Maximum number of users per AP

Hello Tac team!

What would be your recomended users per AP that you would recommend?

 

For example

If i got a dual band ap like a 105 as far i know its recommended 30 users per band  if they are just browsing and using internet in general.


If the user is using VOIP phones then that would be less maybe 20 users per band?

 

If they are using IP Camaras? maybe 20 per band also?

 

What about ip camaras and voip and users? haha

 

I bealive it all depends on the BW they are using and what kind of application... do you guys got like a formula or something like it?

For example if you using  X BW  per user and Y BW for 2 VOIP phones and 1 IP Camara? the result would be you can use that ap for Z ammount of users

 

What are your recommendations regarding this?

 

I also bealive that it also depends on the AP type as for example an AP 61 would be a way less.... maybe less than 15? and now i mention this i had that issue today....  there were 20 users in one ap 61 and there was soo much packet loose in that AP... i recommended the client to change it for a new AP 105  as they are all sharing 54mbs... and they are using internal apps...

 

Cheers

Carlos

Re: Maximum number of users per AP

It really depends on the radio and the channel busy. If we have have users on same channel and sharing the bandwidth. 

 

It is possible to have 30 users for optimal performance. In case you are using Voice , 20 would be ideal. If it is a combination then 12- 15 could give us expected performance.

 

 

Thanks,

Re: Maximum number of users per AP

Well now you mention that

What would be the channel busy ammount you would see to tell the client, you need another AP!

 

For the noise part i actually konw that if its less than -80 for example having -78 or something like that there is too much noise and we need to investigate that!

Re: Maximum number of users per AP

With 6.3, the load balancing would be able to determine what should be the target client per channel,

 

See below configurable ARM options,

 

(Aruba) #show rf arm-profile default | include Load
Client Match Load Balancing client threshold                                 10    <--- Target no. of clients to be maintained per radio
Client Match Load Balancing SNR threshold (dB)                          30    <--- Target SNR of neighbor radio, if available clients will be                                                                                                                                            balanced to the new neighbor radio

Re: Maximum number of users per AP

We'll need to run this by internally to verify the scale test numbers and update regarading specific ap types.
