Abstract Share this page

Communication is a process of transferring information from a source to a destination in an attempt to create shared understanding. Before the wireless age started 15-20 years ago, people mainly relied on the wired networks for communications. Nowadays, wireless communications has become a necessity for many people. Every year, for the cellular networks alone, there are over 120,000 new base stations deployed around the world [1]. Each base station consumes an average power of 1 KW and uses a total of 8,766 KW-hours each year. This amount of power is equivalent to the energy consumption of two typical 3-bedroom family houses in the UK, or one average household in the USA [2]. In some countries, the costs of power consumptions in the base stations of cellular networks account for 50% of the overall expenses of the service providers. It is also startling to learn that over 1% of the entire world’s carbon footprint is due to telecommunications. The implication of carbon footprint and energy cost is making green communications imperative and urging much research work on energy saving and harvesting. The OMICS Group special features such as Digital Book (paperless) and Open Access just well fit green communications
