Medium access control is a vital mechanism in broadcast wireless transmission due to the need to allocate bandwidth among multiple users in an equitable manner while arbitrating possible contention that may arise. Multiple access protocols have been developed for almost 60 years for this purpose, starting with the invention and subsequent implementation of the legendary ALOHA random access protocol in 1968. A variety of wireless systems have since deployed these protocols, including terrestrial packet radio and satellite networks in the 1970s, wireless local area networks in the 1980s, wireless personal area networks in the 1990s, high-speed mobile cellular networks in the 2000s, and currently low-orbit satellite networks. Each of these networks uses a different approach, ranging from random access to contention-free protocols, depending on the span of the network, the number of users supported, and the traffic demands. Most of these protocols are converging toward an adaptive reservation system that unifies random access for gaining initial entry into the network and fixed bandwidth assignment for large data transfer. This book describes the design and analysis of medium access control protocols, as well as the efficient dimensioning of user density and bandwidth resources in wireless networks, including practical insights into the protocols used in Bluetooth, Wi-Fi, 5G, and Starlink satellites. The protocols in many of these local-area and wide-area systems aim to optimize their performance when supporting non real-time data and streaming multimedia traffic. As you will discover, many medium access control protocols underpinning modern-day wireless networks are based on creative ideas that have been developed several decades ago. They are also becoming more complex and challenging, ranging from deployments involving a single central controller to the coordination of multiple controllers, and from stationary networks to high-speed low orbit satellites. With emerging standards such as Wi-Fi 8 and 6G prioritizing higher user density with dynamic traffic load management over raw data rate improvement, the role of multiple access protocols will assume greater importance in the future.

The revolutionary Starlink low-orbit satellite system offers ubiquity and immediate broadband internet access for both fixed and mobile users to virtually every corner of the Earth. The system has effectively transcended beyond traditional wireline and terrestrial wireless access. This backbone of global connectivity is the final endgame to outdoor mobile communications and ubiquitous broadband internet access. A powerful advantage of the Starlink service is its portability, which is not possible with fixed wireless access or any wire medium. Driven by advanced solar power technologies and reusable rockets that can be refueled, the service is the game changer for pervasive broadband and mobile communications. Finally, there is an effective solution to bridge the digital divide and unleash the mobile traveler. The service offers up to 400+ Mbit/s data rates supplemented by Wi-Fi for connectivity to multiple user devices, but experiences less downtime than cable. Because the speed of light in an optical fiber or cable is only about two-thirds of its speed in a vacuum, intersatellite communications in Starlink is faster than any terrestrial ground system. Additionally, the Starlink system is easier to launch, maintain, and upgrade than any terrestrial system, with newer satellites to be located even closer to the earth to guarantee network latencies below 1/50th of a second to support the most time-sensitive applications like video gaming and self-driving cars. This concise book presents a clear overview of the Starlink low-orbit system components, the Starlink constellation and architecture, the Starlink satellite design, congestion control, and performance, the Starlink signal propagation delay, orbital speed and Doppler spread, and the Starlink bandwidth scheduling and spot beams.

Radio frequency (RF) system design forms the basis of wireless communications. This book provides an overview of the principles of RF system design, including the use of antennas and propagation models. It describes a classification of RF systems and then covers the basic functions of antennas, including the near and far fields, antenna gain, directivity, and radiation characteristics. Important RF propagation mechanisms and transmission modes are reviewed, such as the curvature of the RF beam and maximum RF range, surface (ground) wave, space wave, sky wave (ionospheric propagation), scatter propagation, and earth-space propagation. RF propagation impairments are described, including how signal fading, interference, and noise will impact the threshold received power. Transmitter issues are also covered. The models governing free-space propagation, outdoor propagation models, and smoothness criteria are studied, together with link budget and receiving antenna electric field calculations. The material is a result of a short course that was prepared for Qualcomm engineers and has been meticulously crafted to maximize clarity and accelerate learning.

The society of the future is likely to be shaped by a combination of human skills such as creativity, teamwork, and leadership coupled with AI’s data processing, pattern recognition, content creation, and predictive analytics. Chatbots have already replaced hundreds of thousands of non-physical jobs but they are essentially knowledge databases coupled with limited wisdom, trained using text-prompted datasets. The utility of AI is magnified significantly with human-like vision and physical action because a picture does speak a thousand words. The ability to see and analyze has revolutionize how state-of-the-art AI systems are designed and optimized, and has spawned the ultimate engineering masterpiece―humanoids. In this new era, humanoids will dominate many physical jobs. Humanoids are projected to be smarter than humans by 2027 and all of humanity by 2035, helping to bridge the human talent shortage caused by declining birth rates in the world population. More importantly, the humanoid is a personal concierge every young or old adult would like to have. An adaptive or autonomous system can be hard-coded to follow fixed steps and hence, does not qualify as an AI system. A true AI system is not only conscious of its environment but capable of learning from it with few or no human instructions, making the system unique and different from other systems, much like a talented child being nurtured in its own home or in the neighborhood school. This concise book uncovers many insights into the progress of AI technology and the key principles underpinning modern AI systems. Additionally, it is jam-packed with interesting ideas and applications that both novice and expert can harness in a short space of time.

The central processing unit (CPU) handles all the tasks required for all software on the computer or server to run correctly. A graphics processing unit (GPU), on the other hand, supports the CPU to perform concurrent calculations. A GPU can complete simple and repetitive tasks much faster because it can break the task down into smaller components and finish them in parallel. These cores were initially designed to process images, video game computer graphics, and visual data. General-purpose GPUs (GPGPUs) were adopted to enhance other computational processes, such as transformers and deep learning. More recently, AI is driving GPU tensor cores that achieve significantly higher throughput compared to traditional cores. This book provides a comprehensive overview of GPGPU internals, including its memory structure and optimization, the operation of tensor cores, and the current state-of-the art technology. It contains programming tips in using the NVIDIA CUDA parallel computing platform that allows software developers to use GPGPUs for specific applications. In addition to key examples involving scientific problems, neural networks, image processing, and video coding, the book also covers the graphics pipeline and steps to construct a scene, pipelining of GPU and CPU processes, as well as practical techniques in parallelizing an implementation.
