Ultra-Wide Band Technology

THE ENGINE FOR HIGH-ACCURACY POSITIONING

Ultra-Wideband (UWB) systems are based on a new radio technology that uses very low energy pulses for short-range, high-bandwidth communications over a large portion of the radio spectrum. It is a new revolutionary technology allowing to accurately determine the position of objects/persons with centimetre precision. This technology is particularly useful for indoor environments, where traditional GPS systems are completely unusable or characterized by poor accuracy. The UWB tags emit short electromagnetic pulses that allow localization in addition to the transmission of  data. The use of UWB technology is particularly suited for the manufacturing environments in which the problem of latency, and the electromagnetic interference are critical. Our engineers have been working at a hardware and firmware levels to offer unique architectures of this kind in the world.

Ultra-Wide Band

The UNISET products exploit the latest technology offered by the Decawave chip to create platforms for localization in indoor/outdoor environments.
Uniset products implement in a flexible way beyond state-of-the-art ranging, localization and tracking algorithms. Thanks to UWB technology it is possible to achieve higher accuracy than those obtained with similar technologies such as GPS, Wifi, etc

Two Way Ranging

The Two Way Ranging (TWR) technique consists in the calculation of the distance starting from the propagation time of the UWB signals generated by our radios. Th fusion of several distance measurements enable user’s localization.

Time Difference Of Arrival

The Time Difference of Arrival (TDOA) technique allows estimating the user position with a one-way signal transmission from anchor nodes. This approach enables an unlimited number of tags localized simultaneously with very high update rate.

Sensor Fusion

3D accelerometer, gyroscope, magnetometer and barometer data are offered
with our products and can be exploited for efficient positioning with enhanced-accuracy.

The UWB technology operates in frequency band of 3-7 GHz in 6 channels:  1,2,3,5 are defined with 500 MHz bandwidth, while channels 4,7 offer bandwidth of over 1000 MHz.
