A statistical UWB transmission networks in an indoor environment for PAN systems

The wideband indoor propagation channel measurements data at 3.1 GHz-10.6 GHz, a statistical ultra wideband (UWB) transmission networks are investigated and considered a promising technology for the future personal area network (PAN). In this paper, the UWB transmission channel characteristic are evaluated in the term of the frequency responses by using the vector network analyzer (VNA) in a convention room. The UWB signal with the specific center frequency and bandwidth is used for the transmitted signal. From the measured data, the major channel parameters such as path loss, mean excess delay and root means square (RMS) are shown. All of those results, a statistical model (e.g. power density function (PDF), and cumulative distribution function (CDF)) are provided and discussed.
