New Chromebook lab, how many APs

We are replacing a computer lab with new Acer C910 Chromebooks. 

the lab they are going into is roughly 30 x 30. I was thinking of putting an AP 121 in two corners of the room.  

What's the best configuration for this?

Hi Justin,

How many Chromebooks will be in the lab?  How will they be used?  Will there be other devices in this area such as BYOD or teacher laptops?

There will be 30 chromebooks and no other devices except for students or teachers that may or may not have their personal device connected to the guest wifi lan. 

We are not a byod district

So if I understand you correctly there will be a mix of n and ac devices and the max # of concurrent devices connected will be about 35.  Most of the devices are AC (That's what the Chromebook specs stated.).  I am assuming that the Chromebooks will occasionally be used to stream HD video but, not all once, and will generally need about 3 Mbps each.

Consider setting a max bandwidth per device.  

The Aerohive planning tool can show the RF at different power levels so that you can visualize your cell sizes and choose the best location for the APs.  In an area that size, assuming a 10 foot ceiling height, 10 dBm on the 2.4 radios and 11 dBm on the 5GHZ radios are a good starting point.  In short,  I think that you can get away with two 121s on low power.

Personally I would not recommend putting AP's in corners. If budget allows, I would suggest a single AP230 mounted in the centre of the room below the ceiling void. Power can then be adjusted manually (or left on auto depending on your RF environment) to allow for better client density. 

As for bandwidth settings I will leave that your discretion, however the aforementioned 3mbps should provide sufficient throughput for streaming HD content.

I agree with Luke. A single AP230 or, even, an AP130 in the middle of the room mounted on the ceiling. I wouldn't restrict the bandwidth as those APs are petty capable but I would go higher then 3mbps - I'd proabaly go 10mbps if I needed to set a limit but it depends on what you internet bandwidth is. I have 3 of them covering a 10,000 Sq Foot sound stage quite happily. I haven't seen a really high capacity situation yet but they should cope with a couple of hundred connections.
