How many devices per Access Point

I have a business environment where I will have around 100 ipads and 100 smartphones in one single room. Across the hall there are two rooms with about 30 ipads and 30 smartphones each. I was looking at the business class Netgear Access Points: http://netgear.com/business/products/wireless/business-wireless/

I guess I am confusing devices, connections and clients. How many devices, (ipad, laptop, smartphone, etc) is supported per Access point. Is it common to have more than one AP in a single room?

A simple wireless Linksys can connect 250 devices. I would suggest one for each room/side of hallway. Maybe use some kind of MAC Auth to keep other unwanted devices off your network.

Wow I would NEVER ever connect 250 clients to an AP simultaneously - there would be no bandwidth available for clients to get a useful service, even if it's just to obtain an IP address.

Generally the rough figure is 20-25 clients at the very most per access point.  Even then I'd only really do this on a dual-band, dual-radio access point.  That would give me the ability to connect around 12-13 clients per radio in the AP.

So in a room with 100 clients I'd want at least 4 APs.  5GHz would be the preferred band to use.

What about the data sheet on the 660 and 620 in the link I provided? The data sheet shows up to 128 supported clients. Is this not accurate?

Technically it is possible; the MAC table will allow 128 clients simultaneously, however the realistic throughput with that many clients would be so low you'd not be able to achieve even dial-up modem speeds at best if all clients were trying to use the AP at the same time.

Ok. I'm understanding. Let me ask this then. If I have multiple AP's in the same room, what regulates how may clients actually connect to each one for best performance. In other words, If I have four AP's in one room, what is to say that one AP will not try to provide all the connections? How are the connections divided between the AP's?

Thats why I said to use MAC Authentication. If user A comes into the office he will only connect to AP1. If user Z comes in he will connect to AP4. I only said a Linksys would do 250 as a example.

Craig BeckCommented:
You can't do MAC authentication if you don't know the MAC addresses of the devices beforehand.

Usually we set a different SSID on each AP if we want to determine which AP people connect to, otherwise we can use a controller-based system which can do dynamic client load-balancing.

I cannot use the mac address method because the devices will travel throughout the building and will need to connect to any available AP. I will look into the load balancing. Thanks.
