　　能源收集推动偏远地区的移动电话技术

　　能源收集可以用来为电信网络中的许多要素提供电力，节省大量的电力供应费用，并提供低维护监控。用风能或太阳能为移动电话基站供电，可以使电信网络扩大到电网的范围之外。当收获时，内部热能可以给系统周围的传感器提供能量。能源收集也被用来为手机手机充电，利用太阳能甚至是自行车的动能。

　　对于手机行业协会贸易团体估计，6亿手机用户生活在远离电网的地区，主要是在两个地区，南亚和撒哈拉以南的非洲地区，那里的农村人口比例仍然很高。在与亲戚联系、打电话给生病的人打电话以及许多其他服务，如手机银行、天气和农民价格信息等方面，缺乏上网电源是用户生活中的一大障碍。这些服务被视为在减少贫困和缩小农村地区最严重的“数字鸿沟”方面至关重要，利用能源收集被视为提供数字信息基础设施的一个关键途径，以提供最低资本和运营成本。

　　To create momentum and foster innovation around solar phones and off-grid handset chargers， the GSMA is currently working on a project with operators to address these off-grid charging issues. Amongst other objectives， this project aims to build a knowledge-sharing platform accessible to all operators and provide them with advisory services on how to tackle off-grid charging issues.

　　Kinetic charging is widely used in developing countries as a cheap and easy solution for charging mobile phones. In East Africa， where the number of bicycles is high， it is easy to set up a dynamo system to charge a small battery. On average， 10 minutes of cycling at roughly 10 km/h would provide enough power to produce around 28 minutes of talk time for a low-end phone. The bikes are usually connected to a larger battery （car battery or smaller）， so that power can subsequently be distributed to several phones at the same time.
