Abstract: A ventilation device includes a main body case made of metal, a fan, a wireless communications unit, and a controller. Controller is configured to control fan in accordance with a signal received by the wireless communications unit. Main body case includes a suction section and an exhaust section. Suction section has a box shape, and includes a suction port. Suction section has a lower surface, an upper surface, and a front surface connecting a front edge of lower surface and a front edge of upper surface. Exhaust section is positioned on upper surface of suction section and includes exhaust port. Suction section includes a first opening and a second opening. First opening is in upper surface, and overlapped with at least part of wireless communications unit in upward-downward directions. Second opening is in front surface, and overlapped with at least part of wireless communications unit in forward-backward directions.

Abstract: When a main body case is viewed from below, an antenna is within a rectangular/square area defined by first to fourth points. An opening edge of a first opening includes: a first edge linearly along a first direction; and a second edge linearly along a second direction perpendicular to first direction, first point is defined as an intersection of a first straight line and a second straight line, first straight line includes first edge, and second straight line includes second edge. Second point is defined as a point apart from first point in first direction by a distance that is half prescribed wavelength. Third point is defined as a point apart from second point in second direction by a distance that is half prescribed wavelength. Fourth point is defined as a point apart from first point in second direction by a distance that is half prescribed wavelength.

Abstract: A wireless communication device has an aim of specifying, when transmitting data to another communication device, an antenna among antennas that can transmit data at a low transmission power. The wireless communication device switches between a first antenna and a second antenna upon transmission of a request signal to the other communication device, and increases or decreases transmission power for transmitting the request signal when switching between the first antenna and the second antenna.
Abstract translation: 无线通信装置的目的是在向另一通信装置发送数据时，指定能够以低发送功率发送数据的天线之中的天线。 无线通信设备在向其他通信设备发送请求信号时，在第一天线和第二天线之间进行切换，并且当在第一天线和第二天线之间切换时，增加或减少用于发送请求信号的发送功率。
