AMBIENT-6G

This use case aims to help users locate lost personal items (like keys, wallets, or headphones) within their home using A-IoT technology. It introduces small, low-cost, energy-efficient END tags that can be attached to personal belongings. These tags don’t need batteries—they harvest energy from RF signals emitted by the user’s smartphone or other devices.

When an item is lost, the user activates a search via their smartphone, which sends out an RF signal to power the END tag. The tag then uses RF backscatter modulation to respond, allowing the system to estimate its location using techniques like triangulation or signal strength analysis. While not as precise as GPS, this method provides approximate location guidance to help users find their items quickly and with less stress.

This solution is sustainable, low-maintenance, and enhances daily convenience by reducing time lost and anxiety caused by lost belongings.
