This document summarizes a research paper on using beacon technology for proximity marketing. It describes a system using Bluetooth Low Energy beacons deployed throughout a large shopping store to detect customers' locations via their smartphones. The system aims to deliver personalized mobile advertisements and promotions to customers based on their real-time locations in the store. It consists of beacon devices, a smartphone app, and a server component. The app detects beacons nearby to determine a customer's position and sends this data to the server via WiFi. The server then sends targeted ads to the customer's phone. The document outlines the system architecture and discusses how beacon technology and RSSI values are used for indoor positioning and proximity-based notifications.
