    Abstract: A receiver includes a phase click detector, a controller, and a comparator. The phase click detector detects phase clicks in an input signal, where a phase click corresponds to a change in phase of at least a first threshold. The controller is coupled to the phase click detector for calculating a number of phase clicks within one or more time periods. The comparator compares the number of phase clicks within the one or more time periods, and provides an arrival signal if the number of phase clicks is less than a second threshold.

    Abstract: In one aspect, a method includes: enabling, via a controller of a network device, a receiver of the network device for a plurality of receive fragments during a receive duration; analyzing a signal fragment received during at least one of the plurality of receive fragments to identify possible presence of a wake-up frame sent by a coordinator device; and in response to the identification of the possible presence of the wake-up frame, enabling the receiver to receive and detect another wake-up frame.

    Abstract: A system for automatically detecting the PHY mode based on the incoming preamble is disclosed. The system includes a multimode demodulator, which includes a preamble detector and a demodulator. The preamble detector is used to determine when the preamble has been received and the PHY mode being used by the sending node. An indication of the PHY mode is supplied to the demodulator, which then decides the incoming bit stream in accordance with the detected PHY mode. In some embodiments, one demodulator, capable of decoding the bit stream in accordance with a plurality of PHY modes is employed. In other embodiments, the system includes a plurality of demodulators, where each is dedicated to one PHY mode.

    Abstract: An apparatus includes a transceiver having a MAC controller and a PHY controller. The MAC controller is configured to selectively omit at least a portion of a field of a media access control (MAC) frame. The PHY controller is configured to insert the MAC frame into a physical protocol data unit and to selectively configure a portion of the physical protocol data unit to indicate omission of at least the portion of the field from the MAC frame.
