'IIT-BHU develops tech for long-range communication using drones'
VARANASI, May 24 -- The Indian Institute of Technology-BHU Varanasi, has developed a system that allows the sharing of images and messages without internet connectivity and with virtually infinite range. The innovation, which combines custom-built devices with drone-based relays, offers a new direction in resilient, long-range communication.
Senior office-bearer of the press and Publicity Cell, IIT-BHU Utkarsh said that led by Dr Hari Prabhat Gupta, associate professor, department of Computer Science and Engineering, the research team has created a dedicated self-sustaining transmission mechanism (SSTM) that uses autonomous drones to carry and forward data across large distances - even in areas without any communication infrastructure. The technique enables real-time sharing of images and text, allowing communication to continue in remote, obstructed or high-interference regions. The system has been tested in challenging conditions simulating signal-blocked environments and inaccessible zones.
According to Dr Gupta, the drones form a dynamic mesh network capable of adapting to terrain and movement, making it ideal for use in defense applications, border surveillance, territorial field communication, and disaster response.
"The system doesn't rely on conventional internet or satellite links," he said. "It's an entirely new class of resilient communication where even blackhole-like zones can be bridged."...
