How to save cell battery? Rebuilding radio mesh, using new antenna
How to save the battery of the cell? With an antenna for mobile phones that can follow each user with a dedicated single “beam” instead to use rainfall transmission of the radio signal. Reduce the power consumption of mobile networks per bit delivered is the Green Touch’s mission, a consortium of leading Information and Communications Technology (ICT) that want to save mobile batteries energy.
The new antenna presented in London this year could be reduced 100 times the energy consumption of mobile communications if it’s used in multiples of one hundred. In practice, replacing a single tower with hundreds of small transmitters, it would consume only 1% greater energy required from the antenna to get the same quality of service. But this is only the beginning.
The aim of the consortium, founded a year ago at the initiative of the legendary Bell Labs-Lucent Aleatel and now part of a forty public and private research centers, is to introduce by 2015 a series of “key elements” that can increase dramatically the efficiency of communications networks.
It’s an ambitious goal but not impossible to achieve. GreenTouch collects the best of global know-how, laboratories of private companies, even competitors – such as Huawei, Samsung. Swisscom and Telefonica and public research, such as that conducted by the University of Cambridge and the Tsinghua University.
All over the world the users of mobile phones are growing, data and video application’s explosion are generating an unprecedented wave of data traffic. The transport of large quantities of bits are now the rule even in mobile networks and then on the radio link with a data traffic doubles every year. In the near future additional scenarios are making big changes: Cloud computing with the distribution of users, applications, data, computing resources and storage. Without radical action mobile phone energy consumption will become a problem.
At present there is no real uniform radio mesh. This will waste a lot of energy, which would be saved if the networks were more homogeneous.
