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>.

History of Coexistence in IEEE 802
• IEEE 802.11 was introduced in 1997 for WLAN
operating in unlicensed frequency band
• IEEE 802.15 was formed in 1999 to develop standards
for WPAN, often operating in unlicensed bands
• IEEE 802.15.2 was formed in 2000 to address issue of
coexistence of WLAN and WPAN, primarily 802.11b
and 802.15.1 (i.e. Bluetooth)
• IEEE 802.19 Wireless Coexistence Technical Advisory
Group (TAG) was formed in 2001 to address wireless
coexistence across all of IEEE 802

IEEE 802 Policies and Procedures on
Wireless Coexistence
• Due to the increase in new projects for wireless
operating in unlicensed bands the IEEE 802 Executive
Committee decided in November 2004 to add a new
policy on wireless coexistence in the 802 policies and
procedures (P&P)
• The centerpiece of the new policy is the development of
a document referred to as a Coexistence Assurance
(CA) document
• The CA document is a study showing how well a
proposed wireless standard, planned for unlicensed
operation, coexists with current standards

IEEE 802 Policies and Procedures on
Wireless Coexistence
• The CA document is to developed by the time of the
first working group letter ballot and to be sent as a
companion document with the draft on each working
group and sponsor letter ballot.
• The CA document can of course be revised based on
new information or changes in the draft
• The WG and sponsor ballot pool, as experts in the field,
decide how to utilize this information in their vote
• The IEEE 802.19 Coexistence TAG also votes on WG
ballots and comments on the CA document

IEEE 802 Policies and Procedures on
Wireless Coexistence
• For more details you can see the 802 P&P on the 802
web site,
– http://grouper.ieee.org/groups/802/policies-and-procedures.pdf
• The 802.19 TAG has rules for how it votes on the CA
documents, which you can find on the 802.19 web site,

Functions of the IEEE 802.19 TAG
• The TAG is a service organization to all the wireless
working groups
• The TAG was fundamental in the formation of the 802
P&P on wireless coexistence
• The TAG has been working on the development of a
document called the Coexistence Assurance
Methodology document
– The plan is to use this as an internal IEEE 802 document initially
– It could be converted into a IEEE Guide after some time of internal
use
• The purpose of this document is to give guidance to the
working groups on how to develop a CA document

Functions of the IEEE 802.19 TAG
• The TAG holds joint meetings with the task groups of
the various working groups to discuss CA documents
and methodologies
– Met with 802.11n
– Met with 802.15.4b
– Meeting with 802.15.4a at September meeting
• The TAG has prepared presentation material to explain
more about the CA document requirements
– See presentation “What is a CA document” on the 802.19 web site

Functions of the IEEE 802.19 TAG
• The TAG also votes on all working group letter ballots
which include a CA document
• The TAG, as a group of technical experts, comment on
the CA document
• This process is just getting going and the process for
this voting was recently approved an included in the
802.19 P&P
– The TAG met in July with 802.15.4b to give technical advice
– The TAG will be meeting in September with 802.15.4a to review
preliminary analysis and give technical advice

Recent Activities of the TAG
• The development of the CA methodology document is
ongoing
– There will be a technical submission of a method of estimating
packet error rate (PER) at the September meeting
• There were several presentations in July summarizing
the coexistence related parameters of standards and
drafts
– IEEE 802.15.1 (Bluetooth)
– Draft 802.16 (WiMax)
– Cordless telephone technologies

Recent Activities of the TAG
• There will be several presentations in September
summarizing the coexistence related parameters of
several drafts
– IEEE 802.15.3a (UWB)
– Update on Cordless telephone presentation
• The TAG developed a list of which ongoing projects
require a CA document
– This list is available on the 802.19 web site
• The TAG continues to hold joint meetings with various
wireless working groups as appropriate to hear
preliminary CA analysis and give technical advice

and November
• The TAG meets at IEEE 802 joint wireless interims in
January, May and September
• Next few meetings

Liaison Next Steps
• The two groups can exchange liaison reports at each
meeting
• Hold a conference call after both the September
P1900.2 and 802.19 meeting to discuss more about what
the two groups are doing and possible areas of
collaboration
