Each prototype was more accurate, precise, and robust than the previous version. RADBEACON DOT UPDATE FREQUENCY SERIESOur R&D team developed Leverege’s Location Engine through a series of prototypes. Indoor RTLS solutions require not only tuning hardware to the nuances of each physical space but also creating dynamic and reliable positioning algorithms.

It is also significantly more cost effective than other WiFi + Bluetooth microcontrollers. By lowering the Tx power, hubs that are farther away are effectively filtered out by being “out of range.” Having a configurable Tx power provides a way to experimentally determine the optimal tag settings for a particular environment.įor the hubs, while there were many programmable microcontrollers with built-in WiFi and Bluetooth chips, the ESP32 development board has extensive documentation and support via its open source community. Because RSSI is easily attenuated by multiple factors, this can create ambiguity in location determination.
