The availability of position information plays an increasing role in wireless communications networks already today and will be an integral part of future systems. They inherently can offer the ability for stand-alone positioning especially in situations where conventional satellite based positioning systems such as GPS fail (e.g., indoor). In this framework, positioning information is an important enabler either for location and context-aware services or even to improve the communications system itself. The WHERE2 project is a successor of the WHERE project and addresses the combination of positioning and communications in order to exploit synergies and to enhance the efficiency of future wireless communications systems. The key objective of WHERE2 is to assess the fundamental synergies between the two worlds of heterogeneous cooperative positioning and communications in the real world under realistic constraints. The estimation of the position of mobile terminals (MTs) is the main goal in WHERE2. The positioning algorithms combine measurements from heterogeneous infrastructure and complement them by cooperative measurements between MTs, additional information from inertial sensors, and context information. Based on the performance of the geo-aided positioning strategies (in the sense of accuracy, complexity, overhead of signalling, reliability of the provided information, etc.) the impact on coordinated, cooperative, and cognitive networks is assessed. This is done under realistic scenarios and system parameters following on-going standardization processes. A joint and integrated demonstration using multiple hardware platforms provides a verification of the performance of dedicated cooperative algorithms. All the tasks in WHERE2 are covered by different work packages, which are in close interaction to ensure an integral research of cooperative positioning and communications.
