Abstract
A method includes, in a receiver that includes an uncompensated crystal oscillator, receiving signals from a transmitter by activating the receiver periodically at intervals corresponding to a specified wake-up time period. In response to detecting at the receiver that the specified wake-up time period is insufficient for maintaining synchronization between the receiver and the transmitter using the uncompensated crystal oscillator, an actual wake-up time period, smaller than the specified wake-up time period, is selected. The receiver is activated periodically according to the selected actual wake-up time period.
