Mobile position aware systems combined with modern wireless technologies are getting more and more important. When developing systems of this kind, problems in various fields of information and communication technology need to be solved. The workshop shall give an overview of state-of-the art approaches and systems. As many technologies are available to deal with the variety of applications, we would like to continue to cover ultra-wideband technology as it is becoming of great importance in the area of positioning, navigation and communication.

The 4th Workshop on Positioning, Navigation and Communication 2007 (WPNC'07) took place at the Information Technology Laboratory of the Leibniz University of Hannover, Germany, March 22, 2007, right after CeBIT'07.

IEEE VTS co-sponsors the WPNC. The workshop proceedings are published in the IEEE Xplore database.
