IIT Madras Unveils Real-Time Indoor Mapping Tech for Smart Navigation
In a major innovation for smart navigation, IIT Madras has developed an advanced real-time indoor mapping technology aimed at transforming navigation within complex buildings. Designed to assist users in large indoor spaces such as hospitals, malls, and airports, the system uses LiFi-based communication for precise real-time tracking. The project also holds promise for emergency services, offering faster routes in crisis scenarios. This initiative reinforces IIT Madras' leadership in cutting-edge research with practical urban applications.

IIT Madras has made a significant leap in smart navigation with its newly developed real-time indoor mapping technology. Unlike GPS, which is ineffective indoors, this new system enables precise, room-level navigation within large indoor structures. The innovation stands to benefit sectors ranging from healthcare and retail to emergency response, marking a turning point in how people and services move through indoor environments.
How the Indoor Mapping System Works
The system relies on LiFi (Light Fidelity) technology, which uses LED light signals for data transfer and communication.
It allows real-time user localization by detecting signals from indoor infrastructure like ceiling-mounted lights.
Users can access location details through smartphones or wearable devices for seamless navigation.
The innovation eliminates the need for GPS indoors, offering far more accuracy and stability.
Applications Across Multiple Sectors
In hospitals, the technology helps patients and staff navigate to specific departments or emergency rooms without confusion.
In airports and malls, it can provide personalized routing and assist in locating gates, stores, or services quickly.
For emergency responders, it can guide personnel through unfamiliar buildings with the shortest paths in real time.
Future integrations may include AI-based alerts for congestion and alternative route suggestions.
IIT Madras Leads in Research and Innovation
This technology reflects the institution’s ongoing efforts to merge academic research with real-world solutions.
The indoor mapping project is part of IIT Madras' broader smart city research initiative.
Collaborative efforts are underway with industries to scale and deploy the solution across India.
The innovation aligns with the national vision for digital and accessible public infrastructure.
Conclusion
With the launch of this indoor mapping technology, IIT Madras has set the stage for the future of smart navigation. This breakthrough will redefine indoor mobility and accessibility in India’s growing urban spaces.
