Description
本新型是關於一種行動通訊系統之轉發器,特別是關於一種具有多頻寬之轉發器。The present invention relates to a transponder for a mobile communication system, and more particularly to a transponder having multiple bandwidths.
在行動通訊系統中,轉發器(Repeater)是設置在基地台(Base Station)與行動終端設備之間。轉發器本質上是一種放大並轉遞一行動網路信號(又稱射頻信號)且無時間延遲的設備。在下行鏈路中,轉發器接收自基地台發射的信號,放大接收到的信號並發射放大後的信號,以致使行動終端設備得以接收之。在上行鏈路中,轉發器則以相反方式運作,以致使信號得以由行動終端設備經由轉發器而傳送給基地台。換言之,轉發器可用以延伸行動通訊網路之涵蓋範圍與容量。In a mobile communication system, a repeater is disposed between a base station and a mobile terminal device. A repeater is essentially a device that amplifies and forwards a mobile network signal (also known as a radio frequency signal) without time delay. In the downlink, the repeater receives the signal transmitted from the base station, amplifies the received signal and transmits the amplified signal to enable the mobile terminal device to receive it. In the uplink, the repeater operates in the opposite manner so that the signal is transmitted by the mobile terminal device to the base station via the repeater. In other words, the repeater can be used to extend the coverage and capacity of the mobile communication network.
習知之轉發器具有一固定之頻寬頻段,以適用於具有對應頻寬或頻率之行動通訊系統。然而,隨著智慧型行動終端設備的數量日漸普及,相對提高對於行動通訊網路之涵蓋範圍與容量的需求。因此,電信業者有時需更換提供之行動通訊服務的頻寬或頻率,藉以提升或維持通訊品質。此時,電信業者則必須隨著更改的頻寬或頻率而將行動通訊系統中的轉發器替換成具有對應頻寬頻段之轉發器。The conventional transponder has a fixed bandwidth band for use in a mobile communication system having a corresponding bandwidth or frequency. However, as the number of smart mobile terminal devices has become increasingly popular, the demand for mobile communication networks has increased. Therefore, telecommunications operators sometimes need to change the bandwidth or frequency of the mobile communication services provided to enhance or maintain communication quality. At this point, the carrier must replace the transponder in the mobile communication system with a transponder with a corresponding bandwidth band with the changed bandwidth or frequency.
一種具有多頻寬之轉發器包括一第一天線、一第二天線、以及一中繼模組。中繼模組耦接在第一天線與第二天線之間。中繼模組包括複數個濾波器以及一第一選擇單元。此些濾波器分別具有不同頻寬,並且耦接在第一天線與第二天線之間。第一選擇單元電性連接第一天線以及此些濾波器,並且用以選擇此些濾波器中之一以將選擇之濾波器與第一天線電性導通。A transponder having multiple bandwidths includes a first antenna, a second antenna, and a relay module. The relay module is coupled between the first antenna and the second antenna. The relay module includes a plurality of filters and a first selection unit. The filters have different bandwidths and are coupled between the first antenna and the second antenna. The first selection unit is electrically connected to the first antenna and the filters, and is configured to select one of the filters to electrically connect the selected filter to the first antenna.
綜上,根據本新型之具有多頻寬之轉發器可因應行動通訊系統所需之頻寬,選用對應頻寬之濾波器過濾行動網路信號中不必要信號,藉以放大行動網路信號,進而降地整體之時延並提高效用。In summary, according to the novel multi-bandwidth transponder, a filter corresponding to the bandwidth can be used to filter unnecessary signals in the mobile network signal according to the bandwidth required by the mobile communication system, thereby amplifying the mobile network signal, and then The overall delay of the land is reduced and the utility is improved.
