[WLANware] hello and basic question about multi hop bandwidth loss

[ZioPRoTo (Saverio Proto)]

Hello,

yes if you have something like this

Cable      -----------
Wireless ::::::::::::::::::

Node -----------Node :::::::::::::::::: Node
-----------Node:::::::::::::::::: Node

then you have no bandwith loss

of course the antennas connected with cable must be in the same roof ;)
