Ultra Wideband (UWB) is a wireless communication protocol. It uses radio waves in a similar way to Bluetooth and Wi-Fi. What makes UWB different to Bluetooth and Wi-Fi is the very wide band of several GHz that it operates in.
UWB can be described as a continuously scanning radar that can precisely lock onto an object, discover its location and communicate with it. A UWB transmitter will send billions of pulses over the wide frequency band. A corresponding receiver will then translate the pulses into location data. UWB uses extremely low power but the high bandwidth is ideal for transferring lots of data from a host device to other devices up to 30 feet away.
UWB can be used for many applications. In the early 2000’s it was used by the military in radars, covert communications and briefly as a form of medical imaging, for example to develop a remote heart monitoring system. Its primary use today is location discovery, because it boasts centimetre accuracy of geospatial data.
At Spatial Quotient, it was a long journey before we finally that UWB would be the most suitable technology to measure staff and patient movement.
We started our journey by using RFID (Radio-Frequency Identification) and although this worked for us and was a good starting point, it didn’t give us the level of detail that we required. After extensive research, demonstrations and testing, we decided to migrate to UWB. We did this because:
