Abstract
A method for wirelessly transferring data between nodes may include periodically waking a receiving node from a sleep mode to a receive mode and returning the receiving node to the sleep mode, where, in the receive mode, the receiving node samples a plurality of wake-up channels; transmitting at least one wake-up preamble packet by a transmitting node on at least one of the plurality of wake-up channels; receiving, by the receiving node while in the receive mode, the wake-up preamble packet; transmitting, by the receiving node and responsive to receiving the wake-up preamble packet, an acknowledgement; transmitting, by the transmitting node and responsive to receiving the acknowledgement, a data frame on at least one data channel; and/or receiving, by the receiving node, the data frame. Some methods may include estimating a wake-up time of the receiving node and/or performing a clear channel assessment prior to transmitting the wake-up preamble packet.
