Overall CCQ of a channel and Max Throughput

Hey Everyone,

Does anyone know what the correlation is between the overall Channel CCQ and the Max Throughput capabilities of that channel?

Example:

If I see an overall CCQ on the channel with 20 clients at 90, how much throughput can I push through the channel?

If I see an overall CCQ on the channel with 20 clients at 97, how much throughput can I push through the channel?

This is with a 2.4 Ghz B channel at 20 Mhz wide, with no encryption.

Thanks for your help…

As higher is CCQ value as possibly higher (closely to the maximum) bandwidth rate you can get (theoreticaly).

CCQ is showing how effectivly is used ‘air interface’.
ccq is weighted average of values Tmin/Treal, that get calculated
for every transmitted frame, where Tmin is time it would take to transmit
given frame at highest rate with no retries and Treal is time it took to
transmit frame in real life (taking into account necessary retries it took to
transmit frame and transmit rate)

Thank you Sergejs for explaining CCQ values to me.

Now… What is the theoretical maximum throughput of a 2.4 Ghz Channel at 20 Mhz wide operating in B mode?

If I knew that I could calculate what the capabilities are.

6MBPS actual thoughtput on B on a 20MHZ wide channel.

Thank you sir!!

Now I can calculate what my actual capabilities are in real time.
