RF-based technologies have served as the backbone of location-tracking for years, but engineers are looking for new options that can overcome the limitations of these technologies such as security vulnerabilities with RFID or the rigidness of near-field communication (NFC). Bluetooth ranging technology, which uses the distance between one or more devices through signal properties or packet transmission details, can increase the accuracy, simplicity, and security of many location-based applications. This whitepaper reviews the details of using Bluetooth technology in location-based applications and dives into the options for extending ranging technology.
