The Architectural and Technological Revolution of 5G

Jose Luiz Navarro Frauendorf was born in Sao Paulo, Brazil. He got his degree in Electronic Engineer at the Institute Maua 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 transferred to Brazil with the responsibility of implementing at the local subsidiary the manufacturing equipment division for public telephony, 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 Eletronica Brasileira, he was invited to take over the product development area of ELEBRA Informatica. Subsequently, he held the position of Industrial & 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. 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. Erica Almeida 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.
