Future Directions

Researchers are exploring ways to overcome these limitations, including:

• Building networks of receivers: Using Arduino, Raspberry Pi, or ESP32 boards to build networks of receivers that can improve the accuracy of the beacons in sparsely populated areas.
• Increasing the number of beacons: Deploying more beacons in the wild can improve the accuracy of the trackers, as more mobile devices will report locations to the central base.
• Improving signal strength: Researchers are working on improving the signal strength of the beacons, which can reduce positional errors and improve overall accuracy.
