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 group within .11 that is chartered to control the allocation of element ID’s to reserve a specific ID for ownership and specification by the .15 working group.
