Abstract:
1. A method of receiving data packets via a communication network, comprising: powering down a receiver circuitry prior to a window start time; determining an arrival time for a first data packet received, from a plurality of data packets received, via the communication network; determining the time difference, if any, between the first data packet arrival time and a second received data packet arrival time; determining a variable window size for a window of time during which the receiver circuitry is to be powered-on based on the time difference between the first and second data packet arrival times, wherein the window of time begins at the window start time, wherein the variable window size varies in order to accommodate arrival time jitter; and powering on the receiver circuitry for the duration of the window of time according to the window start time.
