Localization is one of the most requested features in a smart bag, but also one of the most complex to implement correctly. Modern systems use a multi-technology approach that ensures accuracy in every context.
Outdoors, the GPS/GLONASS module provides position with an accuracy of a few meters. The system supports both the American GPS and Russian GLONASS constellations, ensuring global coverage and greater reliability even in unfavorable conditions.
Indoors, where GPS signal is unavailable, Ultra-Wideband (UWB) technology comes into play. This technology enables centimeter-level localization, ideal for finding the bag in an office, restaurant or airport.
Bluetooth 5.0 works as a proximity technology: when the bag is within range of the smartphone, the BLE connection provides approximate distance information. If the bag moves beyond the user-set threshold, the alarm triggers immediately.
The transition between different technologies occurs automatically and transparently for the user. The companion app always shows the most accurate position available, indicating the technology used and the precision level.
A crucial aspect is energy management: the GPS module is the most power-hungry component, so the system activates it only when necessary. Under normal conditions, tracking occurs primarily via Bluetooth, ensuring up to 30 days of battery life.
