Abstract
A client device dynamically selects one of client based location computation and server based location computation, based on propagation environment around the client device, to determine its own location. The client device may switch between client based location computation and server based location computation based on the local propagation environment for a desired quality of location and low data load from a remote location server. The client device measures power of received radio transmissions from radio transmission sources such as WLAN access points and/or cellular base stations. For a client based location solution, the client device performs location computation utilizing the local power measurement and assistance data downloaded from the remote location server. For a server based location solution, the remote location server may perform location computation for the client device. The client device determines the corresponding server based location solution by decoding information received from the remote location server.
