Abstract
A system and method for maximizing the standby time of mobile communication devices that have WiFi or other high energy-consuming network interfaces, by predicting in real time actionable silent periods (ASPs) of the interface and shutting the interface down during these ASPs. Standby times are significantly increased, resulting in longer periods of operation before battery charging is required, while keeping minimal the probabilities of missing incoming data packets when the interface is turned off.
