In the epoch of automation, the ability to navigate devices and persons has become increasingly important for rising number of applications. With the emergence of GPS (Global Positioning System) the outdoor positioning has become outstanding but many applications require coherent positioning capabilities in all the environments. In view of this, indoor positioning has become a focus of research and development in the past decade. The number of relevant requirement parameters is large like accuracy, integrity, coverage, latency, update rate, availability, costs, robustness, infrastructure, privacy. Along with the diverse number of technologies available, making it further complex to match a suitable technology with an application.
