Indoor radio positioning systems have attracted a lot of attention from various sectors of our life, which include such as the health care, homeland security, tourism, and location based services. Many different technologies and systems have been proposed and developed. In this talk we will compare them to identify their advantages and disadvantages. The challenges and future directions will also be discussed and addressed.
