Maximum number of wireless client for 1600, 2600 and 3600 APs

Anyone knows what is the Cisco reccomendation for the maximum number of wireless client each Access Point can support? This is with reference to the new 1600, 2600 and 3600 access points.

Based on the cisco datasheet, the maximum clients that each AP can support for clientlink is 32 for 1600 and 128 for 2600 and 3600. I'm looking for some reccomendation from Cisco. I tried finding it under the design guide but it did not mention anything about this.

I know that Aruba reccomends 30 clients per AP.

Rule of thumb is 25 clients per AP.

However, it will depend entirely upon what traffic you are expecting.

If you are doing nothing but simple HTML, emails, chat, then this figure can go up to 35.  You want to do HD video then think about going down to 8 clients per AP.

What about this document: 'The New Generation of Cisco Aironet Access' which states that the newer APs can handle up to 200 max clients per radio?

Lets keep in mind the issue here is not the AP, but more the medium (air). You can only fit so many bit in the air at a given time. More clients mean more bits. When 802.11ac comes to maturity you will be able to see higher density becuse you can transfer these bits faster allowing more clients to use the air. So to speak.

What George has said is one of the main reason why the rule-of-thumb is set this low. 

The document where you quoted were written by Marketing folks and their main objectives is to SELL. 

The rule-of-thumb that George, Steven, Scott and I have noted are PROVEN FACTS and in REAL WORLD SCENARIOS.

Do you have any whitepapers for the real world scenario that you could share?

Re: Maximum number of wireless client for 1600, 2600 and 3600 AP

Read up on CSMA CA

I bet to differ this is not pure marketing numbers. 

Dave,

Let me help you to  make things easier for you. Lets start with 1600. As per datasheet it support 300 Mbps/radio.

Now we know wireless work on half duplex . 300/2 = 150Mbps. Wifi uses CSMA/CA so 150 Mbps will be shared by all client connect to AP either one of radio. Let to be safe assume it is 5Ghz band radio.

Now let discuss average bandwidth contract for different service.

Full HD video - 5 Mbps

Regular Video - 2.5 Mbps

Data (email/web surfing/etc) 1Mbps

Handheld scanner - 10-15 Kbps

Voice - 12-16 Client per AP at max recomended is 8 client

With available 150 Mbps theoratically with simultaneous access we can have 150/5 = 30 users per AP. Remember when we plan number of client we always consider best experience for support services. Example Voice/HD Video/Regular Video .

Similarly if we have regular video requirement then 150/2.5 = 60 users . At the same time you also have to remember external factors which may downgrade available bandwidth contract per user.

When Cisco document says 200 user at max they may be referring to handheld scanner type of user where at any moment per user bandwidth requirement is limited to Kbps.

This is rule of thumb and applicable to any vendor Access Point. ie You need to consider couple of things before you commit any bandwidth availablity to end your user.

- Service type (Voice/HD Video/Regular video/Data/Scanner)

- Radio band (2.4/5Ghz)

- Floor Noise

- Channel utilization

- User density /Behaviour
