Enabling Efficient Coexistence of Low-Power Wide-Area Networks in the Sub-GHz Spectrum

This project between Dalhousie University and Paris-Saclay University focuses on improving how low-power wireless networks share the sub-GHz radio spectrum. These networks, including LoRaWAN, Wi-Fi HaLow, and Sigfox, are widely used in smart cities, agriculture, and environmental monitoring. However, when they operate in the same unlicensed frequency bands, interference can occur, reducing reliability and energy efficiency. This project will develop energy-efficient methods for detecting ongoing transmissions using lightweight artificial intelligence models and will introduce cooperative strategies that help networks share spectrum fairly and adaptively.
The collaboration includes a two-way research exchange. One PhD student from Dalhousie will visit Paris-Saclay for twelve weeks, and one PhD student from Paris-Saclay will spend twelve weeks at Dalhousie. Both students will benefit from joint supervision, complementary expertise, and international training opportunities. Research outputs, including simulation tools, experimental data, and prototype implementations, will be shared openly with academic and industrial communities. The project builds on ongoing connections with international research and industry partners and is expected to inform both technical practices and broader approaches to spectrum use. By promoting collaboration, openness, and adaptability, the project supports more sustainable and accessible wireless connectivity in Canada, France, and beyond.
