nbase-t and wave 2

[cisco8887]

hi All,

if you use a wave 2 ap which is rated at 5gbps with cat6e and connected to a 10gb port, can that port auto negotiate to 5gb or the switch has to be multi gigabyte for this to happen ?

in another word, are there any APs that support wave2 and have a 10gb lan card which can connect to a 10gb 6800 ?

thanks

or lets say I have a 5520 wlan controller

how do i connect my aps to that controller to get a good speed through out and above 1gb ?

is it by having multi gigabyte switch everywhere?
