Abstract: In view of the big boost of the global evolvement of UWB technology, the motivation of this paper is to investigate its possible interference impacts on some of the existing radio systems commonly deployed for government applications. It is sensible to expect all the existing services should survive when there is a new comer to share the precious resources of spectrum. Unfortunately this study together with many others show that it may not be the case. Typical application scenarios are modeled for interference analysis resembling realistic deployments. Two government radio systems are selected for study. One is a terrestrial fixed microwave link which is rather robust in an environment with UWB interference because of its highly directional antenna. The second system is a digital broadband radio working in the public safety band which suffers significantly from shortened useable range or degraded data throughout.
