speed lowering down

Muzaffar Iyad Boukai — Sun, 04 Jul 2021 03:05:28 GMT

as i know that if i have a "b" clientsin my network connected to my AP, they will definitely lower the connection of all my wireless clients.

so all "G" clint will connect at the speed of 11 mb

what about "N" "G" if i have a N AP with mix clint of N & G will the AP lower its connection of all wireless clints to 45 Mb ??

Yes.

The idea is that if 11n clients talk in 11n speeds. the 11g client will not even be able to figure out that this is wifi protocol, it will just be noise for them. So what 11n clients do as soon as one 11g is present in the area, is that they send an announcement in 11g speed to say that they will send a 11n frame right after that. So that the 11g clients know that the noise is a 11n frame that they cannot understand.

That's how all the protocols are inter-compatible

It's how 802.11 works so the root document is the RFC for the 802.11 standard. You can find various websites explaining it but Cisco didn't write a document about every aspect of the standards supported 🙂
