Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < 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 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 TAG.

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

SCOPE
Coexistence refers to the co-location of IEEE P a devices with other, non-P a devices.
(definition from SCD doc rev16)
a includes :
UWB devices operating in the band 3,1-10,6GHz
CSS devices operating in the band 2,4GHz
UWB devices operating below 1GHz

WHO IS DOING WHAT?
Coexistence issues are coordinated by
Patricia Martigne, with liaison to 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

UWB in the 3,1-10,6GHz band
To address coexistence issues with the following existing IEEE standards :
• Bluetooth™ (IEEE ) – adjacent band
• P adjacent band
• IEEE b,g – adjacent band
• IEEE a – in-band
• IEEE – adjacent band
IEEE a – in-band

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

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 for discussion within a, scheduled on Tuesday evening.
