Background
Existing DCF solutions restrict user parameters selections so that reasonable behavior results in most situations
Existing EDCF solutions allow that EDCF parameters may be set to any value for a station – even if not reasonable
Need to protect the user from himself (and each other

Background (2)
One malicious user could bring down entire network by choosing unreasonable setting
Should encourage station designs to not permit users to adjust EDCF parameters
Force to receive setting from QAP
Further safeguards may be desired in AP
Infers that should not be able to use EDCF in IBSS or BSS since need QAP

Market Impact
Reliable use of medium is key to success
While non complaint use of license free bands is allowed, should not be encouraged
Eg. Use of EDCF in BSS
Vendors need to police themselves to ensure malicious use of their designs is not allowed
Otherwise if malicious use of medium becomes common will limit growth of for many applications
