Embodiments of the present invention pertain to methods and systems for communicating information to a roving positioning device. In one embodiment, a cellular communication device, a non-cellular wireless communication device, and a computer networking device for forwarding data packets are coupled with a bus. A request originating from a roving positioning device for a location-specific position correction is received via the non-cellular wireless communication device. A controller coupled with the bus causes the request to be forwarded via the cellular communication device.
