Ultra-Wideband Real-Time Location System Hardware

Malisko has partnered with one of the industry’s most reliable real-time location system (RTLS) hardware providers, Sewio.

The industrial environment imposes high reliability and performance demands for precise indoor tracking, delivered by a real-time location systems (RTLS), that needs to meet high quality standards and provide an industry-specific feature set.

The range of indoor tracking technologies is wide, yet only Ultra-wideband (UWB) can provide the accuracy, scalability and reliability needed in process-planned production in which the cost of every minute counts. Unlike other tracking technologies, only UWB provides an accuracy of 30 cm with unrivaled reliability, even in harsh metallic environments.

The Sewio ultra-wideband (UWB) RTLS Platform consists of two types of hardware: signal transmitters, called Tags, used for tracking the entities and signal receivers, called anchors, used for receiving the signals from Tags.


Tags are small electronic devices that are attached to any object or individual that needs to be tracked. The tags serve as a transmitter, sending out blinks that are received by anchors and forwarded to the location server for calculating the tags’ positions.


Anchors are electronic devices that detect the UWB pulses emitted by UWB Tags and then forward them to the location server for calculating tag positions. To cover an area with an indoor tracking system, a set of anchors needs to be installed above the area to create the location infrastructure.
