The broad prevalence of mobile communication devices opens new business opportunities, including very diverse location based services. The required determination of the position of the devices is a big technical challenge. While GPS is a system for outdoor areas, there is no generally accepted solution for indoor areas. This dissertation introduces a new method that is particularly useful for indoor areas and uses the time of flight of a wireless signal. A significant advantage of the work presented in this thesis is the high time resolution for the signal time of flight measurement through which a very accurate location is achieved using commercial-off-the-shelf hardware. In addition, novel algorithms for the processing of the measurements and for calculating the 2D/3D position as well as three example implementations on different base technologies for wireless communications are presented.
