He joined Siemens AG, in 1991. He was involved in several EU funded projects and ETSI standardization groups on UMTS and systems beyond 3G. In December 1996 he became project manager of the European ACTS FRAMES Project until the project finished in August 1999. This project developed the basic concepts of the UMTS radio interface. Since April 2007 he has been with Nokia Siemens Networks GmbH & Co. KG, Germany, where he is Head of Research Alliances. He was the coordinator of the WINNER Project in Framework Program 6 of the European Commission, and the Eureka Celtic project WINNER+. Dr. Mohr is an IEEE Senior Member. He is a co-author of the books Third Generation Mobile Communication Systems and Radio Technologies and Concepts for IMT-Advanced.

"The book is up with the latest thinking and standards, and as such provides a particularly useful coverage of the way in which cellular telecommunications is moving. It would be a valuable addition to the library of any individual or company that is serious about keeping up with the latest LTE technology." (Radio-Electronics.com, 1 January 2012)
