能源收集推動偏遠地區的移動電話技術

　　能源收集可以用來為電信網絡中的許多要素提供電力，節省大量的電力供應費用，并提供低維護監控。用風能或太陽能為移動電話基站供電，可以使電信網絡擴大到電網的范圍之外。當收獲時，內部熱能可以給系統周圍的傳感器提供能量。能源收集也被用來為手機手機充電，利用太陽能甚至是自行車的動能。

　　對于手機行業協會貿易團體估計，6億手機用戶生活在遠離電網的地區，主要是在兩個地區，南亞和撒哈拉以南的非洲地區，那里的農村人口比例仍然很高。在與親戚聯系、打電話給生病的人打電話以及許多其他服務，如手機銀行、天氣和農民價格信息等方面，缺乏上網電源是用戶生活中的一大障礙。這些服務被視為在減少貧困和縮小農村地區最嚴重的“數字鴻溝”方面至關重要，利用能源收集被視為提供數字信息基礎設施的一個關鍵途徑，以提供最低資本和運營成本。

　　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.
