Narrowbits TRACE · Indoor positioning UWB · DEMO 2026
Locate assets and people inside your facilities.
Two levels of precision where GPS can't reach: zone-level with Bluetooth and, with UWB, the exact position within each zone. Hospitals, plants, warehouses and distribution centers.
Indoor Positioning · BLE · UWB
The problem
Indoors, GPS doesn't work.
Searching wastes time
Mobile equipment, tools and carts that nobody can locate.
Staff safety
Know which zone each person is in during an incident, and who entered a restricted area.
How it works
Zone-level or pinpoint: depending on the decision you need to make.

BLE tells you which zone each tag is in. UWB tells you where it is within that zone. We define which one fits based on floor plans and goals.
What it looks like
Zones and positions on the same floor plan.
BLE zones and UWB positions over your facility's floor plan, with restricted-zone alerts. The real dashboard is shown in the demo.

UWB demo program
We're looking for the first sites to demonstrate TRACE UWB.
Throughout 2026 we're running on-site demos: a defined area, tags on assets or staff, and the live floor plan. Founding sites get preferential terms once the product is available.

Frequently asked questions
What customers usually ask.
How precise is it?
With BLE, zone-level: which area each tag is in. With UWB, the position within the area, around 10 cm according to the manufacturer. Actual precision is measured at your site during the demo.
Is UWB available yet?
We're running demos during 2026. Zone-level BLE positioning is available today.
What infrastructure does it require?
BLE: one hub per zone. UWB: anchors per area, based on floor plans and obstructions. Both run over LoRaWAN coverage.
How long do tag batteries last?
It depends on the reporting interval; this is defined during design.
Does it integrate with other platforms?
Yes, via API or MQTT.
