Abstract

Robust RF fingerprinting-based location determination techniques and their system architecture are presented. The techniques are particularly designed for the 4G environment and tested in live mobile WiMAX networks. The causes for the signal measurement variation are identified, and the system is designed taking those into account. Automatic radiomap generation techniques, using the gridding with the interpolation, are proposed to deal with measurements with the missing data and the measurement variation.
