Wireless technologies work out of sight to allow people to carry out rich communications with peace of mind. For example, wireless technologies are used in most communication devices around us, including mobile phones, TV sets, radios, and GPS devices. Further, satellite communications and mobile phones are the most essential as means of communication in places such as mountainous areas and islands, where optical cables are difficult to be laid, and in times of disaster.

The Wireless Networks Research Center of the National Institute of Information and Communications Technology (NICT) conducts research and development of wireless communication and wireless network technology to allow people and things to flexibly and reliably communicate under any kinds of situations through the effective use of frequency and energy resources.
