WiFi position, monitoring, locate device via network signal
This idea is feasible with some setup. You can use the Wi-Fi router to manage connections, assign MAC addresses to students, and sync attendance in a database. Since each router supports only a limited number of simultaneous connections, you can batch students—connecting them in groups at a time. When a group connects, match their MAC address to your database, record attendance for that session, and then set a timeout so the device waits before the next class starts. This way, the cycle can repeat throughout the day. Let me know if you need more details on implementation!
Wireless consumer APs typically manage about 100 idle or lightly loaded devices before performance drops, so for big classes a basic router like Archer C7 might be better. For connection timeouts, adjust your DHCP lease duration to be just under the class length—e.g., 1 hour if the session is 65 minutes. This ensures new devices receive IP addresses when they connect. You can also widen your DHCP range to avoid running out of IPs as devices are frequently added and removed.
An Access Point would work better. Using Bluetooth could be preferable, allowing you to capture each device's address and scan for nearby ones on a computer.
