5G | 第五代行動通訊技術

  • 第五代行動通訊技術是什麼?
    5G 是「第五代行動通訊技術」的縮寫,為下一代行動網路的名稱。

    1G網路帶給我們第一支手機,2G網路開始能發簡訊,3G網路啟用行動互聯網。目前正在使用的 4G,自 2009 年以來開始部署全球。4G LTE(長期演進的結果)是 4G 的最新版本,允許下載速率高達約 200Mbps。然而,4G 網路的功能已無法滿足現今使用者,他們希望的手機和其他設備能容納更多的數據和有更快的速度。因此,研發出具有更快速和傳輸量的新型網路是我們努力的方向。

    「5G」技術僅是一個對下一代行動網路的指標,如延遲、網路連接密度、和數據傳輸速率。一旦達到這些標準,5G 應該能夠處理比當今網路多 1000 倍的流量,並且比 4G LTE 快 10 倍。

    無線電頻譜頻段(介於30 – 300GHz之間)將開放使用,因5G網路技術由無線電頻率「毫米波」組成, 但毫米波容易被建築物阻擋,又容易被大氣中的氣體,植物和雨水吸收,毫米波對傳輸可達範圍有所限制, 需要安裝成千上萬個小型基地台(蜂巢式網路)進行傳輸。另外,為降低5G的延遲,多接取邊緣運算技術(MEC)也隨之興起。

  • 為何需要?
    提到 "5G",多數人所知的eMBB(增強型行動寬頻服務),它將實現在手機上閃電般快速上傳/下载的速度。

    5G的另外一項特性是 URLLC(超可靠低延遲通信) - 用於須低延遲及高可靠性的應用場景。例如:自動駕駛、VR、工廠自動化等領域,技術人員不再需要透過無線電雙面聯繫,能直接使用VR技術來清楚地看到和理解緊急情況。

    另一個重要的特性為mMTC(巨量多機器型態通訊) - 支援大量的終端IoT裝置連結,主要應用於智慧城市、工廠自動化、智慧家庭。

  • 技嘉的特色
    為了實現 5G 技術,營運商若是要將整個前端與後端網路設備進行升級,可能要價不斐。 例如:就僅有目前前端 RAN(無線電接入網)建設來說是不夠的,5G部署所需的基地台數量是現今的4倍,建設成本將比4G高出10~20倍。

    為提供上述提決方案,GIGABYTE 與 ITRI 合作開發 iMEC:智慧移動邊緣運算平台,可大幅減少移動來回的頻寬,並提供超低延遲邊緣雲端平台,結合 GIGABYTE 伺服器和+ 雲端虛擬化技術可以取代昂貴的軟硬體,降低後端成本,運營商能夠快速部署,並兼顧成本效益地實現下一代移動網路。

    Over 100,000 Pokémon Fanatics Gather to Catch ‘Em All - See How GIGABYTE’s High Density Servers Help Maintain Law & Order
    Large scale events can lead to a sudden surge in crowds, creating cellular network congestion. Even if the user capacity of a cell tower user is upgraded, the network operator is still unable to cope with an abrupt increase in demand. In 2019 Industrial Technology Research Institute (ITRI) therefore designed and built a “Private Cell Mobile Command Vehicle”, which can deploy a pre-5G private cellular network to avoid the problem of commercial network traffic jams. The vehicle provides the New Taipei City Police Department with smooth, uninterrupted cellular network service, allowing the police staff to remotely monitor real time footage of large scale events and deploy police resources where needed, increasing the efficiency of providing event security and safety. GIGABYTE’s H-Series High Density Servers are also helping to support ITRI’s “Private Cell Mobile Command Vehicle” by reducing the complexity of back-end infrastructure – each server combines computing, storage and networking into a single system, allowing for resources to be centralized and shared across different applications. The servers also optimize the use of time and manpower by combining and centralizing applications to simplify management procedures.
    What is Edge Computing? Definition and Cases Explained.
    Edge Computing: computing performed physically or logically as close as possible to where data is created and commands are executed. Offering excellent advantages in latency reduction for applications relying on real-time decision making.
