The Internet of Things (IoT) technology has been the heart of several technological advances in our day to day. This has been enabled by the seamless connectivity across several types of devices such as wearables, phones, and other sensors deployed across a smart home. Data-driven decision-making is pushing the bounds of connectivity. The scale of devices is increasing, and a higher communication range is desired. However, bulky batteries and power sources deter the deployment of IoT nodes. In this thesis, I categorize IoT nodes based on the desired communication range: short range up to hundreds of meters, long range up to tens of km, and very long range up to thousands of km. In each chapter of my thesis, I study each of these categories of nodes and propose solutions to achieve a higher communication range without requiring any additional power. I also demonstrate that our novel algorithms are able to accommodate a larger number of devices transmitting concurrently. I present the design and implementation of prototypes built using off-the-shelf (OTS) components. In Chapter Three, I present PACT, a passive battery-free tag with an active radio that communicates with the reader using a novel query-response model to reduce power consumption. Our tag achieves a communication range of 400m and allows for the co-existence of hundreds of tags. In Chapter Four, I present WiChronos, a novel data modulation algorithm that is inspired by optical communication systems. The payload modulated the time interval between two wireless symbols, the preamble and the postamble. Our tag, while coexisting with thousands of other tags, can transmit to a receiver located 4.2km away. In Chapter Five, I present SatConnect, a novel continent-scale IoT node that uses OSCAR satellites to achieve a communication range of thousands of km. Experiments to demonstrate a range of 1100km are being conducted.

The increasing demand for extremely high-data-rate communications has urged researchers to develop new communication systems. Currently, wireless transmission with more than one Giga-bits-per-second (Gbps) data rates is becoming essential due to increased connectivity between different portable and smart devices. To realize Gbps data rates, millimeter-wave (MMW) bands around 60 GHz is attractive due to the availability of large bandwidth of 9 GHz. Recent research work in the Gbps data rates around 60 GHz band has focused on short-range indoor applications, such as uncompressed video transfer, high-speed file transfer between electronic devices, and communication to and from kiosk. Many of these applications are limited to 10 m or less, because of the huge free space path loss and oxygen absorption for 60 GHz band MMW signal. This book introduces new knowledge and novel circuit techniques to design low-power MMW circuits and systems. It also focuses on unlocking the potential applications of the 60 GHz band for high-speed outdoor applications. The innovative design application significantly improves and enables high-data-rate low-cost communication links between two access points seamlessly. The 60 GHz transceiver system-on-chip provides an alternative solution to upgrade existing networks without introducing any building renovation or external network laying works.

Over the past two decades we have witnessed the increasing popularity of the internet of things. The vision of billions of connected objects, able to interact with their environment, is the key driver directing the development of future communication devices. Today, power consumption as well as the cost and size of radios remain some of the key obstacles towards fulfilling this vision. Ultra-Low Power FM-UWB Transceivers for IoT presents the latest developments in the field of low power wireless communication. It promotes the FM-UWB modulation scheme as a candidate for short range communication in different IoT scenarios. The FM-UWB has the potential to provide exactly what is missing today. This spread spectrum technique enables significant reduction in transceiver complexity, making it smaller, cheaper and more energy efficient than most alternative options. The book provides an overview of both circuit-level and architectural techniques used in low power radio design, with a comprehensive study of state-of-the-art examples. It summarizes key theoretical aspects of FM-UWB with a glimpse at potential future research directions. Finally, it gives an insight into a full FM-UWB transceiver design, from system level specifications down to transistor level design, demonstrating the modern power reduction circuit techniques. Ultra-Low Power FM-UWB Transceivers for IoT is a perfect text and reference for engineers working in RF IC design and wireless communication, as well as academic staff and graduate students engaged in low power communication systems research.
