This Paper deals with basic introduction to UWB Technology and why it is so attractive. The UWB mask for different countries are also discussed along with the application of the technology.
Ultra wideband technology has great potentials to enhance the wireless technologies as compared to conventional narrow band technology. Because of this fact researchers are attracted towards this band. A report in February 2002 by Federal Communication Commission was issued which was a major breakthrough for UWB Technology. FCC had approved the band of 3.1 GHz to 10.6 GHz for unlicensed use for indoor and outdoor applications in the USA. Our paper gives brief introduction in section 1 followed by reasons for using this technology in section 2. Section 3 describes the spectral mask implemented by various countries and section 4 describes the application of this technology. Section 5 discusses the types of ultra wideband communication systems and Section 6 concludes the paper.
