How About the Real Capacity of Cell-ID Based Algorithms for LBS

We investigate the location algorithms of which parameters could be extracted from measurement reports. A field measurement was implemented for collecting data, and algorithms were programmed for examining their accuracies. The experiment results represent diversity from the previous work and our theoretical analysis. The position accuracies are ungratified and some algorithms which have been considered as high accuracies, in contrast, largen the errors. We also suggest an improvement. As a simple threshold to obstruct the rough data, position accuracy and stability could be enhanced significantly.
