Description

可調整訊號頻段的分散式天線系統Distributed antenna system capable of adjusting signal frequency band

一種分散式天線系統，尤指一種可調整訊號頻段的分散式天線系統。A distributed antenna system, especially a distributed antenna system that can adjust the signal frequency band.

隨著現代科技的演進以及無線通訊技術的蓬勃發展，無線上網已成為各式行動裝置不可或缺的功能之一，而行動裝置的無線上網功能需要仰賴電信業者所設置的基地台(Base Station)及天線組成的網路，發射射頻訊號(Radio Frequency)以進行通訊。With the evolution of modern technology and the vigorous development of wireless communication technology, wireless Internet access has become one of the indispensable functions of various mobile devices, and the wireless Internet access function of mobile devices needs to rely on the base station (Base Station) set by the telecommunication company The network composed of antennas and antennas transmits radio frequency signals for communication.

一般射頻訊號在傳遞的過程中，容易受到地形及建築物的阻礙，雖然射頻訊號可穿透玻璃、木材或塑膠等材質，或是經由反射來達到訊號傳遞的效果，然而射頻訊號難以穿透鐵、鋼筋或水泥等建材，因此當行動裝置位於建築物較裏側的封閉空間，如地下室或密閉電梯時，基地台的射頻訊號受建築物的層層牆面及樓板所阻隔，無法傳輸至行動裝置，同樣的，行動裝置的射頻訊號亦無法傳輸至基地台，造成基地台與行動裝置間無法通訊，進而使得行動裝置容易發生訊號不良，甚至是無法執行無線上網的功能的情形。Generally, radio frequency signals are easily hindered by terrain and buildings during the transmission process. Although radio frequency signals can penetrate glass, wood, plastic and other materials, or achieve the effect of signal transmission through reflection, radio frequency signals are difficult to penetrate iron. Therefore, when the mobile device is located in a closed space on the inner side of a building, such as a basement or a closed elevator, the radio frequency signal of the base station is blocked by the walls and floors of the building and cannot be transmitted to the mobile device. Similarly, the radio frequency signal of the mobile device cannot be transmitted to the base station, resulting in the inability to communicate between the base station and the mobile device, which makes the mobile device prone to poor signal or even unable to perform the wireless Internet function.

為解決密閉空間內射頻訊號傳遞不佳的問題，並提高訊號的覆蓋率，現有一種分散式天線系統(Distributed Antenna System, DAS)，包含有一頭端單元(Head End Unit, HEU)及複數遠端天線單元(Remote Antenna Unit, RAU)，該頭端單元可設置於能夠穩定接收基地台所傳送的射頻訊號，受建築物結構阻擋較少的區域，例如建築物的頂端，通過無線通訊方式與外部的一基地台連接，接收該基地台所傳輸的射頻訊號，將射頻訊號轉換為一傳輸訊號以有線通訊方式向後端傳輸；該些遠端天線單元則分佈設置於建築物中通訊不良的區域，例如電梯內或地下室，而該些遠端天線單元透過有線通訊方式與該頭端單元連接，該些遠端天線單元接收該頭端單元傳輸的該傳輸訊號後，將該傳輸訊號轉換為原先該基地台所傳輸的射頻訊號，並通過各該些遠端天線單元的天線向外傳輸，供鄰近的行動裝置接收。In order to solve the problem of poor RF signal transmission in confined spaces and improve signal coverage, there is a distributed antenna system (Distributed Antenna System, DAS) that includes a head end unit (HEU) and multiple remotes Antenna Unit (Remote Antenna Unit, RAU), the head-end unit can be set up to stably receive the radio frequency signal transmitted by the base station, and is less blocked by the structure of the building, such as the top of the building, through wireless communication with external A base station connects, receives the radio frequency signal transmitted by the base station, converts the radio frequency signal into a transmission signal and transmits it to the back end through wired communication; these remote antenna units are distributed in the poor communication area of the building, such as elevators The remote antenna units are connected to the head-end unit through wired communication. After the remote antenna units receive the transmission signal transmitted by the head-end unit, the transmission signal is converted to the original base station location. The transmitted radio frequency signal is transmitted through the antennas of the remote antenna units to be received by neighboring mobile devices.

另一方面，目前主流的行動通訊技術為***行動通訊技術(the fourth mobile networks, 4G)，4G網路設備(例如現有的分散式天線系統)已廣泛使用，且行動通訊技術正逐漸朝向第五代行動通訊技術(the fifth mobile networks, 5G)發展，5G網路包含兩種頻段，分別是範圍為6HZ以下的Sub-6頻段，以及範圍為24GHZ-52GHZ之間的毫米波(mmWAVE)頻段，其中毫米波頻段的優點在於能支援較4G網路更大的頻寬且大容量的資料傳輸。On the other hand, the current mainstream mobile communication technology is the fourth mobile networks (4G). 4G network equipment (such as existing distributed antenna systems) has been widely used, and mobile communication technology is gradually moving towards The fifth generation of mobile communications technology (the fifth mobile networks, 5G) development, 5G networks include two frequency bands, namely the Sub-6 frequency band below 6HZ, and the millimeter wave (mmWAVE) ranging between 24GHZ-52GHZ Among them, the advantage of the millimeter wave frequency band is that it can support larger bandwidth and larger capacity data transmission than 4G networks.

然而，若將現有的分散式天線系統直接應用於5G網路其毫米波訊號的發射與接收，由於毫米波頻率較高、波長較短，使得毫米波的穿透力較弱，而當訊號的頻率越高，訊號的覆蓋距離也越小，且訊號於傳播路徑中的損耗也越大，造成現有的分散式天線自基地台或行動裝置所接收到的毫米波訊號強度可能過於微弱。However, if the existing distributed antenna system is directly applied to the transmission and reception of millimeter-wave signals in 5G networks, the higher millimeter-wave frequencies and shorter wavelengths make millimeter-wave penetration weaker. The higher the frequency, the smaller the coverage distance of the signal, and the greater the loss of the signal in the propagation path. As a result, the strength of the millimeter wave signal received by the existing distributed antenna from the base station or mobile device may be too weak.

此外，現有的分散式天線中各電路元件多用以處理***行動通訊技術(the fourth generation of mobile phone mobile communication technology standards, 4G)使用的中頻訊號，難以直接處理5G網路的毫米波頻段的訊號。In addition, the circuit components in the existing distributed antennas are mostly used to process the intermediate frequency signals used by the fourth generation of mobile phone mobile communication technology standards (4G), which makes it difficult to directly process the millimeter wave frequency band of the 5G network. Signal.

綜上所述，現有的分散式天線系統無法相容於5G網路其毫米波頻段，因此，為因應當前行動網路技術朝5G網路發展的趨勢，現有的分散式天線系統勢必需要進一步的改良。To sum up, the existing distributed antenna system is not compatible with the millimeter wave frequency band of 5G network. Therefore, in response to the current mobile network technology development trend toward 5G network, the existing distributed antenna system is bound to be further improved Improved.

有鑑於此，本新型的目的在於提供一種可調整訊號頻段的分散式天線系統，以期克服現有的分散式天線系統無法相容於5G網路其毫米波頻段的問題。In view of this, the purpose of the present invention is to provide a distributed antenna system with adjustable signal frequency band, so as to overcome the problem that the existing distributed antenna system cannot be compatible with the millimeter wave frequency band of the 5G network.
