N2 - WLAN Access Point network is typically optimized for communication scope, and not for localization. It is thus important to understand the positioning accuracy limits under a certain given Access Point topology and to be able to make design recommendations if the Access Point topology can be adapted better for the navigation needs.

Two study cases are presented about how the proposed criterion can be used to choose the optimal Access Point density and the optimal Access Point topology in a network designed for positioning purposes.
