能源收集推動(dòng)偏遠(yuǎn)地區(qū)的移動(dòng)電話技術(shù)

　　能源收集可以用來為電信網(wǎng)絡(luò)中的許多要素提供電力，節(jié)省大量的電力供應(yīng)費(fèi)用，并提供低維護(hù)監(jiān)控。用風(fēng)能或太陽能為移動(dòng)電話基站供電，可以使電信網(wǎng)絡(luò)擴(kuò)大到電網(wǎng)的范圍之外。當(dāng)收獲時(shí)，內(nèi)部熱能可以給系統(tǒng)周圍的傳感器提供能量。能源收集也被用來為手機(jī)手機(jī)充電，利用太陽能甚至是自行車的動(dòng)能。

　　對(duì)于手機(jī)行業(yè)協(xié)會(huì)貿(mào)易團(tuán)體估計(jì)，6億手機(jī)用戶生活在遠(yuǎn)離電網(wǎng)的地區(qū)，主要是在兩個(gè)地區(qū)，南亞和撒哈拉以南的非洲地區(qū)，那里的農(nóng)村人口比例仍然很高。在與親戚聯(lián)系、打電話給生病的人打電話以及許多其他服務(wù)，如手機(jī)銀行、天氣和農(nóng)民價(jià)格信息等方面，缺乏上網(wǎng)電源是用戶生活中的一大障礙。這些服務(wù)被視為在減少貧困和縮小農(nóng)村地區(qū)最嚴(yán)重的“數(shù)字鴻溝”方面至關(guān)重要，利用能源收集被視為提供數(shù)字信息基礎(chǔ)設(shè)施的一個(gè)關(guān)鍵途徑，以提供最低資本和運(yùn)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.
