Geolocalisation technologies
A full smart tracker makes sense for high-value equipment. But components, tools, and load carriers that cycle through an operation daily are a different story. They are too small for a tracker, too numerous to justify the cost, and too easy to misplace. BLE geolocation technology changes that.
BLE is built around one idea: use as little power as possible. Unlike the Bluetooth in your headphones, a BLE tag sleeps almost all the time and only wakes for a split second to send a tiny signal before dozing off again. That’s how a single battery lasts 3 to 10 years in a tag small enough to sit in the palm of your hand.
That matters because the tag never needs charging, maintenance, or swapping out. Stick it on once and it keeps announcing where it is, picked up by smart gateways that pass the location to the cloud. It works indoors, in warehouses, on docks, and in transit.
How BLE works — full technical explanation →
Smart trackers cover your high-value equipment. BLE location tracking extends that same visibility to the smaller, high-volume assets that are too numerous or compact for a full tracker: tools, load carriers, components, pallets. Here's what changes when nothing stays dark.
No more walking the floor to find a pallet, a tool, or a load carrier. Open the dashboard, see where it is.
Assets that leave their zone trigger an alert. You find out in seconds, not at the next stock count.
Every loading event has a timestamp. When a dispute comes up about what left and when, the data is already there.
When you know where every asset is, you stop ordering replacements for things that were never actually lost.
A location tag on its own is just a beacon. It sends out a short signal every few seconds and hopes something hears it. That something is a smart gateway. Without one, there's no data, no location, nothing to look at. Here's how it actually works.
The location tag wakes up briefly, sends out a small BLE signal with its unique ID, then goes back to sleep. That is all it does. No GPS, no cellular, no Wi-Fi. Just a short pulse that costs almost nothing in battery.
A nearby smart gateway hears the signal and logs the detection. Each gateway covers a zone: a warehouse aisle, a dock door, a production bay. If your tag is in range, the gateway knows it is there.
The gateway sends the detection to the Sensolus platform over its own cellular connection (LTE-M or NB-IoT). No reliance on building Wi-Fi, no IT tickets, no network setup. It just works.
Smart gateways pick up signals from location tags and send that data straight to your platform. Mount them inside your facility for zone-level visibility, let a smart tracker in a vehicle do the same job on the road, or use handheld mobile devices your team already carries.

BLE tags work well. The challenges tend to show up in the system around them: keeping gateways connected when site Wi-Fi drops, resolving conflicting signal reads into a single location, capturing transport events accurately, and making sure each tag stays tied to the right asset. These come up consistently in deployments that rely on standard BLE infrastructure.
Small enough to go on almost anything, with a battery that lasts years. That part is genuine and it works. What vendors leave out is the infrastructure layer behind it: the smart gateways that pick up tag signals, the network they use to stay online, and the platform logic that turns raw detections into reliable location data. That layer determines whether you get useful data or expensive noise.

Read customer story →BLE (Bluetooth Low Energy) is a wireless technology that sends small bits of data without draining a battery. BLE asset tracking puts that to work: attach a small location tag to any asset, like a pallet, a tool, or a piece of equipment, and it continuously broadcasts its presence to nearby smart gateways, which forward the data to a cloud platform. The result is a live view of where everything is, whether that’s in a warehouse, on a production floor, at a loading dock, or on the road.

A GPS smart tracker works independently: it determines its own position from satellites and sends that data directly to a platform over cellular. A BLE location tag is passive, it broadcasts a signal that smart gateways detect and forward to the cloud. Smart trackers suit high-value assets that travel long distances. Location tags suit smaller, high-volume assets where a full GPS tracker is too large or too expensive to justify. Sensolus offers both on the same platform, so you get one view of your entire asset pool.
BLE tags are designed around minimal power use. Because they spend most of their time asleep and only wake briefly to broadcast a signal, Sensolus location tags run 3 to 10 years on a single battery without replacement. No charging needed, no maintenance cycle.
Yes. Most BLE tracking systems rely on Wi-Fi-connected gateways, which means the whole system goes down if site Wi-Fi drops. Sensolus smart gateways work differently. They have their own connectivity, independent of any building network, so they keep working regardless of what happens to the site Wi-Fi.
BLE asset tracking is used across both industrial production and logistics. Any operation that moves high volumes of smaller assets, like load carriers, tooling, components, pallets and returnable packaging, through defined zones is a good fit. Common industries include automotive, aerospace, HVAC, food and beverage, pharma, and third-party logistics. BLE location tags are also frequently used alongside GPS smart trackers, covering the indoor and short-range portion of an asset’s journey while the smart tracker handles the long haul.
