|Abstract:||:||Phased array signal processing has long been employed outdoors in
radar, underwater in sonar, and underground in seismic monitoring.
Today, it has the potential to revolutionize the Internet of Things
(IoT) by giving us the ability to track every one of the billions of
IoT devices indoors, and meet their exploding bandwidth requirements.
But to make the shift to indoor wireless networks, it must cope with
strong multipath radio reflections, packetized data transmissions, and
commodity hardware platforms. In this talk I will describe two
relevant systems through the lens of system-building and
experimentation. First, I will describe an indoor location system
that uses solely the existing Wi-Fi infrastructure to achieve a median
location accuracy of 23 centimeters, and sub-second response time,
allowing Wi-Fi-enabled devices to be tracked in real-time. Next, I
will present a MIMO-based Sphere Decoder system that leverages novel
search algorithms and geometric reasoning to increase wireless
throughput, the first of its kind that scales to 256-QAM constellation
densities with computational demands that are practically realizable
in current ASIC hardware. Finally, I will conclude with a vision of
how these techniques will support exciting IoT applications such as
video analytics over billions of indoor wireless cameras.
