Optimizing communication for mobile and embedded devices
View Patent ↗This disclosure relates generally to systems, apparatuses, methods, and computer readable media for optimizing communications for mobile and embedded devices. More particularly, but not by way of limitation, this disclosure relates to systems, apparatuses, methods, and computer readable media to permit mobile devices, e.g., smartphones, tablets, ultrabooks, and the like, which may frequently suffer from intermittent Internet connectivity, e.g., as their owners move around between access points, to estimate the duration of the remaining “window of opportunity” for data transmissions and then select and/or tailor data transmissions to be able to complete as much of the desired data transfer as possible before the expected connectivity loss. In some embodiments, signal strength over time may be analyzed and correlated with a history of connectivity for a particular user and/or device in order to improve the estimation of the remaining “window of opportunity” for data transmission.
