Abstract
Recent analysis by manufacturers and network operators has shown that current wireless networks are not very energy efficient, particularly the base stations by which terminals access services from the network. The number of users and the use of telecommunication systems are increasing rapidly and this result in greater demands on energy usage. Based on the extensive Life-cycle assessment (LCA) conducted by various network operators, it is learned that energy consumption in the usage phase of its radio access networks is the most imminent factor relating to impact on the environment. The need for restructuring of existing network architecture, we need to control the systems in every base station. This paper discusses the current energy consumption scenarioin base station devices. It also describes innovative and promising method for enhancing the energy efficiency of the wireless networks and developing solutions that reduce operating costs and effects on the environment.
INTRODUCTION
Recent analysis by manufacturers and network operators has shown that current wireless networks are not very energy efficient, particularly the base stations by which terminals access services from the network. Green radio technology describes one of the most promising research directions in reducing the energy consumption as well as the carbon emissions of future base stations.
Given the worldwide growth in the number of mobile subscribers, the move to higher-data-rate mobile broadband, and the increasing contribution of information technology to the overall energy consumption of the world, there is a need on environmental grounds to reduce the energy requirements of radio access networks [4]. The Green Radio [1] program sets the aspiration of achieving a hundredfold reduction in power consumption over current designs for wireless communication networks. This challenge is rendered nontrivial by the requirement to achieve this reduction without significantly compromising the quality of service (QoS) experienced by the network’s users.
Basic Operation
Our objective is to reduce the energy consumption in base stations and reduce the amount of CO2 emission. We have to keep controlling system in every base station for switching purpose. To have complete control over base station we prefer to use PC. In this technology, the mobile- communication tower in an area is turned ON, based on the frequency of users present in that area. In general, within apre-defined control area, there will be multiple towers operating (of same network type). And each tower has pre- defined user-strength capacity, up to which it can operate. Thus, based on the user strength in a region, the number of towers in that particular region is turned ON and remaining
CONCLUSIONS
From the recent analysis, we see that increase in mobile users leads to increase in power consumption, which in turn leads to emission of more and more CO2. This leads to global warming as CO2 is considered to be one of the green house gases. In order to control this effect, the major area to be controlled is to reduce power consumption. This paper proposes a comprehensive approach towards an energy efficient operation [10] of next generation mobile communication. This can be reduced by taking various parameters into account such as the operation of Air Conditioner, cooling fan, light indicator and power amplifier. This project has aimed at reducing the power consumption by taking these parameters into account and the outcome has been positive.
