Abstract

The power consumption of wireless access networks has become a major economic and environmental issue, providing dedicated power supply for cell sites is one of the major issues for mobile communication system. In particular, base stations cause more than 80% of the operator’s power consumption, which makes the design of base station a key element for determining both the environmental impact of wireless networking and the operational expenditure. Utilizing renewable energy sources such as the solar, wind and bio – fuels as an alternative energy would be the ultimate solution to the mobile telecommunication industry. This paper presents an overview of integrating solar energy as alternative renewable energy to power cell sites in mobile cellular systems. The power consumption for three and six sector site have been evaluated. Optimization strategies to reduce the power consumption deployed and hence, solar power solution for both the optimized and non optimized site has been design. Analysis of results shows that, the average power consumption for the site increase with increase in the number of transceivers per sector. It is note-worthy that an increase of 768W per transceiver was recorded for the three sector site. It was also found that, the number of required solar panels and batteries for both optimized and non optimized sites increase with increase in number of TRX per sector.
