I know this is quite trivial, but I just want to know if all devices which support wiWi-fiFi through interface cards/hardware ( Likelike laptops/PCs/phones..etc) use CSMA/CA irrespective of their router/network if they share the same space? suppose, in a home,
Suppose there are 3 routers/which work as switches also,three WAPs. How do each of these routersWAPs know which sub-carrier frequencies to use, so that it does not cause interference? Will
Will all the devices (End-user devices and Network devices whichwhich are labelled with 802.11x) use CSMA/CA? As in when started, will they start sensing which frequencies are busy in the 2.4/5GHz frequencies and thereby choose one which is empty?
