Geofencing and BLE beacons both detect presence, at different scales. Geofencing draws a virtual boundary using the GPS a phone already has, then acts when the phone enters or leaves, which suits large outdoor zones. BLE beacons are small Bluetooth Low Energy transmitters that broadcast an identifier a nearby phone can hear, which works indoors and resolves nearness to a specific point. Use geofencing for coarse, area level triggers, and beacons for indoor, point level proximity.
What each one is built for
Geofencing is presence at the scale of a place. Using the GPS a phone already carries, an app draws a boundary around a region and acts when someone enters or leaves. It needs no extra hardware and covers wide outdoor areas well, which makes it a natural fit for area reminders and location based triggers. The cost is precision: GPS is coarse, and it degrades indoors and in dense city blocks.
BLE beacons work at the scale of a point. A beacon is a small Bluetooth Low Energy transmitter that broadcasts an identifier over short range, at low power, for a long time on a small battery per the Bluetooth SIG. Any app that hears it can estimate how close it is, which is why beacons drive indoor wayfinding, aisle level context, and proximity analytics where GPS cannot reach. The cost is hardware: someone has to place and maintain the beacons.
Both stop at detecting that something is near. Parousya's patented method adds the next step. A Bluetooth broadcast, like a beacon, can be one of the short range transports it senses, but the method identifies the nearest correct provider and routes the transaction through a central server, so the two devices never connect directly. It works indoors where GPS fails, and nothing is sent until the customer acts, unlike continuous background geofencing. That architecture is covered by US10657515B2 and the divisional US11392923B2.
Side by side
| Dimension | Geofencing | BLE beacons |
|---|---|---|
| Scale | An area or zone | Nearness to a specific point |
| Underlying tech | GPS the phone already has | Bluetooth Low Energy transmitters (Bluetooth SIG) |
| Indoors | Unreliable, GPS degrades indoors | Works well indoors |
| Extra hardware | None | Physical beacons to place and maintain |
| Precision | Coarse, tens of metres or more | Close range near each beacon |
| What it senses | That a boundary was crossed | That a known beacon is nearby |
| Power on the phone | Background location can drain battery | Listening for a beacon is low power |
| Typical uses | Area reminders, outdoor triggers | Indoor wayfinding, proximity analytics |
Choose BLE beacons when
- The setting is indoors, where GPS is unreliable.
- You need nearness to a specific point, like an aisle or a doorway.
- You can place and maintain physical beacons.
Choose the proximity method when
- The trigger is area level, like entering a neighbourhood or a site.
- You want to reuse the phone's GPS with no new hardware.
- Coarse outdoor coverage matters more than indoor precision.
Common questions
- What is the difference between geofencing and beacons?
- Scale and technology. Geofencing uses GPS to draw a boundary around an area and acts when a phone crosses it. BLE beacons are physical Bluetooth transmitters that a phone hears when it is close, which works indoors and resolves nearness to a point.
- Do beacons work outdoors?
- They can, but their strength is indoors, where GPS based geofencing struggles. A beacon marks a specific spot, so it is common for aisles, entrances, and exhibits rather than wide outdoor zones.
- Is geofencing accurate indoors?
- Usually not. Geofencing relies on GPS, which degrades inside buildings and dense urban areas. Where indoor precision matters, beacons or other short range radio are the better fit.
- Where does Parousya's proximity method fit?
- Both geofencing and beacons stop at detecting that something is near. Parousya's patented method adds the next step. A Bluetooth broadcast, like a beacon, can be one of the transports it senses, but the method identifies the nearest correct provider and routes the transaction through a central server, per US10657515B2 and the divisional US11392923B2. Nothing is sent until the customer acts, unlike continuous background geofencing.
