Abstract :
To deal flexibly with interprefectural criminal cases, the National Police Agency (NPA) developed the mobile radio communication system, the WIDE (Wireless Integrated Digital Equipment) system. The WIDE system, which is usually used for telephone communications, provides a wholesale command function in the event of interprefectural criminal cases. Its wholesale command function makes it possible to build up an exclusive communication network transcending prefectural borders and covering all police vehicles concerned. The WIDE system is highly resistant to interception and is operated with a narrow occupied bandwidth of 8 kHz
