Ultra Wide Band - A New Wireless Technology in Digital Home超寬帶-一種新的無線技術在數字家庭
There are several LAN (Local Area Network) technology that can link up communication devices in home networking such as wireless 802.11 a/b/g, Homeplug AV, MoCA (Multimedia Over Coaxial cable) and more.有幾個LAN （局域網）技術，能夠聯繫起來，通訊設備在家庭網絡，如無線支持802.11 a / b / g和的HomePlug AV ，閘道（多媒體同軸電纜）和更多。 Among these technologies, the most well known one would be 802.11 a/b/g wireless technology that doesn’t require cable and capable of handling high bandwidth.在這些技術，最有名的一個將支持802.11 a / b / g無線技術，並不需要電纜和能夠處理高帶寬。 Besides 802.11 wireless technology, some of us may not aware that there is another type of wireless technology known as UWB (Ultra Wide Band) which could support even higher throughput of up to 100 Mbps for wireless streaming in digital home.除了802.11無線技術，我們有些人可能不知道，還有另一種類型的無線技術被稱為超寬帶（超寬帶） ，其中可以支持更高的吞吐量高達100 Mbps的無線流媒體在數字化家庭。
As the name mentioned, Ultra Wide Band operates in a very wide spectral range from 3.1GHz up to 10.6 GHz.正如其名所述，超寬帶運營在一個非常廣泛的光譜範圍從3.1GHz上升到10.6 GHz 。 The bandwidth is about 80 times wider as compared to 802.11 which stay around 17 MHz.帶寬約80倍擴大為802.11相比，這保持在17兆赫。 In terms of power transmission, UWB has very low transmit power of about 0.1 mW, which is far lesser than 50mW required on 802.11 technologies.在電力傳輸，寬帶已經非常低的發射功率約為0.1毫瓦，這遠遠低於耗電50mW所需的802.11技術。
With such a low transmit power, UWB has advantage over 802.11 in extending battery life of communication devices, while it doesn’t compromise in the range that it can reach.有了這樣的低發射功率，超寬帶的優勢在802.11延長電池壽命的通信設備，同時它不妥協的範圍，它可以達到。 Surprisingly, it can cover up to10 meter radius as similar to 802.11 technology.令人驚訝的是，它最多可支付至10米為半徑類似的802.11技術。 This could be contributed by different modulation technique which is less susceptible to interference and multipath fading.這可能是由不同的調製技術是不容易受到干擾和多徑衰落。
More customer electronics products with integrated UWB feature can be expected to be on the shelves by mid of 2007.更多的客戶電子產品集成的UWB功能可以預期的貨架上中旬的2007年。
