Radio waves are used in a wide variety of situations, for TVs, cellular telephones, and other functions that are familiar to us, and for highly public purposes, such as in the radio telecommunication systems used by the police, the fire department, ambulances, airlines, ships, and disaster prevention programs.
There are many cases, however, where radio is used illegally, when radio terminals are used without licenses, or when they are modified illegally so as to disrupt the operation of other radio stations.
In order to secure the fair use of radio, the Spectrum User Fee System was introduced on April 1, 1993. This is to secure a radio user environment without mixed or obstructive signals, and also to digitalize licensing procedures and promote a more efficient way of radio use, in order to cope with the sudden increase in radio stations.
Spectrum user fees are used for the following expenses, as stipulated by the Radio Law.
