Energy Saving in Wireless Access Networks
bookPart
The ICT sector is responsible for 2 to 3% of the global energy usage, which is roughly equal to the energy consumption of all air traffic. Because of the fast growth of ICT usage worldwide, the share of the ICT sector in the overall energy budget is growing. Therefore, the sector is undertaking a wide set of activities to improve its energy efficiency and carbon footprint. Also the wireless communications industry is actively working in this area. This chapter presents the various activities at research institutes, vendors, operators, standardization bodies, regulatory/governmental bodies, etc. in reducing the energy consumption and carbon footprint of the wireless industry. It also presents an example of reducing energy consumption in wireless access networks via dynamically switching on/off base stations (and cells) according to the current traffic demands. A quantitative analysis is presented to estimate the benefits of this approach. The analysis show that dynamic base station (cell) switching on/off has significant potential for energy saving.
