Pioneering Relative Localization for Enhanced Communication in a Radio-Acoustical Virtual Environment (RAVE)

Radio-acoustical virtual environment (RAVE) is a new concept where radio signals are received by workers within a specific range based on their vocal effort and background noise level. In this context, we propose an innovative radio-frequency (RF) system for real-time localization and positioning. The key feature of this solution is its ability to simultaneously allocate time slots for communication and additional slots for ranging measurements. This method incorporates the direction-of-arrival (DOA) and orientation of radios within a dynamic mesh network, distinguishing it from other state-of-the-art techniques. The RAVE’s capability for dynamic resource allocation and adaptive communication strategies enhances performance and efficiently utilizes network resources in challenging industrial environments.
