Policy and Technology of Dynamic Spectrum Access in Korea

In this paper, we introduce spectrum policies and dynamic spectrum access technologies in Korea. In the past, Korea spectrum management was the command and control with exclusive usage rights and small portions of spectrum commons bands. With the development of the radio technologies, recently, Korea government, MIC (Ministry of Information and Communication), has been adopting new spectrum policies based on dynamic spectrum access technology such as LBT (listen before talk) for RFID, UWB, and FACS (flexible access common spectrum) etc. MIC is also considering spectrum reallocation of digital dividend bands after DTV transition. New radio techniques such as cognitive radio and SDR will be applied to new services in this UHF band. MIC is trying to open the radio spectrum in an efficient way and adopt new technology into spectrum policy. Thus MIC is extending the open spectrum such as spectrum commons and spectrum liberalization bands.
