Ultra Wide and Communication: Practical Applications and Future Aspects

Wireless communication technology has given us convenient ways to transfer information from one point to other anywhere in the world. The recent popularity of wireless networks results in many additional requirements of the system, especially the need of high data rates, demand for high quality multimedia services and the requirement of the greater bandwidth. The Ultra Wideband (UWB) radio communication is providing a new direction to utilize the radio spectrum for the broader short-range radio communications. Ultra-wideband (UWB) technology is a revolutionary wireless technology used to transmit large amounts of digital data over short distances (up to 230 feet) over a very wide bandwidth (from 1 gigahertz [GHz] up to 10 GHz ) and at very low power levels (less than0.5 milli watt). Unlike typical radio frequency broadcasts that use continuous sine waves to transmit data, UWB uses precisely positioned pulses at specific time intervals to transmit the signals across a wide spectrum. Ultra-Wideband (UWB) wireless is a rapidly growing technology that promises to revolutionize low power, short-range wireless applications. UWB has quickly emerged as the leading technology for applications like wireless Universal Serial Bus (USB) and short-range ground penetrating radars. UWB radios differ from conventional narrow-band radios, with a variety of specialized test demands. This paper discusses the concept behind ultra wide band communication technology, application areas, technological challenges ,spectrum operating zones and future aspects of the technology. The majority of the discussion focuses on the state of the art of ultra wide band technology as it is today i.e. practical applications in present era and in the nearer future.
