Abstract
This document provides a record of the minutes for the September 2006 meeting of the IEEE 802.19
Coexistence Technical Advisory Group, in Melbourne AU.
Notice: This document has been prepared to assist IEEE 802.19. It is offered as a basis for discussion and is not binding on the
contributing individual(s) or organization(s). The material in this document is subject to change in form and content after
further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.
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>.

The IEEE 802.19 Coexistence Technical Advisory Group (TAG) met in conjunction with the IEEE
802.11 Interim meeting in Melbourne, AU during the week of September 17-22, 2006.
Session: Tuesday AM2, 10:30AM to 12:30PM September 19, 2006 Chair: S. Shellhammer
Call to order – 10:35AM – S. Shellhammer
Approve the agenda: 19-06/0034r1 – approved 10:45AM by unanimous consent – S. Shellhammer
IEEE SA Patent Policy Statement was read from 19-06/0017r0 slide 2, 3 – 10:46 AM
Review Submissions on Coexistence Scenarios:
1. 802.11 TGn updated CA will be reviewed at the November meeting. – S. Shellhammer
2. IEEE P802.19-06/0036r0: Coexistence Scenario for Dynamic Frequency Selection (DFS),
Presented by S. Shellhammer – All present contributed to the discussion:
Comment on applicability of DFS for unlicensed scenarios – the document to be modified to allow
for the inclusion of unlicensed scenarios.
Comment the first comment necessitates the revision of the use of licensed and unlicensed
terminology though out the document. “Unlicensed” should be called “DFS enabled wireless
network”. Multiple alterative names were suggested for the “licensed wireless systems”: Primary or
Incumbent or frequency static or non-DFS enabled.
Comments (section 2) – Four cases should be considered, each having its own figure: radar (central
Tx/Rx), TV (central TX many Rx), wireless microphone (central Rx many Tx), and WLAN (every
unit is Tx and Rx)
Comments (section 3) – wording regarding time and names of time intervals need to be revised.
Comments (section 4) – Discussion on Metrics – PD is really the only metric that affects the
coexistence of the networks. PFA only effects the DFS system operation, not its interference
characteristics. For a given scenario we should probably set basic guideline assumptions for
calculating the noise figure.
A request to 802.18 should be made; to provide some guidance or guidance reference for sensing
levels, probability of detection requirements, and any other regulatory requirements deemed pertinent
for a DFS network operating in the currently considered licensed scenarios.
Any other business:
Update of 1900 group: S. Shellhammer – I haven’t had any recent interaction with them but they are
working on creating a draft. The SA ballot pool has been formed.
Motion to Adjourn 12:16PM– Joseph Levy, second Mark Austin, approved by unanimous consent.
