The Architectural and Technological Revolution of 5G

The book discusses the evolution of cellular technology, then focusing in on 5G and its architecture and what it means for current engineers. The book first focuses on 4G and how it changed the industry, allowing people to communicate by connecting devices to the internet. The authors detail the emergence of services and applications that have revolutionized communication and continue to impact the daily habits of majority of the world's population. The authors endeavor to tell this story by showing the path taken until the arrival of 5G, detailing how technological and architectural progress evolved in all these years. It is a technical book, but the authors take care to explain in detail each aspect related to technology in order to allow everyone interested in the subject to delve into this important topic.

• Presents a comprehensive explanation about 4G and 5G architecture, modulation and protocols;
• Includes a thorough explanation of modern antennas technology and O-RAN;
• Relevant to technology professionals and students interested in 5G, but with little background in telecommunications;

José Luiz Frauendorf was born in São Paulo, Brazil. He got his degree in electronic engineer from the Institute Mauá of Technology. He started his professional career at AEG Telefunken, in Backnang, Germany, where he worked on the development of telecommunication systems, including coaxial cable systems and microwaves. Later, he was transferred to Brazil with the responsibility of implementing at the local subsidiary the manufacturing of public telephony systems which included voice channels multiplexing systems, microwave systems, and monitoring and supervision systems for telecommunications stations. With the acquisition by Grupo Docas de Santos of ELEBRA Eletrônica Brasileira, he was invited to take over the product development area of ELEBRA Informática. Subsequently, he held the position of industrial and technical director of ELEBRA Computers until its acquisition by Digital Equipment Corporation, when he became the plant manager of the Brazilian subsidiary. He participated in TVA—Grupo ABRIL Television System, having been its general director of operations. After that, he became general director of NEOTEC, an association created to develop technologies to provide multimedia services using the 2.5GHz spectrum.

Frauendorf coordinated tests of systems providing broadband services using WCDMA and OFDM modulation systems, and later WiMAX technology, in several Brazilian cities. In 2010, he participated in the turnaround of a family company, from which he withdrew when it was sold in 2014. After his experience in the polymer segment, he developed a new technology for electrically insulating gloves using synthetic materials. His invention was patented in several countries. Since 2020, he has been dedicating himself in writing books and disseminating news in the areas of new technologies.

Érica Almeida de Souza got her degree in telecommunications engineering and postgraduate from INATEL (National Institute of Telecommunications). She participated in several training courses in telephony and data transmission at Huawei, both in China and in Brazil. She started her professional career at the former CFLCL, now Energisa. She also worked at Panasonic do Brasil and later at Huawei, where she had the opportunity to promote training courses in Brazil and Latin America. She is currently caring out advance training courses at IWF Training and Consulting
