Sub-meter accuracy
Typical positioning accuracy of 0.3–0.5 m — about ten times more precise than Bluetooth positioning based on signal strength.

Fewer anchors, larger coverage
A single anchor covers a diameter of up to 45 m and tracks up to 500 tags at once, with sub-second location updates.
Built on the Bluetooth ecosystem
Works with any BLE 4.0+ device — badges, wristbands, asset tags, watches and smartphones — at a significantly lower cost than UWB.
Location data stays with you
The positioning engine runs on your own infrastructure and delivers coordinates to your systems through an open API.

Technology
Three generations of indoor positioning
1st generation
Presence detection
Confirms only that a tag is inside a zone, without a continuous position.
2nd generation
Signal strength (RSSI)
Estimates the distance from signal strength: 5–10 m accuracy and unstable location data.
3rd generation · Crypto Locate
High-precision positioning
0.1–1 m accuracy and a continuous track of every person and asset.
Working principle
How the angle of arrival locates a tag
Each anchor has an array of antennas that measures the angle at which the Bluetooth signal of a tag arrives. The positioning engine turns these angles into coordinates on the map of the site.
Single anchor — 2D position
The anchor measures the pitch and heading angle of the signal. With the known height difference between the anchor and the tag, the engine calculates the X and Y position.
Several anchors — 3D position
Angles measured by several anchors intersect in space. The engine triangulates them into full X, Y and Z coordinates.

System
Anchors + tags + software = complete RTLS
The system is modular: you can deploy the complete solution, or add individual components to the infrastructure you already have.
01
Anchors
Mounted on the ceiling or wall, anchors with an antenna array measure the angle at which the signal of each tag arrives and compute the phase difference in real time.
02
Tags
Badges, wristbands and asset tags worn by people or fixed to equipment send a Bluetooth signal. Depending on the model, the battery lasts up to 5 years.
03
Positioning engine and platform
The engine turns the angles into coordinates, and the platform shows them on the map, raises alarms and passes the data to other systems through the open API.
Coverage for large and complex spaces
Anchors
Two anchors, one positioning engine
Both anchors track up to 500 tags at the same time and can be combined in one installation — the standard anchor indoors, the enhanced one in large halls and outdoors.

FAQ
Frequently asked questions
Performance figures are theoretical values measured in a specific test environment; results in a real installation may differ.
Typical accuracy is 0.3–0.5 m indoors, about ten times more precise than positioning based on signal strength (RSSI).
One anchor tracks up to 500 tags at the same time with sub-second updates, and a complete installation supports more than 100 000 tags.
From a few months to more than five years, depending on the tag model and how often it reports its position.
Bluetooth AoA reaches sub-meter accuracy on standard BLE hardware, so tags and infrastructure cost significantly less than with UWB, and existing Bluetooth devices and smartphones can be used as tags.
Yes. The positioning engine delivers coordinates through an open API (WebSocket, JavaScript and HTTP), so location data can be used in your own applications and platforms.
