About this project

Design and Implementation of a Visible-Light Communication Indoor Positioning System for Indian Smart Buildings

Objective: To engineer and validate a visible-light communication based indoor positioning system enabling accurate location tracking within Indian commercial and institutional spaces.

Indoor positioning is a critical requirement in Indian commercial buildings, hospitals, airports, and shopping malls, where traditional GPS fails due to signal attenuation inside structures. This impacts asset tracking, navigation, and safety, especially in large, complex environments.

The proposed solution leverages visible-light communication (VLC) using LED luminaires as transmitters and photodiode-based receivers to localize users or assets with sub-meter accuracy. The project involves designing a hardware prototype, deploying multiple VLC nodes, and developing signal processing algorithms tailored to Indian indoor conditions and lighting standards.

Key features include real-time location estimation, robust operation under varying ambient light, a working model demonstrating live tracking on a mapped floorplan, and performance evaluation against benchmarks. Deliverables are a fabricated prototype, system software, test results, and a technical paper, all demonstrated before an examiner panel.

Industry impact includes scalable integration into smart building management, improved asset utilization, enhanced safety, and potential for expansion into IoT-based indoor navigation in Indian public spaces. The solution addresses local cost constraints and standards for rapid adoption.
