Abstract: Technology for performing dynamic adaptive streaming over hypertext transfer protocol (DASH) is described. A planned route may be selected for a mobile device. Wireless channel information may be received for the planned route from a channel information database (CID). Geographical locations along the planned route where wireless network channel conditions are below a defined threshold may be determined based on the wireless channel information. Additional segments of a media file may be requested from a media server prior to entering the determined locations along the planned route.
