Operation
Ubisense tag modules transmit ultra-wideband (UWB) pulses of extremely short duration which are received by the sensors and used to determine where the tag is located using a unique combination of Time-Difference-of-Arrival (TDoA) and Angle-of-Arrival (AoA) techniques. The use of UWB together with the unique AoA and TDoA functionality ensures both high accuracy and reliability of operation in challenging environments.

Sensors are grouped into cells with additional sensors being added to a cell depending on the geometry of the area to be covered. In each cell a master sensor coordinates the activities of the other sensors and communicates with all the tag modules whose location is detected within the cell. By designing overlapping cells, it is possible to cover very large areas.

Development boards
The Tag Module Research Upgrade Package includes two tag module adapter boards  with batteries and also two Ubisense evaluation boards. The tag module adapter boards are used to test the location capabilities and features of Ubisense tag modules and the evaluation boards are used to evaluate the interfaces and functionality of the tag modules.

Series 7000 Tag Module
The Ubisense Series 7000 Tag Module provides the precise tracking capabilities of the standard Ubisense tag together with the ability to easily integrate that functionality into other devices. It is supplied with a 20-way (2 x 10) 1.27mm pin header, which provides for power supply, general input / output and serial data communication, enabling increased integration flexibility.

The Ubisense Tag Module has received certification as a plug-in radio device, simplifying emissions testing of finished products into which the module has been designed.

Software
Software supplied with the research package includes the distributed location processing software platform supporting visualization, system customization and application integration via an industry standard API.

The research package software also includes Ubisense Developer software which extends the Location Platform with a Motion Simulator for testing and demonstrating location-aware applications without needing a sensor system and a Data Dictionary editing tool that enables the development of new application-specific data models.

A Data Client graphical user interface application is also supplied which allows the user to send, receive and view data that is being sent to a tag module/accessory.

Training
Ubisense provides a two day training program for one user.  The training course is usually held at a Ubisense regional office and consists of tutorial, demonstrations and hands-on practice sessions.

Maintenance and support
One year’s system maintenance and support is provided with the package which covers bug fixes and basic functionality updates.
