Research About GSM Repeater Energy-Saving Technology Based On Time-slot Intelligent Shut

Repeater has been widely used in mobile communication system, due to its construction, low cost, simple installation, flexible networking, etc. As an auxiliary method of base station coverage, It's used to solve the problem of general base station coverage blind spots or weak zones and improve network quality. Repeater has been developed with the networks of mobile communication for more than ten years. Becoming increasingly popular at the same time, Repeater energy has become an important component of Mobile energy. Made great efforts in the communications industry, today's energy-saving work. To study the repeater energy will be very meaningful. This paper, repeater energy issues, presents a GSM time slot synchronization signal energy-saving design method, and describes the characteristics and implementation in detail.The first chapter of this paper firstly proposed to study the the necessity of repeater energy-saving, and Simply introduced the repeater status of energy-saving technology research and development trends, finally explained the purpose of this research topic, meaning, the main content and structure of paper. The second chapter of this paper made Simply description of the relevant theoretical knowledge, firstly introduced the GSM digital mobile communication system, as well as the basic characteristics of the composition, then introduced the GSM radio interface in the theory of some relevant knowledge, and finally introduced the GSM network directly put station, explana working principle, classification, applications.The third chapter described designing ideas and features of the turn-off based on the GSM slot intelligent energy-saving repeater and in accordance with system architecture described in detail in the GSM implementation of energy-saving repeater. The forth chapter introduced the core slot synchronization module of repeater, and details of hardware and software implementation. The fifth chapter, adoption of the experimental data and simulation results of the study, this paper verified technology of repeater energy-saving, showed off based on time slots of the GSM repeater intelligent energy-saving technologies is feasible. The last chapter of this research project is summarized and prospect.
