Radio sets of the portable communications system, which are small size, light weight, and have long-lasting batteries, are also used in inter-prefectural emergency rescue activities in times of disasters. The portable communications system is mainly used in local police activities. The portable communications system is a wireless communication tool used for direct communications among portable wireless devices. This system is designed to cover the jurisdiction of each police station under the PPHs all over Japan.
The police-station-level communications system is a radio communications system used to communicate between police officers and police stations and between police officers.
Police-station-Level Communications System Using the radio set as a temporary relay station can expand a service area to perform radio communications in mountainous areas where radio waves do not normally reach. In addition, the system enables a radio set on a patrol car to conduct voice and data communications simultaneously.
The coverage, however, can be expanded to the whole nation if needed. This system is basically under the jurisdiction of each PPH. The mobile communications system is a radio communications system that enables the communications command center to give directions to police patrol cars, motorcycles, helicopters, boats or to police stations. The police have three radio communication systems: mobile communications system, police-station-level communications system, and portable communications system, as well as advanced infrastructures of police info-communications system.ĭigital encryption is employed in all of them to ensure high-level confidentiality as well as strong resistance to interference.
