摘要： An ultrasound and radio frequency technology is used to implement presence sensor capability for wireless devices such as, a laptap device. For example, the laptap device connects to a station device through a WiFi signal. In this example, the WiFi signal may include a data packet that synchronizes internal clocks of the laptap device with the station device. Further, the data packet may include transmitting time information for an ultrasound audio signal generated by the station device. The ultrasound audio signal is received by the laptap device that calculates time of flight (TOF) of the ultrasound audio signal. The TOF may be used to determine actual distance of the wireless device (e.g., laptap device) to the station device.

摘要： Retransmission techniques are disclosed. These techniques may be used in networks employing contention-based access schemes, such as CSMA. For instance, a device may receive a corrupted packet from a transmitting device, and determine a cause of the corruption. When the determined cause of the corruption is an in-network packet collision, the device allows the transmitting device to send a retransmission of the packet in accordance with a contention-based access scheme. However, when the determined cause of the corruption is other than an in-network packet collision, the device provides retransmission assistance to the transmitting device. This retransmission assistance may include a channel reservation for a retransmission, and/or one or more link adaptation suggestions for the transmitting device.
