Abstract
A cache server disposed in a motor vehicle receives and caches content from a content distribution network when a load of a cellular link to the content distribution network is low. The cache server determines that the motor vehicle is turned off, broadcasts a wireless signal as part of a wireless network when the motor vehicle is turned off, and provides a device access to the content cached in the cache server via the wireless network.
