[技術發展-24]:現有物聯網通信技術特點

前言:
物聯網(Internet of Things,簡稱IoT)是指通過各種信息傳感器、射頻識別技術、全球定比特系統、紅外感應器、激光掃描器等各種裝置與技術,實時采集任何需要監控、 連接、互動的物體或過程,采集其聲、光、熱、電、力學、化學、生物、比特置等各種需要的信息,通過各類可能的網絡接入,實現物與物、物與人的泛在連接,實現對物品和過程的智能化感知、識別和管理。
物聯網是一個基於互聯網、傳統電信網等的信息承載體,它讓所有能够被獨立尋址的普通物理對象形成互聯互通的網絡。
物聯網( IoT ,Internet of things )即“萬物相連的互聯網”,是互聯網基礎上的延伸和擴展的網絡,將各種信息傳感設備與網絡結合起來而形成的一個巨大網絡,實現任何時間、任何地點,人、機、物的互聯互通。
物聯網是新一代信息技術的重要組成部分,IT行業又叫:泛互聯,意指物物相連,萬物萬聯。由此,“物聯網就是物物相連的互聯網”。這有兩層意思:第一,物聯網的核心和基礎仍然是互聯網,是在互聯網基礎上的延伸和擴展的網絡;第二,其用戶端延伸和擴展到了任何物品與物品之間,進行信息交換和通信。因此,物聯網的定義是通過射頻識別、紅外感應器、全球定比特系統、激光掃描器等信息傳感設備,按約定的協議,把任何物品與互聯網相連接,進行信息交換和通信,以實現對物品的智能化識別、定比特、跟踪、監控和管理的一種網絡。
關鍵技術包括:射頻識別技術、傳感網、M2M系統框架、雲計算
