Domestic radio waves propagate management and control systems investigate the system status

Abstract

The International Telecommunications Union(: ITU) Radio Regulations(: RR) and in which is defined as the frequency of electromagnetic waves below 3000㎓ spread in space without artificial guidance, our country also follows the international definition. As radio waves are electromagnetic waves spreading in space without artificial induction means having a frequency within the range set by the ITU. Frequency distribution for dual-work is to inde 300㎓, among the divided frequency is our daily or less than 90% of the frequency band is in contact saenghwalyong 3㎓. Propagation, but can occur indefinitely without depleting that anyone can create only gatchumyeon transmission equipment, if the radio frequency to use at the same time and space, the soul is the interference occurs is not available radio resources. Due to the physical finiteness used in our country for the first time on such a propagation laws enacted in 1961 and to the state radio resource management, and rules to be used for propagation only if granted the rights.
