Abstract :
GPS performs considerably well in the outdoor LoS conditions. However, its performance rapidly deteriorates when it is used in non-LoS indoor environments. This paper analyzes the performance of Wi-Fi based positioning in the outdoor environments. Our tests reveal that scene analysis can achieve high accuracies even in the outdoor setups. All observations reported in this work are based on experimental results.
