機載5G與Wi-Fi專用:低損耗、高穩定的客製化RF連接器

 

前言

隨著全球航空業的數位化發展,機載5G連網技術正快速演進,為商業與軍用飛機帶來更高速、低延遲的無線網路連接。根據市場研究,全球機載連接市場預計將在未來五年內保持穩定成長,主要驅動因素包括:乘客對高速Wi-Fi的需求增加、機上娛樂與商務應用升級、以及航空公司對機隊數據分析與遠端監控能力的強化。

特別是在5G毫米波技術(MM Wave)推動下,機載通訊系統不僅需要更高頻寬與更低延遲的數據傳輸能力,也面臨來自高空環境的嚴峻挑戰。從飛機外部的機載5G天線,到機艙內的Wi-Fi分發器,整體系統對RF連接技術的可靠性、低損耗與抗干擾能力提出了更高要求。因此,如何確保5G訊號在飛行環境下穩定傳輸,成為機載連網技術發展的關鍵課題。

 

 

客戶挑戰:機上Wi-Fi不穩,問題出在哪?

本案例客戶是一家航空通訊設備的開發商,經營機載5G天線與Wi-Fi分發器的設備與解決方案。不久前,他們從航空公司收到回饋:機上Wi-Fi發生連線不穩的情況,影響影音與商務使用,造成乘客旅途體驗不佳。

起初,客戶以為是軟體或主設備的問題,但經技術團隊分析後發現,問題並非出在設備本身,而是隱藏在一個容易被忽略的環節—機載5G天線系統內部的高頻RF連接器。

 

分析後發現的三大痛點:

  • 高頻訊號損耗過大:5G毫米波(24GHz以上)雖然提供極高速率,但訊號本身易衰減、穿透力低,原本使用的RF連接器在插入損耗方面表現不佳,在高空(30,000–40,000英尺)條件下進一步削弱訊號品質,導致Wi-Fi連線不穩。
  • 環境干擾嚴重:機載5G天線通常安裝在飛機外部(如機頂或機翼),需面對高空強風、濕度變化,以及雷達與導航系統帶來的電磁干擾(EMI)。尤其在雲層與降雨條件下,水氣會吸收毫米波訊號,進一步惡化連線品質。
  • 空間與重量受限:機艙Wi-Fi分發器安裝位置狹小,同時航空公司對設備重量高度敏感。原先採用的連接器體積偏大、屏蔽效能不足,不僅占空間,也加劇訊號干擾問題,限制了後續擴展設計。

 

客戶急需一款同時具備低損耗、高屏蔽、小型化與航空等級可靠性的RF連接器解決方案。

 

 

解決方案:讓5G訊號穩定穿越在3萬英尺的高空

針對客戶面臨的高頻訊號衰減、環境干擾與設備空間限制等挑戰,佳楠提供了一款專為機載5G天線系統與機艙Wi-Fi分發器設計的客製化RF連接器整合方案,特別針對航空設備的安裝環境與頻率要求量身打造:

 

1. 低損耗RF連接器設計,提升5G天線訊號傳輸效能

我們優化內部結構設計,並採用高精度導體與低損耗材料,將插入損耗降至 0.2 dB 以下(衰減降低 60%),顯著減少高頻訊號傳輸中的功率損耗。

針對5G毫米波(24 GHz 以上)頻段進行阻抗匹配設計,有效降低回波損耗,提升機載5G天線接收效率,使機艙內Wi-Fi訊號更穩定。

 

2. 高防護結構,穩定運作於雨霧與高EMI環境

連接器外殼採用高性能防水結構,達到 IP68 等級,即使在高空雨霧環境下也能穩定運作,避免水氣進入影響訊號品質。

連接器內部具備多層屏蔽技術,有效隔離來自機載雷達、導航設備等外部電磁干擾(EMI),確保5G訊號不受影響,提高天線系統的訊號接收能力。

 

3.小型化與輕量化,適合航空艙內安裝

針對機艙Wi-Fi分發器的安裝需求,佳楠採用高密度連接器設計,相較原本使用的連接器,體積縮小 30%、重量減輕 25%,適應艙壁內部狹小空間,並降低裝置總體重量。

這種小型化設計同時保留高頻傳輸能力,確保減少空間佔用的同時,不影響訊號穩定性。

 

4.搭配低損耗同軸電纜,提升整體系統傳輸效能

連接器搭配專門設計的低損耗同軸電纜,可進一步降低毫米波訊號在長距離傳輸中的衰減,確保5G天線到機艙Wi-Fi分發器的訊號完整性。

採用柔性電纜設計,提升佈線靈活性,更容易於航空設備內部安裝與維護。

 

 

創造價值:乘客體驗大不同!航空公司也有感

這次合作帶來的改變,不只是協助客戶技術升級,更是航空公司乘客體驗的實質轉變!

在導入佳楠客製化射頻連接器後,Wi-Fi訊號傳輸效率顯著提升,即使在飛行高度 3 萬英尺的高空環境中,乘客能輕鬆追劇、商務人士也能順暢開會,而不是盯著「重新連線中」的畫面苦笑。航空公司因上網問題收到的客訴大幅減少,取而代之的是對機上網路流暢體驗的好評。

對客戶來說,佳楠帶來的效益不只是一個連接器的升級,而是一套完整的系統可靠性解決方案。
