Abstract: A device includes: N communication modules, a selector that selects one communication module, an obtainer that obtains a reception strength of a signal, a generator that generates an image that includes 2N display regions associated with the N communication modules in order of communication speed from slower to faster per two display regions counted from a reference position along one direction, and a display. The generator generates, as the image, an image displaying (i) a graphic of a first type in, among the two display regions associated with the one communication module, more display regions counted from proximity to the reference position along the one direction, with an increase in the reception strength of the one communication module, and (ii) the graphic of the first type in each of two display regions associated with a communication module that communicates at a slower speed than the one communication module.

Abstract: An appliance management system includes an appliance, a server that manages the appliance and that can be connected to the appliance via a plurality of different networks, and a selection device provided in a communication channel that connects the server and each of one or more networks of the plurality of networks. The selection device selects, from the plurality of networks, one network to be used for communication between the appliance and the server based on a comparison of communication-related properties of the plurality of networks and causes the appliance and the server to communicate via the selected one network.

Abstract: A control method for controlling a device that includes a plurality of communication modules including a long-distance communication module that is a communication module for long-distance wireless communication and a short-distance communication module that is a communication module for short-distance wireless communication, the device being capable of being connected through each of the plurality of communication modules to a server that manages the device, the control method includes: receiving information necessary to the short-distance wireless communication by the short-distance communication module, when the long-distance communication module and the short-distance communication module are not operating; determining whether the information satisfies a condition indicating that the information received in the receiving is sufficient for a first connection to the server using the short-distance communication module; and causing the long-distance communication module to start operating, when it is determined that the information does not satisfy the condition.

Abstract: A wireless communication device of the present disclosure, to which an electric power measurement value is input that is measured in an electric power measurer to which a power supply side power line and a load side power line are connected, includes a first antenna element that transmits and receives radio waves and a wireless circuit connected to the first antenna element. The first antenna element has a longitudinal side perpendicular to a line along which the power supply side power line and the load side power line extend.

Abstract: A wireless communication device includes: flow-rate measuring unit connected to fluid pipe; and first antenna element that transmits and receives a radio wave. First antenna element has a longer side orthogonal to an axis of fluid pipe. According to this configuration, a direction of a plane of polarization of a radio wave radiated from first antenna element is orthogonal to fluid pipe. Thus, the radio wave is not reflected by fluid pipe but propagates in a direction toward fluid pipe, namely, in a rear surface direction of a meter including the wireless communication device.
