Smarter SOS: Generative AI at the Edge for Emergency Communication over Satellite Links
Description of the company
NXP Semiconductors is a global leader in secure connectivity, embedded processing, and edge-computing solutions. The CTO System Innovation Competence Center develops forward-looking concepts for the next generation of connected systems. With a focus on AI-Enabled Future Connectivity, the center explores innovative hardware and software solutions that enable the use of artificial intelligence in safety-critical applications such as emergency communication.
NXP technologies play a key role in industrial, medical, and automotive domains, where reliable and efficient communication systems are essential. By combining hardware expertise with advanced AI capabilities, NXP drives innovation in areas ranging from connected cars and intelligent healthcare devices to resilient industrial infrastructure.
Situation
Modern emergency systems, such as the SOS service on smartphones or the BMW eCall demonstrator over satellite, allow emergency calls to be transmitted via satellite links. However, due to the severe bandwidth limitations of Non-Terrestrial Networks (NTN), only minimal data such as GPS coordinates or a standardized SOS activation message can be transmitted. Rich, semantic communication (e.g., speech, contextual details, medical information) is currently not possible.
So far, generative AI models have mainly been deployed in the cloud, which is not practical in emergency situations without stable connectivity. With modern edge hardware platforms (e.g., NXP i.MX95), the possibility arises to bring Generative AI to the Edge. In this setup, classical Speech-to-Text (STT) and Text-to-Speech (TTS) systems act as enabling technologies to convert spoken language into text and back. The real added value comes from Generative AI models, which can compress, condense, and reconstruct the semantic content of messages, enabling meaningful communication even with minimal bandwidth.
Problem
Existing SOS systems over satellite currently allow only very limited information transfer.
This creates a critical gap between technical feasibility (satellite connectivity, cloud AI) and the practical need for reliable, real-time AI at the edge in emergency scenarios.
Aims of the project
The project aims to design and prototype an AI-assisted emergency communication system that enables meaningful, reliable, and context-rich communication over satellite links, even with minimal data rates.
Sub-goals:
Scopes
Emergency situations can occur in very different environments – often in places without terrestrial mobile network coverage. Relevant scenarios include:
Industrial operations: accidents on offshore platforms, in mines, or at remote construction sites.
Emergency situations can occur in very different environments – often in places without terrestrial mobile network coverage. Relevant scenarios include:
In such cases, Generative AI at the Edge can be critical, ensuring that precise and semantically relevant information reaches emergency centers despite extremely low bandwidth. The goal is to enable higher survival chances, faster response times, and more efficient use of rescue resources.
The project focuses on the conceptual design and prototypical implementation of an AI-assisted emergency communication system over satellite links with Generative AI at the Edge.
