Satellite Connectivity for Internet of Things
Satellite networks offer one-click connectivity for sensors in remote areas, enabling farmers and industries to access data globally. By connecting sensors directly to satellites, data is seamlessly transmitted to ground stations for easy internet connection. Democratizing space connectivity is emphasized by creating affordable and smaller satellites for universal access.
Research Methodology and Innovation
The research focuses on launching satellites to address real-world challenges hands-on, avoiding assumptions and learning from existing industry practices. By launching a satellite and experiencing industry issues firsthand, innovative solutions are developed to enhance satellite connectivity and make it more accessible globally.
Spectrum Management and Coexistence
To address spectrum shortage and prevent packet collisions in satellite communication, a unique approach using Doppler signatures is employed. By recognizing satellite frequency signatures, devices can differentiate signals and communicate effectively without interference. The goal is to ensure reliable connectivity for various industries and individuals worldwide.
Tusher Chakraborty talks about the paper “Spectrumize: Spectrum-efficient Satellite Networks for the Internet of Things,” including a method for supporting communication between a large IoT-satellite constellation and devices on Earth within a limited spectrum.
