Abstract: Disclosed herein are a wireless power transmission method and device in which rectifier performance of an Internet of things (IOT) sensor is taken into consideration. The method and device may be configured to identify rectifier performance of each of a plurality of IOT sensors, determine power to be transmitted to each of the IOT sensors based on a value for enabling power, output by the rectifier, to reach a predetermined maximum value based on the rectifier performance, and transmit the power to each of the IOT sensors in the form of electromagnetic waves.

Abstract: Various example embodiments relate to an Internet of things (IoT) gateway for controlling a data transmission terminal of an IoT terminal based on data prediction accuracy and an operating method thereof, in which the IoT gateway may be configured to receive first data from the IoT terminal based on a first transmission interval, recover second data within the first transmission interval based on the first data, predict third data based on the first data and the second data using a predetermined machine learning scheme, and control the first transmission interval by comparing the first data and the third data.
