What Ubudu is
Install once. Find, act, extend.
Ubudu designs its hybrid anchors, tags and location engine together, so every later use runs on the installation you start with.
01 · Find
Precision where it matters
UWB on the lines and racks that need it, BLE across the rest of the site, one tag for both.
02 · Act
At the asset, not just on screen
Pick-to-Light on the tag, zone alerts and webhooks into your systems.
03 · Extend
One network, more uses
Add zones, BLE assets or Pick-to-Light later, without re-cabling or a second system.
How it works
How hybrid RTLS works: perceive, locate, reason, act.
01 · PerceiveHardware
Hybrid anchors and tags cover the site.
UWB TDoA locates a tag to under 50 cm in industrial or complex environments, under 20 cm in controlled ones. BLE adds zone-level presence in the areas between. Every tagged asset and person appears on the live map.
See anchors and tags02 · LocateLocation Engine
One position per tag, from UWB and BLE.
The location engine computes positions ten times a second, and every alert, map and report reads from that stream.
Explore the software03 · ReasonRules & Spatial AI
Rules turn positions into events.
Each rule watches for a zone entry, a dwell time or a movement, and raises an alert when its condition is met. AI assistants can ask about live positions in plain language.

Pick-to-Light turns a dot on the map into a light.
Click the asset on the map and its tag's LED blinks, so the right one stands out even on a crowded shelf.

The platform
One system, from anchor to API.
Positions and alerts reach your systems over REST, WebSocket, MQTT and webhooks, on your own servers or in our GDPR-compliant European cloud, with Ubudu or compatible third-party devices.

Adjust over time. Start with always-on BLE presence, use UWB where a process needs precision, and Precision Finding to reach one asset on foot. Update rate is tuned per site. Need presence only? Choose BLE tags from a large catalogue, including compatible third-party devices. Under high ceilings, BLE AoA anchors locate them to 0.5-2 m.

What customers say
Simple to adopt, easy to extend, built to scale.
Since December 2025, Safran Electrical & Power has relied on Ubudu's real-time location tracking technology to enhance the management of customer returns. In a business environment where responsiveness is essential and every minute matters to avoid AOG (Aircraft on Ground) situations, the solution allows us to quickly locate our assets and speed up the initiation of repair activities once quotations have been approved. Beyond asset tracking, the Ubudu platform provides real added value through advanced flow analytics and innovative AI-powered capabilities. The Ubudu team's customer-focused approach and continuous commitment to innovation have made this collaboration a genuine partnership. Their ability to listen, understand our operational needs, and continuously adapt the solution is a key enabler of our Manufacturing 4.0 transformation.
Ubudu has enabled us to secure pedestrian movements in our sorting centres in a simple, quick and large-scale way. This solution is more easily adopted by our employees, unlike the more expensive and limited solutions we had previously deployed.
Ubudu hybrid RTLS platform provides us the necessary flexibility to go-to-market and address different customers’ needs with competitive offerings. With its out-of-the-box applications and tools, the solution is easy to deploy and customer onboarding is smooth.

FAQ
Hybrid RTLS questions, answered.
How does RTLS work?
A real-time location system (RTLS) puts a small tag on each asset, vehicle or person. Anchors fixed to walls or ceilings pick up each tag's radio signal. With UWB TDoA, the location engine compares when the signal reaches three or more anchors and computes positions ten times a second. Positions appear on a live map and reach your own systems through REST, WebSocket, MQTT or webhooks.
What is a hybrid RTLS, and how is it different from a standard RTLS?
A single-technology RTLS offers either UWB precision or BLE coverage. Ubudu's hybrid real-time location system puts both radios in the same anchors and tags: UWB for precision in the zones that need it, BLE for presence everywhere else, one platform for both. Extending the site later means adding zones, not a second system.
Is my data secure?
Your data stays where you choose: on your own servers (on-premise) or in Ubudu's GDPR-compliant cloud in Europe, with data-centre hosting in Asia-Pacific and North America as options. The architecture is the same wherever it runs. The RTLS API requires an API key or a Keycloak token, and an access control server sets role-based permissions and acts as the OAuth2 provider.
How accurate is RTLS: UWB or BLE?
It depends on the technology and the site. With UWB TDoA, expect under 50 cm in industrial or complex environments and under 20 cm in controlled ones. BLE gives a zone-level position, 2 to 5 m, and BLE angle of arrival locates a tag to 0.5 to 2 m. To find one specific item, Precision Finding on the Hybrid Tag 4.0 guides you to within about 10 cm through an iOS app.
Can Pick-to-Light and shelf labels run on the same system?
Pick-to-Light, yes: select an asset in the RTLS software and its tag lights up (on tags with an LED), with the command sent over BLE through the same installation. Electronic shelf labels are driven by your RTLS too, but through partner hardware: Ubudu supports two label providers, Minew and PDI, behind one interface, and each uses its own label gateway. One PDI gateway serves up to 10,000 labels.
RTLS or RFID: which do I need?
Passive RFID records that an asset passed a reader, at a gate or a dock door. An RTLS also follows it between checkpoints: UWB for precise positions, BLE for zone-level presence. Choose RFID for checkpoint counts. Choose an RTLS to know where an asset is now, and to make its tag light up.
