Hi,
I read many documents about QoS in WLAN but I don't understand few things. Maybe you'll help me :)

1. What's the difference between TC and TS?
TC is handling all types of traffic - Video, VoIP, BE...
So what is TS? Traffic in the same physical network?
2. What/who defines parameters in TSPEC?
3. About ToS marking.
ToS is marked in 3 layer (network), then (if my definition of TS is correct) in 2 layer ToS value will be changed if destination is in the same physical network right?

Thanks for any help :)
