A method and system for link quality metric based antenna selection for transceiver are disclosed. In one embodiment, a method for selecting an antenna from multiple antennas associated with a receiver, includes receiving multi-carrier modulated signals via a currently active antenna of the receiver, and estimating a predicted packet error rate (PER) associated with a current receive path of the receiver. The current receive path is used to process the multi-carrier modulated signals. The method further includes selecting a next antenna from the multiple antennas for forming a next receive path of the receiver based on the predicted PER and a packet error history associated with at least one previous receive path.

A method of managing a mobile station (e.g., IEEE 802.11 station) having a serving BSS, uses a station connection manger and initially maintains a default idle stable state with minimum power to receive incoming calls. While idle, the station periodically polls and scans a detected BSS (Access Point) to detect messages using DTIM (Delivery Traffic Indication Message). A null frame sent, triggers corresponding frame transmission at an Access Point. If the null frame is acknowledged, the station switches to the active state until end of packet exchange. With no null frame acknowledged, scanning is resumed to update a BSS list prior to joining a newly found BSS via authentication and association states. When no candidate BSS is found, a time out period is used before next polling. After the last message frame is transmitted, the station resumes the default idle state. The station manager conserves battery power in the station.
