Communications

A communication device is a device that enables a telephone call using wireless communication. In order to communicate, devices that want to communicate must be paired. There are differences in the number of devices that can be used at the same time depending on the device, ranging from one-to-one communication to one that allows simultaneous communication with four or more devices. It is mainly used for conversational purposes, but some products can receive radio with an FM tuner and shoot movies. Some operations can be performed directly from the buttons on the main unit, and others can be operated remotely with a smartphone.
