簡介：

通訊及網絡實驗室主要研究方向為移動通訊技術和互聯網技術，前期曾建有第三代（3G）移動通訊科研實驗室和IPv6科研實驗室。現在主要研究領域為新一代通訊及智能計算技術，包括認知無線電、物聯網、雲計制、區塊鏈、軟件定義網路（SDN）、網絡入侵檢測及防禦、無線人工智慧的研究等。

主要設備：

實驗室建立了一個獨立科研網絡，采用1Gbps主幹網絡和具有獨立50Mbps光纖連接的Internet出口。實驗室自主建立了一套私有雲系統及SDN系統。雲系統連接在思科(Cisco)新一代數據中心專用的N9K高速交換機系統，能爲雲系統的每個獨立端口提供10Gbps的連接帶寛及高達40Gbps的交換機之間的主幹連接帶寛。
