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.
