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>.

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.

SCOPE
• Coexistence refers to the co-location of
IEEE P802.15.4a devices with other, nonP802.15.4a 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

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

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

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. 802-15-05-535 for discussion within
802.15.4a, scheduled on Tuesday evening.
