本發明關於一種無線基地台陣列天線的自我檢測方法，特別是指一種於無線基地台上設置參考天線，測試無線基地台天線的收發功能有無異常之檢測方法。The invention relates to a self-detection method for a wireless base station array antenna, in particular to a detection method for setting a reference antenna on a wireless base station to test whether the transceiver function of the wireless base station antenna is abnormal.
目前行動通訊系統的目標為利用有限頻率資源和時間進行通訊，為了達到此目標，多重存取(BDMA)技術是必需的。波束多重存取是使用相位陣列天線實現分空多重存取 (Space Division Access)，藉著使用波束成形技術及使用多個波束來達到多重存取，利用陣列天線來達到增加天線分集增益、空間多工和清除干擾的功用。其產生的場型可為多波束(Grid of Fixed Beam)或適應性波束(Adaptive Beam)，這些波束的形成與陣列天線中的天線單元、天線間距及陣列型態相關。The current goal of mobile communication systems is to communicate using limited frequency resources and time. To achieve this goal, multiple access (BDMA) technology is required. Beam multiple access is achieved by using a phased array antenna to achieve space division access. By using beamforming technology and using multiple beams to achieve multiple access, array antennas are used to increase antenna diversity gain and space. Work and remove the effects of interference. The generated field type may be a Grid of Fixed Beam or an Adaptive Beam, and the formation of these beams is related to antenna elements, antenna spacing, and array patterns in the array antenna.
相位陣列天線大致可分為適應型波束系統(Adaptive Beams Systems)與切換式波束系統 (Switched Beams Systems)，其原理為給予天線陣列單元不同之相位及功率大小分佈，使陣列發射/接收波束方向與波束寬度改變。在此概念下，行動裝置和無線基地台的狀態都在視線上（Line of Sight），彼此可確切知道對方位置。若未在視線上，就須靠相位陣列天線並搭配使用智慧天線來進行波束掃瞄切換，透過波束掃瞄，從無線基地台和行動裝置來取得信號抵達角度訊息去支援無線電定位。Phase array antennas can be roughly classified into Adaptive Beams Systems and Switched Beams Systems. The principle is to give different phase and power size distributions to the antenna array elements, so that the array transmit/receive beam directions are The beam width changes. Under this concept, the state of the mobile device and the wireless base station are both on the line of Sight, and each other can know exactly where the other party is. If it is not in line of sight, it is necessary to use a phased array antenna and use a smart antenna for beam scanning switching. Through beam scanning, the signal arrival angle information is obtained from the wireless base station and the mobile device to support radio positioning.
一般來說，為了傳輸信號時的順暢度，無線基地台多是架設在高處，例如建築物的頂樓或是電塔上。然而，當無線基地台的陣列天線傳輸出現異常時，由於檢測儀器體積龐大且造價昂貴，將檢測儀器搬運至現場就地測量有實行上的難度，因此維修人員必須將無線基地台的傳輸設備拆卸搬運至實驗室進行檢測維修，不僅曠日費時，維修成本也直線上升。In general, in order to smooth the signal transmission, the wireless base station is mostly placed at a high place, such as the top floor of a building or an electric tower. However, when the transmission of the array antenna of the wireless base station is abnormal, since the detection instrument is bulky and expensive, it is practically difficult to carry the inspection instrument to the site for on-site measurement, so the maintenance personnel must disassemble the transmission equipment of the wireless base station. Carrying it to the laboratory for inspection and maintenance is not only time-consuming, but also the maintenance cost goes up.
