, member
country may adopt their own national regulation. The AP96 series transceivers meet the requirement
of EN300 440
3. The AP96-US model is designed to meet the FCC standard part 15.245 and is aimed for use in the
America.
4. The regulations are subjected to change from time to time, please contact appropriate authorities for
full and up-to-dated information.

Annex 2: Doppler Equation
Where
F
d
= Doppler frequency
V = Velocity of the target
F
t
= Transmit frequency
c = Speed of light (3 X 10
8
m/sec)
 = The angle between the target moving direction and the axis of the module.
If a target is moving straight toward or away from AP96 (F
t
= 24.125 GHz). The formula is simplified
to:
F
d
= 44.7V (Velocity in km/hour) or 71.9V (V in mile per hour)
