Evolution of European UWB Regulation

This document discusses the current European UWB regulation and its potential impact on wireless personal area networks (WPANs). It provides an overview of the ongoing debate and the limitations being considered. The document also highlights the measurements conducted by France Telecom R&D to assess the effectiveness of activity factor limitation as a mitigation technique. The results indicate the need for further consideration and potential revisions to the regulation.

  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: Evolution of European UWB reglementation Date Submitted: January 18, 2006 Source:Jean Schwoerer, Patricia Martigne] Voice: [+33 (0)4 76 76 44 83], Fax: [+33 (0)4 76 76 44 50] E-Mail: [jean.schwoerer@francetelecom.com;patricia.martigne@francetelecom.com] Abstract: [We present what is currently under discussion by the European regulator] Purpose: [To assist the group in evaluating what the European UWB reglementation can be] Notice: This document has been prepared to assist the IEEE P802.15.

  2. A short overview of the last changes in the European debate on UWB Jean Schwoerer France Telecom R&D

  3. The point on LDC limitations • Some measurements were done by FT to prove efficiency of activity factor limitation as a mitigation technique. • Results were presented at ECC TG3 in December • They shows that : • an unrestricted UWB device jam a weak Wimax link • Limitation of activity factor can overcome this issue

  4. The point on LDC limitations

  5. The point on LDC limitation What's currently under consideration is : • Ton max = 5 ms • Toff min = 250 µs • Toff mean = 38 ms with Σ Toff > 944 ms per second • ΣTon< 5% per second and 0.5% per hour But : • Other measurements with Wimax are on-going and could change thoses values (Next TG3 meeting : 14-16 February, and ECC meeting end of March) • 4G and IMT-Advanced also need to be considered.

  6. The point on LDC limitation Next TG3 meeting in February 2006 : • Resolution of the 67 comments from the Public consultation on the ECC Decision • Output from the February-TG3 to the March-ECC meeting = • a proposed revision of the Decision resolving the comments, • if TG3 discussions on LDC does not reach a consensus for integration of the LDC solution in the revised Decision, then some recommendations will be prepared for the ECC listing the pros and cons on LDC as a mitigation technique Next ECC meeting end of March : • Should finalize the Decision and decide whether the LDC solution shall be in it or not.
