Evolution of European Regulatory on UWB

This document discusses the evolution of European regulatory on Ultra-Wideband (UWB) technology, including the latest updates and challenges. It also mentions the ongoing work on Dynamic Aperture Allocation (DAA) and Low Duty Cycle (LDC) techniques for UWB systems.

  2. Evolution of the European regulatory on UWB Jean Schwoerer, France Telecom R&D

  3. DAA • Work on DAA started at the last ECC TG3 • Protection level is now -85 dBm/MHz • Must protect Wimax but also other systems (Radar, other BFWA) • Some doubts of the feasibility of such a system Jean Schwoerer, France Telecom R&D

  4. LDC • New contribution of France with measurement result focused on applications (Vidéo, FTP, VoIP) • Used parameters : • Ton max = 5 ms • Toff mean > 38 ms with Σ Toff > 944 ms per second • Toff min = 0.25 ms • Σ Ton< 5% per second and 0.5% per hour • PSD max -41.3 dBm/MHz Jean Schwoerer, France Telecom R&D

  5. LDC Jean Schwoerer, France Telecom R&D

  6. LDC • Result : • Strong opposition from Siemens and Wimax forum (same representative) • The Wimax community consider this non-protective enough and ask for more severe Ton/Toff to get 1dB degradation at 1m (almost done) or at 36cm (more challenging) • ECC TG3 consider LDC as an efficient mitigation technique but that need further study Jean Schwoerer, France Telecom R&D

  7. LDC • Nexts steps : • See if separation distance is 36cm or 1m (end of march) • Make more generic measurements (different repartition of Ton/Toff) • Determine new parameter for 1dB degradation at 1m (or 36 cm) • Contact exist with Wimax forum to agree on the measurement setup Jean Schwoerer, France Telecom R&D

  8. To be solved by ECC end of march • Project to authorize UWB between 4.2 and 4.8 GHz until 2010 without DAA/LDC • No agreement on that topic • Power level in some band : • 2.7 - 3.1 GHz : -85 dBm/MHz is asked by some administrations • 3.1 - 3.8 GHz : -85 dBm/MHz is asked by some administrations if no mitigation is used. • 8.5 – 9 GHz : -65 dBm/MHz is asked by some administrations Jean Schwoerer, France Telecom R&D
