This document proposes and describes a Bluetooth-based location-aware advertising system for mobile phones. It discusses using Bluetooth beacons placed throughout an area like a supermarket to broadcast targeted ads and coupons to nearby phones. The system would track which phones view which ads to improve targeting without requiring any app installation. Two case studies are presented: distributing supermarket deals and providing an audio tour guide at a historic site by transmitting information and points of interest to visitors based on their Bluetooth location. The system aims to allow convenient, instant opt-in access to location-based information and ads through Bluetooth without changes to users' phones.
