What we know, History
There is significant interference today
More coming
The problem is not conducive to automatic detection and mitigation within .11
Too many complexities
TGe doesn’t want the problem
There are more important issues
Most of the problem is with STA’s that have both .11 and BlueTooth in the same box.

What .11 Needs To Do
Provide the customer a means to manage the problem.
In simple terms that they can understand
Give equipment vendors a simple implementation
Provide .15 with a clear path to a workable solution

The Beacon Element
Simply indicates to the BSS when to keep quiet and for how long.
.15 will own the definition and specification
Becomes a .15 recommended practice that the vendors can implement if they want to accommodate this problem.
.11 need only specify the beacon element number reserved for this purpose.
May not need to be part of the .11 standard

The Motion
To direct the ANA (assigned numbers authority) to reserve a specific element ID for ownership and specification by the .15 working group.

6. What We Learned People just wanted to check this out before a vote

What We Learned
People just wanted to check this out before a vote
The original motion was a blank check… needed to be much more specific
TGh quiet period element is close enough
could use this with no action by .11
This could be used by manufactures to ‘solve’ the problem in ‘standard’ way.

7. September 2002
The New Motion
To direct the WG ANA (assigned numbers authority) to reserve a specific element ID for use by the TG2 working group under the rules established for the ANA.
This element be called the “ Co-existence Element”.
That the available document “01000D05P _Draft_Recommended_Practice” or subsequent revisions for review and letter ballot approval by both the and WGs.
