Coverage of many users in dense area.

I have a problem that I am looking for solutions to. We are a small, private University. So, our funds are limited and are need is huge.

Problem is we have an off-campus building, that is apartment style, with many users using multiple devices. Basically, we assume all devices are trying to connect wirelessly. We need to support 2.4GHz and 5GHz connections. We assume all users have at least 3 devices; laptop, phone, and a game/tablet/etc.We need to be able to support peak times with decent quality connection of all the users. I estimate peak devices to be around 150 - 180 devices at once. So, we need enough access or throughput to serve all of those users; we also need it to be budget friendly.

Current setup is a Comcast (Cisco) modem/router in every suite, 22 in one building. They only support 2.4GHz so there are about 3 on each 1, 6, 11 channels on each floor. This causes plenty of interference problems. Each modem/router has 25 Mbps connection through Comcast, connection to the WAN does not seem to be our current issue. Instead keeping users connected or getting them connected to the wireless seems to be the main issue here. We have already thought of running out fiber from main campus and wiring the building for Cisco APs (current deployment on campus) to connect it to our network, too much money unfortunately! Anyone have any thoughts ideas that they have heard/seen that can help spark an idea for us.

Thank you in advance to anyone willing to give input. Estimated specs are below and yes we estimated high.

2-3 students per room
2 rooms per suite [Estimate 4-5 students per suite]
6 (1st for) or 8 (2nd/3rd flr) suites per floor [Estimate 35 students per floor]
4 Buildings (3 Floors per building or 22 suites) [Estimate 100 students per building]
Estimated 300 devices per building (3 per user) with 150 - 180 on at peak times.

Check out Ubiquiti networks products. They have nice AP units that are much less expensive than Cisco.

Or, you could replace some of the existing units with ones capable of 5Ghz. which has many more channels to use.

Thanks for the lead there. Been on Google researching solutions up and down. First time I think I have gone past the 4th page of results. Ubiquiti seems amazing we spoke with them more about the product. Their only fear is on how it would be set up. Unfortunately, each room that has an access point in our scheme would be individually connected to the ISP. As if you and everyone in your neighborhood shared Ubiquiti wifi Access on one SSID, but had your own ISP hook ups. To this they said everything should work, but if one AP goes down it could cause major problems.

One of our issues is its a rented building and we can not run anything permanent. So our only options seems to be have individual connections to Comcast (monopoly in the area so no way to change service). We thought of using MoCA, but all the lines run directly back to the pole from each apartment. We just truly need something capable, cheap, and one of our main goals is to not have to run out there every time someone has an issue. We just do not have the time for that.

Any other thoughts out there?

Turn off most of the wireless networks to reduce interference.

If individual apartments are not paying for service, then it makes sense to have them share fewer access points.

Also look at upgrading existing devices for 5Ghz?
