The past few years have seen a dramatic growth in wireless sensing systems, with millions of wirelessly connected sensors becoming first-class citizens of the Internet. The number of wireless sensing devices is expected to surpass 6.75 billion by 2017, more than the world's population as well as the combined market of smartphones, tablets, and PCs. However, its growth faces two pressing challenges: battery energy density and wireless radio power consumption. Battery energy density looms as a fundamental limiting factor due to slow improvements over the past several decades (3x over 22 years). Wireless radio power consumption is another key challenge because high-speed wireless communication is often far more expensive energy-wise than computation, storage and sensing. To make matters worse, wireless sensing devices are generating an increasing amount of data. These challenges raise a fundamental question --- how should we power and communicate with wireless sensing devices. More specifically, instead of using batteries, can we leverage other energy sources to reduce, if not eliminate, the dependence on batteries? Similarly, instead of optimizing existing wireless radios, can we fundamentally change how radios transmit wireless signals to achieve lower power consumption? A promising technique to address these questions is backscatter --- a primitive that enables RF energy harvesting and ultra-low-power wireless communication. Backscatter has the potential to reduce dependence on batteries because it can obtain energy by rectifying the wireless signals transmitted by a backscatter reader. Backscatter can also work by reflecting existing wireless signals (WiFi, BLE) when these are available nearby. Because signal reflection only consumes uWs of power, backscatter can enable ultra-low-power wireless communication. However, the use of backscatter for communicating with wireless sensing devices presents several challenges. First, decreasing RF power across distance limits the operational range of micro-powered backscatter devices. This raises the question of how to maintain a communication link with a backscatter device despite tiny amount of harvested power. Second, even though the backscatter RF front-end is extremely power-efficient, the computational and sensing overhead on backscatter sensors limit its ability to operate with a few micro-Watts of power. Such overhead is a negligible factor of overall power consumption for platforms where radio power consumption is high (e.g. WiFi or Bluetooth based devices). However, it becomes the bottleneck for backscatter based platforms. Third, backscatter readers are not currently deployed in existing indoor environments to provide a continuous carrier for carrying backscattered information. As a result, backscatter deployment is not yet widespread. This thesis addresses these challenges by making the following contributions. First, we design a network stack that enables continuous operation despite decreasing harvested power across distance by employing an OS abstraction --- task fragmentation. We show that such a network stack enables packet transfer even when the whole system is powered by a 3cmx3cm solar panel under natural indoor light condition. Second, we design a hardware architecture that minimizes the computational overhead of backscatter to enable over 1Mbps backscatter transmission while consuming less than 100uWs of power, a two order of magnitude improvement over the state-of-the-art. Finally, we design a system that can leverage both ambient WiFi and BLE signals for backscatter. Our empirical evaluation shows that we can backscatter 500bps data on top of a WiFi stream and 50kbps data on top of a Bluetooth stream when the backscatter device is 3m away from the commercial WiFi and Bluetooth receivers.

This is one of the first books on the emerging research topic of digital compensation of RF imperfections. The book presents a new multidisciplinary vision on the design of wireless communication systems. In this approach the imperfections of the RF front-ends are accepted and digital signal processing algorithms are designed to suppress their impact on system performance. The book focuses on multiple-antenna orthogonal frequency division multiplexing (MIMO OFDM).

This thesis explores how RF backscatter can serve as an indispensable tool for designing low-power sensor networks. Low-power techniques allow sensors to be deployed where there is insufficient power or communication infrastructure for traditional sensor nodes. RF backscatter communication consumes an order of magnitude less power than even Bluetooth Low Energy. This dissertation presents three projects that advanced the state-of-the-art in sensing systems that harness RF backscatter. The first two projects, FreeRider and BackCam, describe systems that can backscatter commodity WiFi signals. Instead of having to invest in special-purpose transceivers, we can harness WiFi radios that are already ubiquitous. FreeRider is a backscatter communication platform designed to operate on top of existing ISM-band networks, like 802.11 WiFi. BackCam~\cite{backcam} extends this work by adding a camera sensor to the tag and implementing an edge-based control system. Using RF backscatter makes communication cheap, which allows us to push image processing to the edge. The next project, RayTag, demonstrates how pairing backscatter tags with radars makes the target signal 100-10,000x stronger in amplitude compared to the strongest clutter signal. This allows for simultaneous detection and identification of multiple targets, which is useful for a variety of sensing applications. To demonstrate the potential of RayTag, I show that deploying backscatter tags underground can be used to accurately measure soil moisture. Though I focus on the evaluation of sensing soil moisture, RayTag is not a single-purpose sensing system. Rather, RayTag can be used to enhance a number of existing sensing tasks (e.g. localization) or enable entirely new applications. To that end, this thesis also presents detailed evaluations beyond underground contexts, as well as multiple examples of constructing link budgets. This dissertation further explores a renewable power source for underground backscatter tags. Many backscatter communication systems can harvest their operating power via RF, but this is not practical for underground systems because wet soil attenuates RF too much for harvesting circuits to operate. One potential source of energy are microbes in the soil. Microbial fuel cells (MFCs), sometimes also known as mud or soil batteries, accept electrons that are a byproduct of redox reactions catalyzed by electrogenic microbes naturally occurring in soil. This creates a potential difference across the cathode and anode, which provides a low-cost renewable source of power. In the future, this could allow underground backscatter tags to have an indefinite lifetime.

Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.
