Abstract: A device for controlling exposure of electromagnetic waves from a base station collects a power value received from at least one base station together with position information using a plurality of terminals in a controlled area; maps the received power value collected from the terminals on a plurality of subareas in the controlled area based on position information collected from the terminals; calculates a power density for respective frequency bandwidths in the respective subareas by using the received power value of the terminals provided in the respective subareas; and calculates a specific absorption rate of electromagnetic waves in a human body in the respective subareas by using a power density value for respective frequency bandwidths in the respective subareas.
