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.

Abstract: A method of providing an amount of exposure to electromagnetic waves, and a user terminal are provided. The method may include receiving a signal of each of a plurality of wireless services, extracting a measured electric field and a reference level of electric field strength from a signal associated with each of the plurality of wireless services, and determining an exposure index of each of the plurality of wireless services, based on the measured electric field and the reference level of electric field strength, the exposure index being measured outside a body of a user.
