style="text-indent:25px">網(wǎng)絡能耗問題就是5G普及路上的一個重大挑戰(zhàn)。從目前全球頻譜分布來看，要想獲得更多帶寬，5G頻段高頻化成為必然趨勢。高頻化所帶來的覆蓋區(qū)域變小，促使小區(qū)數(shù)量增加，而且站點頻段數(shù)量也會快速增加，站點頻段數(shù)從4頻到7頻甚至10頻以上。這些將導致5G時代全球站點數(shù)量倍增，站點能耗翻倍。由于能源緊缺和節(jié)能環(huán)保所帶來的雙重壓力，全球范圍內電費呈現(xiàn)逐年上漲趨勢，因而站點能耗的大幅上漲將進一步推高運營商的總體能源費用和運營成本。根據(jù)統(tǒng)計結果，能源費用目前普遍占全球運營商收入的1%~8%；在網(wǎng)絡能耗倍增、電價上漲的背景下，能源OPEX預計會出現(xiàn)三倍的增長。與此同時，全球超過70%的存量站點將面臨電源、配電、溫控和電池容量不足的挑戰(zhàn)，超過30%的站點需要進行市電改造，運營商面臨著極高的CAPEX壓力，降能耗、提盈利成為廣大運營商的重要關切點之一。汕頭高質量通信電源5G基站電源擴容通信電源市場收益。</p><div

style="text-indent:25px">5G未來已來，通信電源時至勢成。通信電源在5G時代受益的程度和持續(xù)時間遠高于4G時代,主要的驅動力來自于基站和數(shù)據(jù)中心。基站設備大功耗驅動通信電源需求.5G時代，基站設備（AAU 和BBU）功率大幅提升,是通信電源需求大爆發(fā)的主要驅動力之一。AAU方面，為彌補工作頻段上升導致的基站覆蓋性能下降，同時為配合大規(guī)模陣列天線Massive MIMO 技術的應用，5G 基站單扇區(qū)AAU的機頂輸出功率有望從4G的40-80w增加至200W甚至更高。而BBU方面，基帶處理能力大幅提升，電源功率的要求也將大幅提升。AAU 和BBU 的功率需求都要求電源側提供更高的輸入功率，進而導致電源容量的大幅增加。在現(xiàn)有供電系統(tǒng)的基礎上，基站電源存在極大的擴容和新建需求。</p><p style="text-indent:25px">通信電源是向通信設備提供交直流電的電源，是整個通信網(wǎng)的能量保證。為滿足未來5G容量和覆蓋需求，全球站點數(shù)量將急劇增加。而通信電源作為基站基礎的供能設施，是保證基站在室內/外，尤其是惡劣天氣、環(huán)境下正常運行的基礎設施。伴隨基站總數(shù)增長，國內通信電源市場也不斷擴大。隨著5G建設周期開啟，5G組網(wǎng)對于供電功率密度、供電效率及損耗率等提出更高的要求，將給行業(yè)帶來技術變革。5G基站能耗高、基站規(guī)模大，電源產(chǎn)品有望迎來“量價齊升”。5G基站功耗相較4G提升兩倍以上，同時5G站址密度遠超4G，電源產(chǎn)品單價有望“量價提升”。5G基站較高的功耗水平對通信電源系統(tǒng)提出了新的需求。通信電源一般以直流－48V或－24V供電。</p><div

1、極簡：5G電源需要遵循極簡的設計理念，5G電源創(chuàng)新解決方案實現(xiàn)少占空間、簡易安裝、快速部署和簡單運維。 2、智能：5G電源基于Bit管理Watt的理念，應用AI與Cloud技術實現(xiàn)電源與站點設備、電源與網(wǎng)絡設備多層次的智能協(xié)同，電源從“功能機”演進到“智能機”，支撐站點的CAPEX和OPEX大幅降低。同時站點運維也需要從傳統(tǒng)人工運維走向更有效的智能運維。 3、有效：區(qū)別于傳統(tǒng)基于單部件節(jié)能的設計，5G電源需要從供電、轉換、備電、配電、溫控和負載環(huán)節(jié)進行端到端的全鏈路有效設計。同時在供電環(huán)節(jié)，支持各類新能源接入，支撐綠色節(jié)能，實現(xiàn)0比特0瓦特的目標。5G通信電源用高頻變壓器產(chǎn)品。上?？诒猛ㄐ烹娫?/p><p
