Which among the following is an advantage of spectrum sensing with radio environment map? Correct Answer Reduction in observation time

The radio environment map holds both present and past radio environment information. Spectrum sensing with prior knowledge is more effective than continuous scanning of the entire radio spectrum. Consequently, the observation time, cost, and energy consumption of radio can be reduced.
