Scanning the WiFi airwaves…

This page shows what the node measures in the air: which channels are crowded, how many routers sit on each, and how many devices passed through. Nothing here is modelled — the node hears what it hears.

If your own router sits on the busiest channel, moving it is the cheapest fix available. The crowded channel is the one to leave.

This counts MAC addresses, not people. iOS and Android rotate their MAC roughly every 15 minutes, so a single phone can appear as several addresses. Read it as activity in the air, not a headcount.
