Abstract: Nowadays the inconsistent structure and incompatibility with different locating devices of wireless locating application have dramatically slow down the wireless locating application development life cycle and maintenance.Application framework abstracts the common elements of wireless locating applications and helps to improve software reuse and shorten the development lifecycle.In this paper，a wireless locating application framework which supports data fusion of various locating devices is proposed，aiming to separate business logic from underlying locating platform and standardize the structure of wireless locating application.Besides，an instance of this framework is given，core techniques are introduced，the framework’s effectiveness and usefulness is validated.
