Research Project 'ROSI-3D'

RFID locating in consideration of mobile objects in a radio field with 3D-simulation support.

Accurate locating of objects in indoor spaces is a research and development challenge that can – in comparison to other wireless technologies – be solved particularly inexpensively with RFID (Radio Frequency Identification). Caused by increasing implementation of RFID systems there is a need of locating solutions in almost all sectors in the industry.

The project aims to improve locating of objects in dynamic environments significantly from a technical and economic perspective, by joining new approaches from RF engineering and computer science, as well as additional economic considerations.

Previous approaches of locating are generally focused on RFID systems with active transponders where each transponder requires its own power supply. In static environments and without the general awareness of mobile objects in the radio field accuracies of less than 1 m are possible. However, these approaches ignore significant boundary conditions of industrial as well as public interiors: Many objects (people, vehicles, tools, materials) are usually in motion and thus constantly affect the transmission field. Because of these circumstances, there is currently no satisfactory solution of radio location that can be operated economically.

The research project ROSI 3D takes two main approaches for the improvement of radio-based tracking solutions: (1) Through acquiring real world conditions, a 3D model should be created, which leads to a generalized form that can be used for different applications. In it, areas of differing radio propagation and the presence of non-stationary objects inside the RF field must be considered. This approach follows current models of forecast of dispersion in mobile radio. (2) By using a time-dynamic 3D simulation, interfering objects can be considered in the process of locating. Furthermore, the technical setup of an infrastructure is optimized and supported by augmented reality.

This approach – based on multi-antenna systems with multiple objects in space – will also be more economically sound than previous approaches, because transponders and radio terminals do not require own power supplies. The number and optimal location of necessary reading devices will be determined by virtual performance tests with variable objects in simulation. The 3D simulation thereby reaches far beyond capabilities of other radio technologies used by site surveys, which are tuned to static environments.

Evaluation of models and the simulation system will be done in field trials together with the practice partners in different environments and frequency bands. For the practical use of the locating system, scenarios in assembly halls, in mining or event-/exhibition areas are envisioned.
