Introduction This Report considers interferences from devices using ultra-wideband (UWB) technology on radiocommunication services. As a main objective@ it evaluates UWB e.i.r.p. density required for the protection of radiocommunication services. The protection criteria for radiocommunication services were taken from liaison statements from the relevant Working Parties of the ITU-R@ input contributions to Radiocommunication Task Group (TG) 1/8@ and some from relevant ITU-R Recommendations and Reports. The technical studies consider the effect of a single device using UWB technology and/or the aggregate effect from multiple devices. For the aggregate case@ reference UWB deployment scenarios were defined. This Report also includes laboratory and field measurements on the impact of devices using UWB technology on radiocommunication services. As a result of the studies@ the maximum e.i.r.p. density for generic devices using UWB technology is provided; assuming a minimum separation distance from the device in the case of a single interferer or a relevant deployment scenario in the case of aggregate interference. Such limits are primarily based on analytical studies. Noting the regulatory status of the victim radiocommunication services and to ensure their full protection@ conservative reference analyses have been applied. The propagation models used in the studies are presented in a specific section. Mitigation techniques for devices using UWB technology are also provided.
