Abstract: Provided is an aerial-staying type communication relay apparatus that can suppress fluctuations in a directivity pattern due to reflection at an antenna-mounting member to which a service link antenna is mounted, stably fix a footprint of a cell, and as a result, prevent deterioration of communication quality. The communication relay apparatus includes an antenna having plural antenna elements that form a cell for performing a radio communication of a service link to and from the terminal apparatus and an antenna-mounting member to which the antenna is mounted, and a layer of radio wave absorber or a layer of frequency-selective electromagnetic shielding member that selectively shields radio waves having a frequency of the service link, which is provided on an outer surface exposed to an outside of the antenna-mounting member. Phases and amplitudes of signals transmitted and received via each of the plural antenna elements of the antenna may be controlled.

Abstract: Provided is a wireless-power transfer apparatus capable of efficiently supplying a predetermined power for each of plural terminal apparatuses. A wireless-power transfer apparatus comprises a radio processing section for transmitting a signal for wireless power transfer to each of the plural terminal apparatuses via plural beams, by a beamforming for forming the plural beams against the plural terminal apparatuses simultaneously or at staggered times, an information acquisition section for acquiring terminal information including location information of a current location of a terminal apparatus for each of plural terminal apparatuses, and a control section for controlling the beamforming so that a signal for wireless power transfer is received at a predetermined reception power in each of plural terminal apparatuses, based on terminal information of each of plural terminal apparatuses.

Abstract: 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.
