UWB Tags for Indoor Location Tracking

In a real-time location system, (RTLS) tags are small electronic devices that are attached to objects that need to be tracked. The tags send out blinks that are received by anchors and forwarded to the location server for calculating the tags’ position. RTLS Tags are used for asset tracking, vehicle tracking, material flow analysis and employee location tracking for safety reasons.

As each vertical and use case bring in different tag requirements, Sewio developed three different tags to allow customers to choose the right tag to meet both their needs and budget. The design of the system also enables Sewio partners to further customize the tags.

For midsize organizations to enterprises that are struggling to increase their efficiency, Sewio RTLS tags provide a real-time tracking and identification solution. Unlike traditional indoor tracking technologies, only Sewio provides high accuracy together with a long tag battery life, enabling the tracking of thousands of tags within one area.

Sewio UWB Tags Feature Matrix

Features and Sensors Explained

Motion Detection: Turns the tag on as soon it detects motion, thereby increasing the battery life when the tag is at rest
BLE: Bluetooth (BLE) is used for easy updates to the tag’s firmware
NFC: Near Field Communication (NFC) is used for tag reconfiguration and commissioning/pairing the tag with the tracked object
ACC: Accelerometer (ACC) switches the tag on from sleeping mode
BAR: A barometer delivers precise atmospheric pressure measurement that is used for detecting the height position of the tag (Z axis)
OEM: Every Sewio RTLS tag can be purchased as an OEM (Original Equipment Manufacturer) version for fitting into a custom housing

Useful Tag Utilities

Sewio’s unique RTLS tags have a battery lifetime of 3-5 years. The calculator allows you to predict the battery lifetime based on the required refresh rate, RF profile and radio channel used.

While the overall number of tags within RTLS is unlimited, the tag channel utilization calculator tells you how many active tags can be within a single location cell at one moment.

Customizations and Extensions of Tags

Sewio UWB tags are ready-made for advanced extensions and HW/FW customization. The open design is easily customizable as the full source code and blueprints are available to Sewio partners.

The open design allows you to:

  • Connect your own tag design in Sewio RTLS TDoA
  • Send a custom payload from a tag
  • Add a sensor to a tag
