采用无线通信技术UWB(超宽带)的消费电子产品终于上市,这种技术使用的频带宽度达到了数GHz。在2006年的圣诞节期间,有若干款产品被投入日本和美国的市场。UWB技术的特点之一是能够提供高达几百Mbps的通信速率,跟现行的WLAN相比,要高出1个数量级以上。另一方面,因为这种技术所使用的频带很宽,人们担心会对各种无线通信系统造成不良影响,所以,各国政府对于这种技术在消费电子产品中的应用都采取了谨慎的态度。 Finally, the consumer electronics products using UWB (Ultra-Wideband), a wireless communications technology that uses bandwidths up to several GHz. During Christmas 2006, several products were introduced into Japan and the United States. One of the features of UWB technology is the ability to provide communication rates of up to hundreds of Mbps, which is more than an order of magnitude higher than the current WLANs. On the other hand, governments are cautious about the application of this technology in consumer electronics due to the wide frequency band used by this technology and the fear of adverse effects on various wireless communication systems.
