RTLS

Hybrid RTLS system to cover all your requirements and needs for tracking personnel, assets or vehicles.

Async UWB TDoA (Time Difference of Arrival)

Fully wireless and asynchronous TDoA algorithm, which doesn’t require clock synchronizations among RTLS anchors. 

Normally TDoA systems require clock syncing over Ethernet cables, which limits choices for the network equipment. No such limitation here.

High precision:
40-50 cm accuracy

Low power:
6-24 months on a single charge

Good scalability:
up to 500 tags per second per zone

Good range:
60-80 meters

TDoA requires only one broadcast TX message from each UWB tag for positioning. Comparison: TWR requires three messages between each UWB tag and each UWB anchor – 12 messages in total for 4 anchors.

The minimal amount of RTLS anchors for TDoA is three, but four anchors should be used for the best possible accuracy.

Default TDoA Setup

Leantegra UA-IX RTLS anchors are connected via Ethernet or Wi-Fi, power supply is organized via PoE or USB.

When to Use TDoA?

UWB TWR (Two-way Ranging)

The most accurate RTLS with precision of 20-40 centimeters for moving objects and 5-10 centimeters for static objects. 

Two-way UWB protocol enables commands between RTLS anchors and tags – for example: haptic feedback (vibro) or LED alerts.

UWB ranging is used for both RTLS scenarios and proximity scenarios, such as collision avoidance. 

Only two devices, tags or anchors, are required for UWB ranging.

The best precision:
10-40 cm accuracy

Two-way protocol:
haptic, visual, audio alerts

Good range:
60-80 meters

Ranging scenarios:
collision avoidance, proximity alerts

Default TWR RTLS Setup

Leantegra UA-IX RTLS anchors are connected via Ethernet or Wi-Fi, power supply is organized via PoE or USB.

Setup: UWB Ranging

Ranging can be organized between two UWB tags or between anchors and tags.

TWR Setup for Collision Avoidance, Proximity Alerts

On-vehicle tablet and UWB tag connected via Bluetooth, worker-side tag with haptic-visual alerts or Bluetooth connection to a worker’s smartphone.

No servers involved: low-latency setup for time-critical scenarios.

Tunnel RTLS (Reverse BLE RTLS)

Specialized 1D RTLS system developed for underground mines, where cable installations are problematic. Tunnel RTLS enables installations without cables for RTLS devices.

BLE beacons are mounted inside tunnels and RTLS anchors (locators) are embedded inside cap lamps or vehicles. Supported connectivity for the locator devices: Wi-Fi and LTE.

No cables for RTLS:
fully wireless installation

Excellent scalability:
RTLS for thousands of workers

Acceptable accuracy:
10-20 meters accuracy, enough for underground mines

Low-power BLE beacons:
24+ months
on a single charge

Default Setup for Tunnel RTLS: BLE Version

BLE beacons are mounted inside tunnels every 20-40-60 meters along a straight line. The locator devices inside cap lamps receive BLE signals and determine its location. 

Default Setup for Tunnel RTLS: UWB Version with BLE Mesh

Another configuration for the tunnel RTLS with higher precision based on UWB. 

UT-100 tags are mounted inside tunnels and operate as RTLS anchors with BLE Mesh data transmission. Extra power supply should be provided for UT-100 tags in this confguration.

3D RTLS and Zoning

Industrial areas might include mezzanines, ladders, elevators, towers or storage racks, where Z-axis (height) information becomes really important.

Leantegra UT-100 tag enables Z-axis for RTLS and zoning with the on-board barometer (pressure sensor). 

Z-axis is available for both UWB RTLS and BLE Zone Tracking to enable the most optimal RTLS installations in complex industrial environments.

No need to install any extra UWB-BLE anchors for 3D RTLS in your setup:
  • 3D BLE Zoning – just one RTLS anchor is enough
  • 3D UWB RTLS – three RTLS anchors are enough
Average accuracy for the barometer-based height tracking is 20-30 centimeters.

Smartphone RTLS

Leantegra-14

Mobile SDK for Android and iOS with reference applications.

Implemented indoor positioning based on iBeacon (BLE), indoor navigation and the remote tracking of smartphones on CVO Portal. 

Well-tested since 2015 on multiple projects related to BLE proximity marketing, indoor navigation and location analytics.

Mobile-SDK

Advanced algorithm for BLE RTLS:
1-2 meters accuracy

Feature-rich indoor navigation:
multi-floor routing and guidance

Fast indoor mapping engine:
optimized OSM rendering

Remote tracking:
track workers by their smartphones

Default Setup: Smartphone RTLS

At least three BLE beacons are needed for Smartphone RTLS within 12-20 meters range.

TETRA Integration (Terminal RTLS)

Software module for CVO Portal supporting the standard TETRA LIP and the proprietary Motorola LRRP protocols for location tracking and remote administration:

  • Track and map any LIP-compliant device, such as TETRA mobile terminals.
  • Motorola-specific parameters and settings for location reporting.
  • Inventory of TETRA devices is managed through “Devices” module of CVO Portal
  • Geofencing, alerting, location analytics and other common features of CVO Portal are available for TETRA devices.

Developed in partnership with Globberry.
