Positioning services become overcrowded. Accuracy is the main quality criteria in positioning. But to better appreciate this one a coefficient is needed. In this paper we present Geometric and Signal Strength Dilution of Precision (DOP) for positioning systems based on Wi-Fi and Signal Strength measurements. %K Wireless LAN %K Radio position measurement %K Indoor radio communication %K IJCSI %U http://www.ijcsi.org/papers/3-35-44.pdf
