The need for highly accurate position information is of great importance in many commercial public safety and military applications. With the integration of GPS into cell phones in conjunction with WiFi localization we are entering a new era of ubiquitous location-awareness. In the coming years we will see the emergence of high-definition location-awareness applications localization systems that operate in the harsh communication environments where GPS does not operate such as inside buildings and in caves still providing submeter localization accuracy which is not currently feasible with GPS. Reliable localization in such conditions is a key enabler for a wide variety of applications including logistics security tracking the localization of authorized persons in high-security areas medical applications the monitoring of patients search and rescue communications with fire fighters or natural disaster victims control of home appliances automotive safety and military systems as well as in the
