Terminal device for the [FiReCOS] integrated firefighting and disaster radio systemVast amounts of information of all types are exchanged in the course of the efforts carried out by fire brigades as well as many other support teams in areas where natural disasters strike. Under such conditions, limitations naturally apply to the voice communications carried out using conventional radio technology.

In response, we have developed "FiReCOS" using PHS mobile communication technology and TCP/IP networking. The result is an efficient, congestion-resistant communication system for fire brigades. The system handles not only voice, but also digital data. It provides bone-conduction microphones, hands-free control, and other functions, and is designed for the easy use of fire brigades.

Another technology that holds great promise for effective communications between firefighters is "mobile ad-hoc networks (MANET)." This technology provides wireless communication by building a network configured solely of terminals in a certain area, such as a disaster site, and is believed to be suited to various organizations that split up and assemble as the situation demands, for example the fire brigade, police and military. We are using this MANET technology to develop a communication system between firefighting vehicles. This system will enable a single firefighting vehicle to be dispatched from anywhere in the country to a disaster site as part of an emergency firefighting support team in order to receive information and immediately share it simultaneously with all other vehicles involved in the effort. It is also hoped that the system will make it easier for information to be shared between local fire brigade headquarters at the disaster site and emergency firefighting support teams.
