Hi Everyone,
I surfed cisco support forums and this is writing "20-30 client is proper per ap"..
But I have a classroom with 60mx20m size and 80-100 client inside of classroom.. Deployed 2 1600 series access point before and student complaining the connection problems.. I thinking about changing Access point, So which series would appropriate for my problem? (available series 2800,2700)
Thank you

2700 is alredy EoS, so its better to go with 2802 APs.
Also best is to do a site survey , site survey report will tell you the interference points & how many APs you will need in a hall.

Hi Sandeep,
Thank you for your reply..
Which feature or attribute of AP effect to client count. I just know MIMO

Hi,
There are many ...1. You are limited by the RF/medium. 802.11 is a half duplex. As each client is added, the bandwidth becomes half each time.
Normally cisco mention that you can connect 200 Clients per AP (Cisco's terms of client link or mac address) but reality is different.
Ideally for data you should expect 20-25 clients per ap and If you are doing voice / video on wifi then max 15 Clinet per AP.

Can really recommend this blog on understanding and designing bandwidth capacity for wireless, it also uses classrooms as an example:

The capacity planner may also be handy to you, where you are not designing for coverage but for density. Also important to understand your end device requirements like bandwidth requirements when designing your network.

Define "connection problems". Wrong username/password? No signal? Bad signal?
What kind of wireless clients?
What OS? Android? Apple? Windows?
Have you verified if the complains are true/false?

Hi Leo,
I carried out the study on you told.
- Problem was slow connection but when I examine charts bandwidth is not consume fully (I inferred from this my APs(1600) not responding 30+ clients)
- Client OS %30 mobile, %70 Windows(laptop) roughly
- All complains are not true :) you know students want to best always

Please avoid using an number of users per AP.
It is purely what the devices are doing, and what their capacity is.
Check out this blog: http://divdyn.com/wi-fi-throughput/
That being said I have seen APs in Universities using 30 students per AP doing good throughput per client. In uni they were running 3700s.
Keith Parsons said always but the best AP model you can, so go for the 3800 or 2800 AP.
