DIMENSION4™ UWB Real-Time Location System (RTLS)
At Ubisense we’ve dedicated ourselves to perfecting a best-in-class, precision location system using Ultra Wideband (UWB) technology.

DIMENSION4™ is the result of decades of experience delivering industrial-scale, real-world solutions that pin-point the true 3D location, movement and identity of people and things in critical processes.

Centimetre-level accuracy in three dimensions, even in cluttered, indoor industrial environments.

In-production systems with 1000’s of sensors processing 1000’s of location updates per second.

Tag battery life up to 15 years and self-monitoring to alert when a replacement battery is due.

Ultra-Precise. Ultra-Reliable. Ultra-Wideband.
Only DIMENSION4 measures both Time-Difference-of-Arrival (TDoA) and 2-axis Angle-of-Arrival (AoA) of UWB signals in the same system, providing up to 3x more location information than comparable systems.

Accurate 3D tracking information is possible when only two sensors detect a tag, reducing the infrastructure requirements and minimizing cost.

Advanced filtering algorithms select only the most reliable measurements from the excess of location data, providing an unmatched ability to cope with obstructed and reflected signals.

Reliable, accurate location. Every time.
