UWB communications transmit in a way that doesn’t interfere largely with other more traditional narrowband and continuous carrier wave uses in the same frequency band. UWB is the leading technology for freeing people from wires and enabling wireless connection of multiple devices for transmission of audio,video and other high bandwidth data. INTRODUCTION CONCEPT : A significant difference between traditional radio transmissions and UWB transmission is that traditional systems transmit information by varying the power level,frequency and phase of a sinusoidal wave. UWB transmissions transmit information by generating radio energy at specific time instants and occupying large bandwidth and enabling a pulse position modulation. One of the valuable aspects of UWB radio technology is the ability for a UWB radio system to determine “time of flight” of the direct path of the radio transmission between transmitter and receiver at various frequencies. CONCEPT REGULATION : Ultra wideband may be used to refer to any radio technology having bandwidth lesser of 500 MHz. The FCC power spectral density emission limit for UWB emitters operating in the UWB band is -41.3dBm/MHz. There has been much concern over the interference of narrowband signals and UWB signals that share the same spectrum;traditionally the only radio technology that operated using pulses was spark-gap transmitters,which were banned due to excessive interference. REGULATION THEORATICAL DISCUSSION : THEORATICAL DISCUSSION Channel capacity is the theoretical maximum possible number of bits per second of information that can be conveyed through one or more links in an area. Channel capacity increases linearly by increasing bandwidth of the channel to the maximum value available,or equivalently in a fixed channel bandwidth by increasing the signal power exponentially. Multipath is an enemy of narrow band radio. It equally affect UWB transmissions, but according to the Shannon-Hartley theorem and with reference to the variety of the geometrics applying to various frequencies. Multiple antenna scheme such as MIMO have been used to increase the system throughput and the reception reliability. CLASSIFICATION : Despite the single named used for the UWB transmissions, there are two very different technologies being developed : 1) Carrier free direct sequence ultra wideband technology : this transmits a series of impulses. In view of the very short duration of the pulses, the spectrum of signal occupies a very wide bandwidth. 2) Multi-band OFDM ultra wideband technology : this uses a multiband orthogonal frequency division multiplex signal that is effectively a 500MHz wide OFDM signal. This is hopped in frequency to occupy a sufficiently high bandwidth. CLASSIFICATION WIRELESS USB : WIRELESS USB ADVANTAGES : Transmit information over a large bandwidth (>500MHz). Doesn’t interfere largely with other wave used in the same frequency. They can be used at very low energy levels. Low power spectral density. ADVANTAGES DISADVANTAGE : This may effect the stability of such existing(traditional) system. High cost Rise of noise level by a number of UWB transmitters puts a burden on existing system. DISADVANTAGE APPLICATIONS : Target sensor data collection. Precision locating and tracking. Wireless printing of digital pictures from camera without pc. APPLICATIONS CONCLUSION : This is being recognized as a technology with a huge capability and as such it is being adopted in many new areas. Many silicon manufacturers have already developed solutions which are being demonstrated, and more are being developed. According to this new technology shows a significant degree of promise and should be a major force in the wireless industry in years to come.
