Overview

Phased array signal processing has long been employed outdoors in radar, underwater in sonar, and underground in seismic monitoring. But it has only recently made inroads indoors in the context of WiFi networks, where it must cope with strong multipath reflections, packetized data transmissions, and commodity hardware. I will begin by describing two systems my students and I have worked on: ArrayTrack (published at USENIX NSDI 2013), one of the first fine-grained indoor location systems, and SecureArray (published at ACM MobiCom 2013), one of the most effective physical-layer based security mechanisms for WiFi networks.

Kyle Jamieson is a Senior Lecturer (tenure-track Assoc. Prof.) in the Department of Computer Science at University College London, and Principal Investigator on the European Research Council-funded CHAOSNETS and SmartTap projects. His research interests are in building real-world wirelessly networked systems that cut across the boundary of digital communications and networking. He has published well-cited works including the ArrayTrack indoor location system (NSDI ’13), the Collection Tree Protocol (SenSys ’09), and the SoftRate wireless bit rate adaptation protocol (SIGCOMM ’09). He serves on program committees including ACM MobiCom, USENIX NSDI, and ACM SIGCOMM. He received the PhD in Computer Science in 2008 from the Massachusetts Institute of Technology.
