Location of Radio Sources

Many services in future mobile radio systems like E-911, location sensitive billing, cellular system design, resource management, fleet management and intelligent transportation systems need information on the location of the mobile terminals. Consequently, an important requirement for the physical layer of future mobile radio systems is the ability to deliver precise location information. State of the art solutions based on the measurement of channel attenuation or access delay cannot fulfil the stringent performance requirements of future applications especially in typical mobile radio scenarios with multipath propagation. Even satellite navigation systems like GPS do not fulfil the requirements as they do not work inside of buildings. The Research Group for Radio Communications investigates novel database based location techniques. Furthermore, hybrid location techniques, which combine several of the mentioned techniques, are taken into consideration.
