摘要： An apparatus, method, and program capable of predicting an attenuation of electromagnetic waves in an upper airspace of a target area in consideration of the influence of long-term weather changes in future are provided. An apparatus for predicting an attenuation of electromagnetic waves between a radio apparatus located above a target area and a terrestrial surface is provided with a data acquisition section for acquiring past weather data in the target area, and an estimation section for estimating a weather corresponding to a future target year in the upper airspace of the target area based on the past weather data, and estimating an attenuation of electromagnetic waves based on an estimation result of the weather.

摘要： Provided is an information processing apparatus capable of determining an installation position of a radio-wave reflecting member without conducting an expensive field survey, so that radio waves with a predetermined power reach a target reception point located in an area out of line-of-sight, from a transmission point of radio-wave with a high frequency band. The information processing apparatus sets plural radio-wave propagation paths each with one reflection between a radio-wave transmission point in a target area and a target reception point located in an area out of line-of-sight against the radio-wave transmission point, based on map information of the target area, estimates reception characteristics at the target reception point for each of the plural radio-wave propagation paths, and calculates a total value of the reception characteristics by selecting the radio-wave propagation paths in descending order of reception characteristics at the target reception point, and determining an installation position of a radio-wave reflecting member based on a selection result of one or more radio-wave propagation paths selected by a time when the total value becomes higher than a predetermined target quality.
