The options compared
| Method | Hardware | Typical accuracy | Needs an app | Upkeep |
|---|---|---|---|---|
| Bluetooth (BLE) beacons | Beacons every few metres | A few metres | Usually | Batteries, replacements |
| Wi-Fi positioning | Compatible access points | A few metres | Usually | Calibration surveys |
| Ultra-wideband (UWB) | UWB anchors + UWB phones | Sub-metre | Yes | High install cost |
| QR signs + phone sensors (MakeMyAtlas) | Printed signs only | Exact at each sign, drifts slowly between | No — browser | Reprint a sign |
When beacon-free is the right choice
If the goal is getting visitors to the right door — patients to clinics, shoppers to stores, travellers to gates — what matters most is a correct starting point and clear turns. QR signs at entrances, lifts and junctions deliver both, at zero running cost and with no app.
When you might still want hardware
Live asset tracking, staff location or sub-metre positioning in warehouses and factories justify installed infrastructure. For visitor wayfinding it is rarely worth the cost.
