Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.19. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the TAG of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <shellhammer@ieee.org> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.19 TAG. If you have questions, contact the IEEE Patent Committee Administrator at <patcom@ieee.org>. Patricia Martigne, France Telecom Patricia Martigne, France Telecom

September 2005 SCOPE The objective of this presentation is to initiate a discussion between 802.19 coexistence TAG and 802.15.4a TG with an objective of having a clear view of what is expected for the demonstration of 802.15.4a standard coexistence with the existing systems in the same band or in the adjacent bands. Patricia Martigne, France Telecom

September 2005 SCOPE Coexistence refers to the co-location of IEEE P802.15.4a devices with other, non-P802.15.4a devices. (definition from SCD doc.802-15-05-232rev16) 802.15.4a includes : UWB devices operating in the band 3,1-10,6GHz CSS devices operating in the band 2,4GHz UWB devices operating below 1GHz Patricia Martigne, France Telecom

WHO IS DOING WHAT? Coexistence issues are coordinated by September 2005 WHO IS DOING WHAT? Coexistence issues are coordinated by Patricia Martigne, with liaison to 802.19 coexistence TAG, mainly for UWB in the band 3,1-10,6GHz; For CSS (2,4GHz band) : John Lampe is the coordinator For UWB below 1GHz : Mark Jamtgaard Patricia Martigne, France Telecom

September 2005 802.15.4a CSS component Doc. 802-15-05-457rev1, presenting some simulation results of Coexistence between CSS and 802.11b, 802.15.1, 802.15.3, 802.15.4. Patricia Martigne, France Telecom

September 2005 UWB in the 3,1-10,6GHz band To address coexistence issues with the following existing IEEE standards : • Bluetooth™ (IEEE 802.15.1) – adjacent band • P802.15.3 - adjacent band • IEEE 802.11b,g – adjacent band • IEEE 802.11a – in-band • IEEE 802.15.4 – adjacent band IEEE 802.16a – in-band Patricia Martigne, France Telecom

To address coexistence issues with the following existing services : September 2005 UWB in 3,1-10,6GHz To address coexistence issues with the following existing services : • radars mobile phones others? (see FCC report, CEPT studies,…) Patricia Martigne, France Telecom

September 2005 UWB in 3,1-10,6GHz Coexistence between UWB and other systems in this band is a hot subject for UWB regulation in Europe! See doc. 802-15-05-535 for discussion within 802.15.4a, scheduled on Tuesday evening. Patricia Martigne, France Telecom
