5g Radio Access Networks: Centralized Ran, Cloud-Ran and Virtualization of Small Cells (5G無線接取網路：集中式RAN、雲端RAN與小型基地台虛擬化)

C-RAN和虛擬化小型蜂窩技術帶來了幾個重大的研究挑戰。這些挑戰包括動態資源分配、基頻池中的自我配置、無線單元和基頻單元之間的高延遲數據傳輸、數據傳遞成本、網絡中的大量數據、軟件網絡方面、潛在的節能、安全問題、用戶個人數據在遠程地點的隱私、虛擬化環境的限制等等。本書深入探討了下一代RAN架構，並在不同層面上對文獻中提出的SDN、C-RAN和小型蜂窩解決方案的共存進行了調查。
