Khalifa University Digital Future Institute develops world’s first breakthrough radio-frequency AI language model ‘RF-GPT’
RF-GPT Introduces a New Type of AI System That Can Analyze Radio Signals and Explain What it Sees Using Plain Language
Abu Dhabi, UAE – Khalifa University of Science and Technology’s Digital Future Institute today announced the launch of ‘RF-GPT’, a first-of-its-kind radio-frequency AI language model capable of interpreting wireless signals. This innovation overcomes a major limitation in telecom AI, where language models typically operate only on text and structured network data.
Translating the Spectrum into Plain English
RF-GPT works by turning radio signals into visual patterns that artificial intelligence can understand. Once converted, AI systems can analyze those patterns and answer questions about what is happening in the wireless spectrum using plain language.
The system showed consistent performance improvements in radio frequency spectrogram tasks, outperforming existing baseline models by up to 75.4%. In a breakthrough achievement, RF-GPT correctly counted the number of signals in a spectrogram ~98% of the time—a feat that general-purpose AI models almost never achieve.
Setting the Stage for 6G and AI-Native Networks
The foundation model directly contributes to the UAE National Artificial Intelligence Strategy, laying the groundwork for more autonomous and intelligent wireless networks.
The project was developed by Khalifa University researchers led by Professor Merouane Debbah, Senior Director of the Digital Future Institute. The research team includes Post Doctoral Fellows Hang Zou, Yu Tian, Research Scientists Dr. Lina Bariah from Khalifa University, Dr. Samson Lasaulce from Université de Lorraine, as well as Dr. Chongwen Huang and PhD student Bohao Wang from Zhejiang University.
“The launch of ‘RF-GPT’ reflects Khalifa University’s long-term focus on innovation in digital infrastructure to advance AI integration across strategic sectors, and next-generation connectivity research, aligned with national priorities,” said Professor Ahmed Al Durrah, Associate Provost for Research, Khalifa University. “Initiatives such as this model contribute to the UAE’s fast-growing human capital and research capabilities necessary to support the UAE’s evolving digital ecosystem.”
Bridging the Gap Between Telecom and AI
Professor Merouane Debbah summarized the significance of the invention: “RF-GPT represents a turning point for spectrum intelligence, moving from isolated, task-specific radio frequency pipelines toward a unified RF-language interface. We gave a language model its first glimpse of the electromagnetic spectrum and the view is already remarkable. Imagine what it will see next.”
By making the physical layer "quarriable" in natural language, RF-GPT opens the door to AI-native radio systems where RF perception can directly support network optimization and policy decisions, a crucial step toward future AI-native 6G networks.
The model was trained using approximately 625,000 computer-generated radio signal examples. It is designed for telecom operators, network engineering teams, and spectrum authorities to support increasingly complex wireless environments. Its core capabilities include:
- Identifying signal types
- Detecting overlapping transmissions
- Recognizing wireless standards
- Estimating device usage in Wi-Fi networks
- Extracting data from 5G signals
