Abstract: A WLAN device includes a processor implementing a MAC layer and a PHY layer which is coupled to a transceiver including a receive (Rx) chain and a transmit (Tx) chain that is coupled to an antenna. A preamble decode-based receive suspend algorithm has software stored in a memory that is implemented by the processor or by hardware including digital logic. The algorithm responsive to receiving a packet including a Physical Layer Convergence Protocol (PLCP) header, a MAC header, and data, is for analyzing a length field in the PLCP header to determine whether the packet is an undesignated packet and whether there is sufficient time remaining for implementing a turning off and then back on of an analog portion of the Rx chain to avoid missing a next packet. If the undesignated packet and sufficient time are present, the analog portion of the Rx chain is turned off.
