What is the effect of modulation duty cycle on RF exposure?
A lower duty cycle permits greater power levels to be transmitted✓Correct answer
A higher duty cycle permits greater power levels to be transmitted
Low duty cycle transmitters are exempt from RF exposure evaluation requirements
High duty cycle transmitters are exempt from RF exposure requirements
Explanation
Because the limits apply to time-averaged exposure, a mode that transmits only part of the time contributes proportionally less to the average. A lower duty cycle therefore allows a higher peak power for the same time-averaged exposure figure.
