5G Mobile Communications

Saad Z. Asif has been associated with the field of telecommunication for more than 20 years. He gained experience through working with three of the top-tier telecommunication operators—Sprint (US), Jazz (Veon), and Telenor Pakistan, and also through the Ministry of Information Technology and Telecommunication, Pakistan, which is a public policy-making institute. Asif is a strategic thinker, researcher, and telecommunications policy expert. He has been at the forefront of technology research and standardization and in providing strategic guidance throughout his career. He has led one of the first teams across the globe to evaluate state-of-the-art technologies such as 3G, 4G, Smart Antennas, e-band microwave radios, dense wavelength division multiplexing (DWDM), and many more. He played a key role in designing Sprint’s wireless high-speed data strategy, Jazz’s Broadband strategy, and Telenor’s Pakistan’s 3G and Transmission Network strategies. He is one of the main authors of GSMA’s (Global System for Mobile Association) award winning Pakistan’s National Telecommunications Policy 2015. He was also one of the key players in the successful execution of two frequency spectrum auctions that generated more than US$700 million for the national exchequer. He was also instrumental in defending the country’s scarce resource (frequency spectrum) at the World Radiocommunication Conference 2015. He has produced a Policy Directive on 5G and developed Pakistan’s first 3-year rolling Frequency Spectrum strategy and Cyber Governance policy. Asif has written two books and numerous peer-reviewed technical papers on telecommunications. He has been granted five patents as a co-patentee by the United States Patent & Trade Office. He has also been listed as a scientist in the Productive Scientists of Pakistan directory since 2009. He has also been a senior member of the IEEE (Institute of Electrical and Electronics Engineers) since 2004. He also served on the board of directors of Pakistan’s National Radio & Telecommunication Corporation. Asif earned a BS and an MS in electrical engineering from Oklahoma State University in 1996 and 1997, respectively. He also earned an MS in engineering management from the University of Kansas in 2001.

"This is a comprehensive reference on mobile communications technology and market issues. The book is well-written and concise, and does not require specialized training to digest the key messages. It provides useful background on the origins of mobile telephony, and goes into depth on all key technical aspects of 5G which continue to shape market developments in 2020. I refer to this book frequently during the course of my research and writing on telecom network infrastructure topics. This is an excellent resource for those wishing to understand 5G communications."Matt Walker, Chief Analyst, MTN Consulting LLC"This [book is] a perfect resource for both beginners and experts."~Dr. Sabit Ekin, Oklahoma State University"This book will be a good addition to knowledge, because its provides the basic concepts of 5G communication and also discuss all the underlying technologies used for communication."~Ghulam M. Chaudhry, Ph.D., University of Missouri-Kansas City"The main strength, in my view, is that the Author has spent several years in the field, working for Telecom Operators and Policy making bodies. His practical hands-on experience and real-life problems that he faced and how he solved them adds real value and is the main strength of this book.I like the approach taken by the Author to gradually build the background, present the big picture first before divulging in to details. For example, he starts with with concept of basic and applied research and how its applicable in telecommunications; the need of standardization and the role standardization bodies; product development; end-to-end architecture of a mobile network; and key challenges as well as best practices in telecom industry.….it is a very unique book in which the Author has not only covered almost all the technical aspects of 5G Technology but also walked the reader through the journey which lead up to this development. He has provided the big picture of why and how technological developments materialize. From conception of idea to commercial deployment of technologies, the Author has beautifully captured the phases involved."~Imad Memon, Pakistan Telecommunications Authority
