Ultra-Wideband concepts applied to W band telecommunications

Ultra-WideBand (UWB) technology is very attractive since it offers a different approach to wireless communication compared to conventional narrow band systems. Global interest in this technology is high. This paper reports on the state of the art of UWB wireless technology and highlights key UWB features to apply UWB concepts in EHF frequencies, considering technological constraints and challenges on the realization of tx-rx architectures. In particular, the idea is to employ the UWB features exploiting the huge availability of bandwidth at high frequencies and overcoming the power emission limits, compliant with lower frequency communications (FCC standard) but not applied to W band. This could be a possible solution to increase transmission datarate and coverage ranges in order to support the new incoming communications needs. The analysis has been focused on W band UWB pulses generation and two different architectures have been analyzed and compared in terms of performance and complexity.
