Trying to get my head around WIFI in a simple and practical way.
If I have multiple users that are varying distances from the AP and thus each get different band width (dynamic rate scaling) - does this mean that each and every users' throughput is downgraded to the furthest and slowest user?
I base this foolish idea(?) on what I have read in a Cisco text book which states it but does not explain it.
The logic of this is that it does not matter how close or good your signal is , even if you are sitting on the AP, your throughput is based on the user 40 metres away.
Cisco ".. Because wireless technology uses a CSMA/CA mechanism, all clients adopt the speed of the slowest client on
the access point. For example, if three wireless clients are attached to the wireless access point running at
24Mbps, and a wireless client some distance away attaches at 6 Mbps, all clients will run at the lowest speed!..."
