Silicon Labs’ {hardware} and software program platform makes use of Bluetooth LE units to simplify angle of arrival (AoA) and angle of departure (AoD) location providers. The software program maximizes the location-finding capabilities of the BG22 household of Bluetooth LE SoCs and SiP modules. These tiny, low-power units function for as much as 10 years on a coin cell battery, whereas the software program can monitor property, enhance indoor navigation, and higher find tags with sub-meter accuracy.
The brand new software program options asynchronous fixed tone extension (CTE) broadcasts from the machine to the locator. Asynchronous broadcast eliminates the necessity for synchronized transmission timings between the machine and locator. This permits locators to trace a lot of property concurrently and a number of locators to concurrently see the identical asset on the similar time for triangulation. The software program additionally helps broad spectrum CTE broadcast throughout all 37 channels to scale back interference by shifting the CTE transmissions from commercial channels to information channels.
Silicon Labs’ Bluetooth Location Providers platform contains a number of components, together with:
