GPS and Bluetooth Low Energy (BLE) are the two most used technologies to locate equipment. They are not competitors: GPS locates assets outdoors and between sites, BLE locates them inside buildings. Five criteria help you decide which one each asset needs.
Key takeaways
- Range and coverage: GPS works anywhere outdoors with a view of the sky; BLE covers buildings with gateways or a smartphone, from a few metres to about 100 m.
- Accuracy: GPS gives a few metres outdoors but fails indoors; BLE locates by zone or room, about 1 to 5 m, below 1 m with angle-of-arrival antennas.
- Battery: BLE tags last several years or run battery-free on light; GPS trackers consume more and need tuned reporting rates.
- Cost: BLE tags are cheaper and have no data subscription; GPS trackers need cellular connectivity (LTE-M, NB-IoT or 2G).
- Best practice: use GPS for assets that travel, BLE for assets that stay on site, and one platform to see both.
GPS vs BLE at a glance
| Criterion | GPS tracker | BLE tag |
|---|---|---|
| Where it works | Outdoors, worldwide | Indoors and on site |
| Typical accuracy | A few metres outdoors | Zone or room, about 1–5 m |
| Infrastructure | Satellites + cellular network | BLE gateways or a smartphone |
| Battery life | Months to years depending on reporting rate | Several years, or battery-free |
| Recurring cost | Connectivity subscription | None per tag |
| Typical assets | Containers, vehicles, trailers, equipment in transit | Tools, trolleys, work-in-progress, medical equipment |
1. Range and coverage
A GPS tracker computes its position from satellites and sends it over the cellular network, so it works almost anywhere outdoors: on the road, in a port, on another site or in another country. It is the right choice for assets that travel.
Satellite signals do not go through roofs and walls. Inside a factory, a warehouse or a hospital, BLE takes over: a BLE tag broadcasts a short signal that fixed gateways or a smartphone pick up, typically from a few metres to around 100 m in open space.
2. Location accuracy
Outdoors, a GPS tracker is usually accurate to a few metres, which is enough to know which yard, site or parking area an asset is in. Accuracy drops near tall buildings and disappears indoors.
Indoors, BLE positioning is based on the signal strength received by several gateways. In practice it gives the zone or room, typically to within 1 to 5 metres; angle-of-arrival (AoA) antennas can go below one metre where needed. The required accuracy sets the number of gateways, and therefore the installation cost.
3. Energy consumption and battery life
GPS and cellular transmission use more energy. Battery life depends mostly on how often the tracker reports: a few positions a day, or only on movement or zone exit, lets a tracker run for years. The ivTrack Evo is designed for this kind of long-life use, including on aircraft.
BLE is designed for very low consumption: many BLE tags run for several years on a coin cell. Battery-free BLE tags go further by harvesting ambient light, like the ivBeacon EosFlex, which works under ordinary indoor lighting.
4. Cost
A GPS tracker costs more per unit and needs a connectivity subscription. A BLE tag is cheaper and has no per-tag data fee, but the site needs gateways (or staff with a smartphone app) to collect positions.
The right comparison is the total cost per tracked asset over several years: hardware, installation, connectivity, battery maintenance and platform licence.
5. Ease of integration and use
A GPS tracker is simply attached to the asset. The platform is then used to set reporting rules: how often to send a position, and on which trigger (movement, zone exit, stop).
A BLE project also needs a short site survey to place gateways. Once installed, adding a new asset only takes a tag and a few clicks.
In both cases, the value comes from the platform: map, alerts, history and integration with your ERP or maintenance software. inVirtus Cloud shows GPS and BLE assets on the same map, and can be queried in plain language from Claude, ChatGPT or Copilot through our MCP connector.
Which one should you choose?
- The asset leaves the site (containers, trailers, equipment sent to customers): GPS tracker.
- The asset stays inside buildings (tools, trolleys, test benches, medical devices): BLE tag.
- The asset does both: GPS outdoors and BLE indoors, managed in the same platform.
Frequently asked questions
Does GPS work indoors?
Not reliably. Satellite signals are blocked by roofs and walls, so indoor tracking relies on another technology such as Bluetooth Low Energy (BLE).
How accurate is BLE tracking?
Indoors, BLE usually locates an asset by zone or room, to within about 1 to 5 metres. Angle-of-arrival antennas can reach sub-metre accuracy where needed.
How long does a GPS tracker battery last?
It depends on the reporting rate. A tracker that sends a few positions a day or only on movement can run for several years; one that reports every minute needs regular charging.
Is BLE cheaper than GPS?
Per asset, yes: BLE tags cost less and have no data subscription. But a BLE site needs gateways, so compare the total cost per asset over several years.
Can GPS and BLE be combined?
Yes. Many companies track assets with GPS outdoors and BLE indoors, and inVirtus Cloud displays both on the same map.
