The Urban Wireless Sensing Lab (UWSL) based at University College London (UCL) is focussed on sensor technologies that have applications in a range of urban environments ranging from security and e-healthcare, to IoT and transportation. Our research is centred around the design, development and testing of novel wireless-based systems and associated signal processing techniques for human activity recognition, through-the-wall detection, joint communications and sensing, contextual awareness and human-computer interaction.
