Abstract
Given the rapid development of science and technology, the community highly depends on the Internet network. Meanwhile, the information and communications technology have built a close and interrelated world. As a communication medium, the spectrum became a strategic scarce resource due to the different characteristics of application and the electromagnetic interference. In order to provide more high-speed and stable communication quality, the communication devices increasingly rely on the spectrum. Therefore, the concept of “spectrum sharing” has sprung up. Spectrum sharing is a more-efficient method to maximize the utilization efficiency of scarce resources. It consists of “Cognitive Radio,” “Spread Spectrum,” “Time Division Multiple Access,” “Frequency Division Multiple Access,” “Code Division Multiple Access,” and “Space Division Multiple Access”. However, the conflicts between the public interest and the individual rights make the regulations of spectrum sharing too complicated to be implemented. From the third generation to the fourth generation of mobile phone mobile communication technology standards, the application of dynamic spectrum sharing is booming. It is necessary that the regulatory regime for spectrum sharing is able to respond to the changes in technological development. In December 2015, the draft of Telecommunication Infrastructure and Resource Management Act was proposed. The present version of the Draft encourages spectrum sharing in order to enhance the efficiency of telecommunications; Moreover, to increase flexibility in the use of spectrum in the future. However, it is highly important that the regulatory regime for spectrum sharing are carefully designed and managed. This article focuses on not only the regulation of the use of the electromagnetic spectrum but also the regulatory regime for spectrum sharing. Last, this article recommends that the establishment of “spectrum sharing law” be of vital importance.
