Abstract: The use of ultra wideband (UWB) radio technology in outdoor environments at longer ranges is gaining interest in a number of application areas. This effort presents the results of a UWB channel model study based on a data collection campaign in three outdoor channel environments: open campus, dense forest, and urban at distances up to 70 m. The aim is to present fundamental results in different channel conditions so as to lay the groundwork for developing effective outdoor UWB systems. Parameters extracted from the experimental data closely match parameters generated by the IEEE 802.15.4a UWB channel model, indicating that this model can be used to analyse properties of a wider range of outdoor channel environments than has been reported. The frequency dependent path loss and channel capacity, calculated for each channel, indicate that UWB is a feasible candidate for several longer range outdoor applications.
