    全球物聯網商用情況及三大燃氣表新萬博體育

    文字:[大][中][小]

      物聯網為提高人民生活質量、促進各行各業發展、促進經濟增長開辟了廣闊前景。

      隨著全球主流運營商的選擇,NB-IoT將在公共網絡中成為主導,eMTC緊隨其后,逐漸完善支持中速率物聯網的網絡覆蓋。 NB-IoT與eMTC正在加速構建蜂窩物聯網(C-IoT)的接入基礎設施。截止2018年11月,全球已商用的移動物聯網網絡達到66張,均為各國和地區主流運營商。其中eMTC(LTE-M)商用網絡為13張,NB-IoT商用網絡有53張。作為擁有全球最廣泛網絡覆蓋的運營商,沃達豐目前已在10個國家商用開通了NB-IoT網絡,并宣布將NB-IoT排在資本支出計劃的高優先級,在2019年年底之前,會把位于歐洲的NB-IoT基站數量增加一倍。

      目前,NB-IoT通信模組廠商數量已突破20家,伴隨廠家的增多,市場競爭進一步加劇,促使模組價格逐步拉低。另外,運營商對于模組的大額補貼使模組價格進一步接近規模商用邊界,目前NB-IoT模組價格處于20-35元不等,其中單模模組集中于20-30元。

      根據GSMA報告:“NB-IoT和LTE-M是5G系列的一部分”。5G技術將人與人之間的通信擴展到萬物連接。萬物互聯的目標,要求5G技術有較強的兼容性,以滿足不同應用情景的需求。NB-IoT適應于低功耗大連接的場景,是5G物聯網家族一部分,也是5G發展的“橋頭堡”。

      LoRa雖然得到Orange、SK電訊、KPN電信集團、塔塔通信、康卡斯特等主流運營商的支持并嘗試全國性的網絡,但更多是一些城市級專用網絡或小范圍專用網絡,成為私有網絡部署的典型。LoRa得到快速落地,是目前私有物聯網網絡的主導形式。LoRaWAN全球超過5千萬傳感器;100個國家部署LoRaWAN 運營商;到2018年底全球超過 90 個運營商。

      Sigfox由于其超窄帶的特點,應用場景受限且得不到主流運營商的支持,也無法在公共網絡領域形成主導。

      作為物聯網領域的新技術以及未來的發展方向,憑借其廣覆蓋、大連接、低功效、高安全等技術特點,為智慧燃氣建設帶來了更優的技術解決方案以及更豐富的應用場景。燃氣是目前NB-IoT應用中少數可達百萬級的應用之一。新萬博體育

      金卡智能公告指出,預計2018年實現收入18.56-21.94億元,同比增長10%-30%。實現歸母凈利潤4.53-5.67億元,同比增長30%-60%。而業績增長主要原因之一就是:NB-IoT物聯網技術應用深度及廣度不斷提升。

      2018年金卡NB-IoT智能終端及智慧能源云平臺同時獲得華為技術Validated認證,從終端到云端的整體解決方案得到進一步認可。產品戰略縱深持續推進,同時NB-IoT覆蓋廣度進一步提升,驅動物聯網智能燃氣表及系統軟件銷售持續擴大。

      1月8日在投資者互動平臺上透露,公司2018年度物聯網NB-IoT智能燃氣表訂單穩定,銷售態勢良好。

      2019年1月,杭州先鋒中標南京港華NB-IoT智能燃氣表采購項目,截至2018年10月先鋒電子目前NB-IoT產品合作客戶已經達到118家,用量突破12萬臺。

      2019年1月烏克蘭第三大移動運營商lifecell已開始為PJSC“Kyivgas”燃氣公司智能設備部署窄帶物聯網,該網絡將遠程記錄燃氣表讀數、監控天然氣供應的穩定性并及時防止泄露。該項目已在愛立信、Odine Solutions和申明網絡的支持下實施。lifecell在1800 MHz頻段完成了NB-IoT網絡部署的第一階段,這項技術將允許成千上萬的設備連接到基站。PJSC“Kyivgas”燃氣公司開發了專用的燃氣消耗表傳感器,可通過lifecell NB-IoT網絡將自動讀取數據并傳輸到PJSC“Kyivgas”燃氣公司服務器。

      眾所周知,在國際產業競爭中,我國的最大優勢往往來自于規模優勢。可以預測,從長遠來看,NB-IoT在燃氣行業的應用必將提升中國整個物聯網產業在國際上的競爭力。

      了解更多關于物聯網與表計的信息,電水氣熱,公用和非公用領域,LoRa、NB-IoT、Sigfox……,主流和非主流物聯網技術,傳統表計行業和物聯網技術融合催生的新產業,存量和增量疊加的市場空間,如何匹配最終用戶的痛點和剛需?《2018年中國物聯網表計用戶體驗報告》給你答案。
