[coreboot] how intel ME is connected to the internet ?

[Hendra]

hi coreboot,

I read in Wikipedia that Intel ME has an independent internet connection.
But what does "independent" mean ?

Is it an independent internet connection from the OS ?

or is it an independent internet connection from the network related
devices ?
such as: wwan card, wlan card, bluetooth module, wimax card

or maybe it has its own secret/hidden independent networking device,
so it can connect to the internet,
without depending on Laptop's networking device,
such as: wwan card, wlan card, bluetooth module, wimax card ?

regards,
