Abstract
Selectively caching content related to routing data in a computing device. Prior to traversing a route, one or more access points to a network are identified. An expected level of access to a network (e.g., signal strength) along the route is determined. Portions of the route are selected based on the expected level of access. Content corresponding to at least one of the selected portions is received and stored for access during traversal of the route. For example, map images for areas expected to have poor network connectivity are cached prior to traversing the route to ensure that routing data is displayed to a user when in those areas. During transversal of the route, content is obtained and cached if a current level of access is less than a defined threshold.
