Abstract: A wireless communication device (50) includes a housing (51) and a first board (52) placed inside the housing (51). On the first board (52) there is mounted a first communication circuit (61a) and a first antenna (61b) that perform wireless communication based on a first wireless communication system that uses a first frequency band and a second communication circuit (62a) and a second antenna (62b) that perform wireless communication based on a second wireless communication system that uses the first frequency band and is different from the first wireless communication system. The first antenna (61b) and the second antenna (62b) are respectively placed in a first region and a second region that are in a diagonal spatial relationship in plan view of the first board (52).

Abstract: Provide a sensor installation location determination support system and a sensor installation location determination support method that ensure accurate determination of sensor location information even in a case where a sensor to be installed is not equipped with GPS functionality. A sensor installation location determination support system includes a sensor detecting characteristic information of target object, a portable terminal communicatively coupled with the sensor for data communication, and a server collecting information.
