And the rest is history... A historical perspective of Wi-Fi
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, Wi-Max (802.16) tried to promote itself but ended in failure. 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.

Wi-Fi data rates and spectral efficiencies have continued to improve over the past two decades. By adding multi-user multi-link transmission to multi-antenna and multi-carrier capabilities, next-generation Wi-Fi will be able to connect to an unprecedented number of personal devices and “things”, expanding beyond user-to-user communications. This book describes the foundational principles of Wi-Fi, including the latest technologies and applications. It is the first book to discuss the technical details of the new 802.11be amendment and provide a comparative assessment of 802.11ax and 802.11be. The book also presents practical issues in Wi-Fi performance optimization, and key physical and access layer mechanisms. Among the topics covered include OFDM, OFDMA, multi-user multi-antenna multi-link technologies, beamforming protocols, dynamic channel switching, and operating range versus rate tradeoffs. With over 200 illustrative figures and tables, this indispensable guide is designed for any wireless engineer building advanced Wi-Fi systems from ground up.

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. 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 IoT connections. This book describes the foundational principles, technologies, and use cases of 5G, including its evolution from 4G-LTE, LTE-Advanced, LTE-Advanced Pro to 5G Release 15, 16, 17, 5G-Advanced (Release 18), and ultimately 6G. With over 250 illustrative figures and tables, this indispensable guide is designed for any wireless engineer building advanced cellular systems from ground up.
