Spatial data channel in a mobile navigation system

With growing popularity of mobile devices and wireless communications, mobile location-based services that deliver location dependent and context sensitive information to mobile users are emerging as one of the hot topics of mobile. In this paper, we introduce a mobile navigation solution and discuss spatial data management strategies for mobile navigation service to answer the challenge of providing spatial map data efficiently. And a model, Spatial Data Channel, is devised for integrating various strategies including data preparation, transmission and management. Finally, we present some conclusions.
