4G LTE高速移動通訊網路系統

技術簡介

 4G LTE高速移動通訊網路系統。
4G LTE高速移動通訊網路系統。

在高速移動環境下,無線電波易受干擾,影響接收訊號品質,工研院以自主開發的MIMO(Multi-Input Multi-Output)天線技術為基礎,結合WiFi及光載無線電(Radio Over Fiber,RoF)技術,成功克服因高速移動及行經空曠或遮蔽結構等所致之通訊障礙及相關技術挑戰。

特色與創新

方案藉由光載無線電(Radio over Fiber,RoF)技術延伸RF信號傳輸範圍,進行4G LTE高速移動通訊網路優化,有效提高信號涵蓋範圍(Cell Coverage),並大幅降低基地台(Base Station,BS)佈建成本。

應用與效益

相關技術成果、驗證測試與優化經驗可為國內外一般鐵路、捷運、國道客運等大眾運輸系統提供隧道及車廂通訊解決方案。
