PolicyandTechnologyofDynamicinKorea
文章讲述了现在韩国的频谱政策和动态频谱接入技术。过去韩国的频谱管理政策需要特权,并且只有一小部分频谱可以公用。随着无线技术的发展,现在,韩国政府,使用了机遇动态频谱接入的新型频谱策略,例如LBT技术用于REID,UWB和FACS等。MIC还考虑如何在DTV过渡完成后,重新分配频谱。新型的无线电技术如认知无线电和SDR将在UHF边带中应用新的服务。MIC试图用一用有效地方式开放频谱并接受新技术用于频谱策略中。(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 com-
munication), 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. )
