    Abstract: A receiver includes power estimation circuitry configured to estimate a first power associated with a first field of a packet and a second power associated with a second field of the packet. The receiver additionally includes channel estimation circuitry configured to determine a second channel estimation of a channel associated with communication of the packet. The second channel estimation is determined based on the first power, the second power, and a first channel estimation of the channel.

    Abstract: Functionality can be implemented for automatic gain control (AGC) in a wireless network device to determine whether to change the gain of the wireless network device based on determining the strength of an RF signal. At various time instants, the strength of the RF signal can be compared against different thresholds to determine the presence of and severity of the saturation of the RF front end. The gain settings can be adjusted based on comparing the strength of the RF signal with a set of thresholds. This can help the wireless network device receive RF signals with little or no distortion, and can minimize RF saturation, gain compression, false detection and other performance degradation at the wireless network device.

    Abstract: Methods, systems, devices, and apparatuses are described for wireless communications in which first type of traffic may be transmitted from a gateway access point (AP) directly to a station. Beacon signals transmitted to the station are transmitted as part of the first type of traffic. A second type of traffic may be transmitted from the gateway AP to the station via at least one relay AP. The first type of traffic may include low-throughput traffic and may be transmitted over a long-range radio link (e.g., 2 GHz band link or sub-1 GHz band link). The second type of traffic may include high-throughput traffic and may be transmitted over at least one short-range radio link (e.g., 5 GHz band link). The gateway AP may receive low-throughput traffic directly from the station and high-throughput traffic from the station via the at least one relay AP.

    Abstract: Systems and methods are provided for preferentially locating a candidate channel likely to have an active network during a WLAN scanning process. A portion of a first incoming packet on a first wireless channel is received and analyzed to determine whether an active network is available on the first wireless channel. The reception of the first incoming packet is selectively aborted based at least in part on the analysis. The portion of the first incoming packet may be a header of the first incoming packet. The reception of the first incoming packet may be aborted in response to a trigger condition. The trigger condition may correspond to a determination that the first incoming packet is not a packet of interest, a determination that the first incoming packet is not a beacon, or a determination that a signal strength on the first incoming packet is below a threshold level.
