吉林移動室內覆蓋供電保障系統的建設及效果分析

摘要：：隨著移動通訊業務的快速發展，對寫字樓、酒店、商場、超市等人口稠密場進行信號覆蓋或加強（覆熱、覆忙）的室內微峰窩基站逐漸成為移動運營商保障的一個重點。近年來由于國內電力緊張，城市用電量大，供電線路老舊，經常出現事故性或讓電等電力中斷，導致微蜂窩斷站，因此迫切需要對室內覆蓋微蜂窩系統建設供電保障設施。本文著重介紹了室內覆蓋系統的供電現狀、各場景的基站應用的布置、斷電及分布等情況，探討了在室內覆蓋系統應用壁掛式UPS、一體化戶外直流電源等交直流供電的不同解決方案，對使用效果進行了理論計算，并通過各方案在吉林移動各地市的應用做出了實際使用效果分析。 敘詞：室內覆蓋、供電保障、壁掛式、UPS、戶外直流電源 Abstract：Along with the fast development of mobile telecommunication networks, it has gradually been significant to provide the operating guarantee for the indoor micro cellular base station systems that covering or enhancing signal for buildings, restaurants, shopping malls, supermarkets (hot or busy point). Recently years because the energy supply shortage, the power demand raise continuously, the power supply circuitry was dated, the micro cellular base station systems were often out of service by the power supply accident or inadequate supply. It is very import to provide the special power supply equipment for the indoor micro cellular base station systems.
