Low-latency Imaging and Inference from LoRa-enabled CubeSats
Akshay Gadre, Swarun Kumar, Zachary Manchester
Recent years have seen the rapid deployment of low-cost CubeSats in low-Earth orbit, primarily for research, education, and Earth observation. The vast majority of these CubeSats e…
High Resolution Point Clouds from mmWave Radar
Akarsh Prabhakara, Tao Jin, Arnav Das +6
This paper explores a machine learning approach for generating high resolution point clouds from a single-chip mmWave radar. Unlike lidar and vision-based systems, mmWave radar can…
Peekaboo: A Hub-Based Approach to Enable Transparency in Data Processing within Smart Homes (Extended Technical Report)
Haojian Jin, Gram Liu, David Hwang +3
We present Peekaboo, a new privacy-sensitive architecture for smart homes that leverages an in-home hub to pre-process and minimize outgoing data in a structured and enforceable ma…
Sensor as a Company: On Self-Sustaining IoT Commons
Haojian Jin, Swarun Kumar, Jason I. Hong
Beyond the "smart home" and "smart enterprise", the Internet of Things (IoT) revolution is creating "smart communities", where shared IoT devices collectively benefit a large numbe…
Toolbox Release: A WiFi-Based Relative Bearing Sensor for Robotics
Ninad Jadhav, Weiying Wang, Diana Zhang +2
This paper presents the WiFi-Sensor-for-Robotics (WSR) toolbox, an open source C++ framework. It enables robots in a team to obtain relative bearing to each other, even in non-line…
A Hybrid mmWave and Camera System for Long-Range Depth Imaging
Akarsh Prabhakara, Diana Zhang, Chao Li +4
mmWave radars offer excellent depth resolution even at very long ranges owing to their high bandwidth. But their angular resolution is at least an order-of-magnitude worse than cam…
A wireless signal-based sensing framework for robotics
Ninad Jadhav, Weiying Wang, Diana Zhang +3
In this paper we develop the analytical framework for a novel Wireless signal-based Sensing capability for Robotics (WSR) by leveraging robots' mobility. It allows robots to primar…
You foot the bill! Attacking NFC with passive relays
Yuyi Sun, Swarun Kumar, Shibo He +2
Imagine when you line up in a store, the person in front of you can make you pay her bill by using a passive wearable device that forces a scan of your credit card without your awa…
Sub-Nanosecond Time of Flight on Commercial Wi-Fi Cards
Deepak Vasisht, Swarun Kumar, Dina Katabi
Time-of-flight, i.e., the time incurred by a signal to travel from transmitter to receiver, is perhaps the most intuitive way to measure distances using wireless signals. It is use…
