Department of Electronics and Information Engineering, Huazhong University of Science and Technology, Wuhan 430074, China; 2. Changsha Telecommunications and Technology Vocational College, Changsha 410015, China) Abstract: Based on the characteristics and circumstance conditions of energy consumption of telecommunications network and according to the current situation of energy consumption of the communication equipment, power supply and base station, the energy-consumption distribution and energy-saving potential of the communications network were analyzed and the ways and measurements were put forward to save energy and reduce consumption. The fresh air energy-saving renovation plan in the communication equipment room and the comprehensive energy-saving solution for the mobile telecommunication base station were also proposed and designed. Qualitative comparative appraisal method was used to make scientific measurements and statistics of the practical energy-saving effect of the plan in the communications operation enterprises such as China Telecom and China Mobile. The experimental results show that if the communication operators can control and manage the energy consumption effectively, energy-saving techniques can be used and the energy-saving communications network can be designed which are based on informatization and precision management, and this is favorable for the energy saving, consumption reduction and sustainable development of the communications network and can guarantee the reliable and highly-effective operation of the communications network, so that capital and operational expenditure can be reduced. Key words: communications network; energy consumption; energy-saving 2008 05 10 2008 07 20 (06JJ2011) (07YBB313) (1965 ) 0731-6895101 E-mail: jqqhn@126.com
