How many clients support access points 1602, 2602, 3602?

Question

Hi! How many clients support access point 1602, 2602, 3602. I have found for example that the 1602 supports 32 ClientLink clients and max 128 clients, APs 2602, 3602 supports 128 ClientLink clients and max 200 clients. But is it really? And can we say for example that the AP 2602 will withstand max 200 clients?

Answer 1

The reason the answer varies so much, is because there are so many variables (this is also why the value ranges so much from one manufacture to the next).  When determining the answer you are looking for you need to consider the following factors and likely more:
AP model and the features it supports
single, dual, or tri radio AP
20, 40, or 80Mhz wide channels
Device type (b/g, b/g/n, a/b/g/n, a/b/g/n/ac, spatial stream support, and channel width support)
Security/QOS method(s) employed
Average distance from the AP
Obstructions between devices and radios
Number of competing radios for the same channel
Data rates configuration
Rogue detection/mitigation configuration
Surrounding client density not just the area of concern client density
Noise floor levels
Application types/per user network load (is it heavy like YouTube traffic or a drone on the network like Pandora)
Network latency on the switching side - including the internet circuit
Application of per SSID, per user, and or per application rate limiting
The list continues, but I think you get the idea
I have personally seen 80 devices on a 5Ghz radio of a 3500 access point with several other access points and at least 200 other clients in the area and it was working well.  That being said I would never design to expect that many on a single radio, but I think it is better said that you can safely design for 20-30 clients per 2.4Ghz radio and 25-40 clients per 5Ghz radio.
The default statement of 20-25 per AP and similar low expectation statements concerning Cisco wireless have been around for many years.  It is now 2014.  About 65% of clients support 5Ghz, ~9% support AC (already), ~90% support some form of N, and ~0.01% support B only.  The landscape of wireless is changing fast making questions like this one have ever changing answers.
I hope this helps :).
