And the rest is history... A historical perspective of Wi-Fi
Cisco Systems was instrumental in launching Wi-Fi. The tech giant printed 18,000 copies of my first book and produced a simple wireless CD to promote its first wireless product―the Aironet Wi-Fi product. With their strong Ethernet customer base, the bold move helped jumpstart 802.11b in 1999 when the original 802.11 standard (ratified in 1997) was a failure and the technology was facing intense competition from 3G mobile cellular, riding on the global success of 2G. Additionally, the Wi-Fi Alliance was at the crossroads with weak support from a handful of small vendors, rebranding itself from Wireless Ethernet Compatibility Alliance (WECA). It turned out that Wi-Fi blossomed and 3G was not a success. A decade later, the Wi-Max Forum attempted to promote the 802.16 standard but failed. 4G-LTE became an instant success instead, driven by the demand for short-form video streaming in social apps. Wi-Fi had grown to a global phenomenon by then, penetrating consumer electronics in addition to local area computer networks in enterprises and homes.

The internet has become the mainstream media platform for the distribution of live and on-demand video entertainment, and has opened up new ways for discovering, sharing, and consuming TV content anywhere, anytime, and on any device. Next-generation video coders and decoders can be deployed quickly, allowing online providers to stay ahead of the pack when rolling out 4K ultra high-definition (UHD) services and premium content. However, video delivery platforms perform differently in terms of the quality and smoothness of the video playback. In addition, high-quality videos such as UHD videos sometimes look like HD videos after compression. This all-in-one book addresses the end-to-end video chain, from coding to streaming to playback. It also covers the foundational principles of color science, human visual system, and high dynamic range (HDR) technologies. With over 260 illustrative figures and charts, 60 tables, 150 equations, and packed with numeric examples, this indispensable guide is designed for any video developer or engineer building advanced video coding and streaming systems from ground up.

The mobile cellular standard beyond 4G-LTE is 5G. If Wi-Fi is wireless Ethernet, then 5G is wireless Fiber. 5G promises to deliver the Internet of Everything by empowering smart cities and homes, industry automation, self-driving cars, augmented reality, and work, gaming, and entertainment in the cloud. While 4G-LTE is driven by millions of multimedia personal devices that require high-speed internet connectivity, 5G supports an even greater number of applications and services, expanding beyond person-to-person communications. This new kind of wireless network connects not only users but also machines, devices, and objects. By using both shared and millimeter wave spectrum in a flexible and efficient manner, network performance is enhanced in terms of better link quality and reliability, higher connection speeds and density, and lower latency. Many operators around the globe have rolled out fixed, mobile, and private 5G services, with over 5 billion mobile subscribers and 15 billion Internet of Things (IoT) connections.

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.
