This document discusses micro-location and iBeacon technology. It defines micro-location as proximity detection rather than GPS-based location tracking. iBeacons use Bluetooth Low Energy signals to detect proximity within a range of around 50 meters. The document outlines some potential uses of iBeacon technology, including mobile apps that can provide contextual information, alerts or notifications to users when they enter or exit an iBeacon's broadcast region. Examples mentioned include retail apps that can provide shelf-level product information, museum apps that share exhibit details, and indoor navigation assistance.
