Features

Accurate Indoor LocationThe tag transmits ultra-wideband (UWB) radio pulses which can be used by the Ubisense location system to find its position to within 15cm* in 3D. By using UWB, the system’s accuracy is maintained even in cluttered, multipath-rich indoor environments. The Ubisense location system is the only one capable of measuring both Angle-of-Arrival (AoA) and Time-Difference-of-Arrival (TDoA) of the tag’s signals, for increased accuracy and robustness.

Low-infrastructure Presence LocationUbisense tags employ a unique dual-radio architecture – in addition to the one-way UWB radio used for precision tracking, tags have a conventional bi-directional 2.4GHz radio for control and telemetry. In situations where the full UWB location system capabilities are not required, these radio signals allow the Ubisense location system to supply presence-level information for tags, indoors or outdoors, using a very sparse network of sensors.

Outdoor GPS LocationThe Trimode Tag incorporates a SiRFStar-based GPS receiver. When outside the location range of the Ubisense UWB location system, it will attempt to use GPS to find its location, and will relay that to back the Ubisense location system via its 2.4GHz radio.

Two-way CommunicationThe tag’s two-way 2.4GHz communication capability allows the Ubisense system to dynamically manage the tag’s update rate, flash the tag’s LEDs, report battery status and button presses, and wirelessly reprogram the tag to enable new features.

Flexible Update RatesThe Ubisense software platform allows the tag’s update rate to be dynamically and automatically varied depending on tag activity. When stationary, tags sleep to conserve power, an inbuilt motion detector ensures the tag transmits again when moved.

User Interaction FeaturesThe tag has a button to provide context-sensitive input to interactive applications..The application can also send feedback to the user via the tag LEDs that it received the button press

Rugged and AdaptableThe Trimode Tag is designed to be rugged, for use in harsh industrial environments. It is mechanically robust, dust- and water-resistant, and incorporates a variety of attachment mechanisms.

Long Battery LifeThe low current consumption and power management techniques result in long battery lifetimes. Status reports and alerts make maintenance easy and batteries are technician-replaceable.
