Hi. I'm a networking student from a school trying to recommend our management to upgrade the school hostel network. I've designed a network diagram for my suggestion to our school management.

During the Teachers and Parents Association meeting, I've heard that they're suggesting to use 6, 30Mbps WAN connection. Our hostel have 7 blocks. Which means, our hostel is going to have 6 routers, 1 for each block (only 1 hostel block won't have a router). I felt like this is a ridiculous approach by them (idk maybe I'm wrong).

Here's the new network diagram I'm suggesting. The scale in diagram is traced from Google Maps.

Our network are going to be used by around 450 students. So, I'm suggesting to use 2, 800Mbps WAN connections since it could increase the bandwidth, right? I suggesting to give each student only around 5-8Mbps connection (controlled with pfSense).

For the network devices, I'm thinking of using Netgate 5100 for our router/firewall since I like to use pfSense.

For our access points, I believe TP-Link Deco X20 AX1800 could do the work. Each block will have its own access point + one access point for our hostel mosque (green square in the network diagram). It will be powered by wall. I would like to have the mesh feature which each router is connected with Ethernet backhaul for reliability than using WiFi backhaul. These access points have AX WiFi which I think good for a long run.

To connect all of these switches, TP-Link TL-SG105 would be used. Since we're not using VLANs (I think), unmanaged switches is going to be our choice. This switch also support 1Gbps connection for every port. We will use UTP CAT5E for our local connections. For WAN, fibre will be used by our ISP.

I hope I could get feedback and suggestion to improve my plan. The lesser the cost, the better since we don't actually have a big budget.

Thanks a lot for your time.
