研究方向

結合當前我國及福建省工業智能制造對“互聯網＋”的重大需求以及大力發展移動通信及互聯網融合的戰略目標以及申報人長期連續的研究內容，申報人在福建建設“新一代通信技術實驗室”（已完成），主要包括兩個研究方向：移動通信技術，信息網絡技術。重點服務智能制造、便捷交通系統，智慧能源，高效物流領域。

移動通信技術：國際上已經啟動對移動通信技術 5G 網絡資源的爭奪。我國重點規劃了北京、上海、廣州、寧波、蘇州為全國首批5G試驗網建設城市，計劃明年進行大規模測試組網，并于2019年啟動5G網絡實際建設，2020年有望實現5G網絡商用。發展5G的主要目的，就是讓無線傳輸速度更快、系統穩定度更高。還要能夠兼顧節能低功耗，以及更低的成本。

5G 的技術發展主要集中于四大方向，包括 Massive MIMO、新通信頻段（毫米波 mmWave 和光通信 Optical Communication）、新的調變技術（new modulation）和C-RAN（Cloud-RAN）。目前 Massive MIMO 是發展最快速的，因為 Massive MIMO主要是著重于基地臺端的技術，透過加大基地臺的天線設備，可以延續現階段 LTE 的功能，例如波束技術（Beam Forming）等。新通信頻段的啟用是因為 6GHz 以下的頻段太過于擁擠，透過新的頻段來提供更大頻寬，以進行更大數據的傳輸，毫米波和光通信也成為 5G 的市場兵家必爭之地。C-RAN 指的是云端基地臺與異質網路的整合。新的調變技術將會重新定義物理層的架構，再透過物理層之上的 C-RAN 規范，共同協調以使整個網路可以達到最佳化。

信息網絡技術：信息網絡技術的發展趨勢包括高速大容量，綜合集成以及網絡化。通信本身就是網絡，其廣度和深度在不斷發展，計算機也越來越網絡化。各個使用終端或使用者都被組織到統一的網絡中，形成“一個世界，一個網絡”。光纖傳輸和無線光傳輸的速率越來越高，波長從 1.3μm 發展到 1.55μm 并已大量采用。正交頻分復用 OFDM 技術已進入實用階段；光放大器代替光電轉換中繼器已經實用；相干光通信，光弧子通信已取得重大進展。這將使無中繼距離延長到幾百甚至幾千公里。隨著光纖技術以及無線光通信技術的逐漸成熟和應用，通信技術的帶寬正在變大，速率也在提升。
