摘要： Machine-readable media, methods, apparatus and system for determining a route metric are described. In some embodiments, a characteristic of a packet to be sent from a node to another node is analyzed. The characteristic of the packet may indicate at least one of a group consisting whether the packet is transmission quality sensitive and whether the packet is transmission throughput sensitive. Then, a weight relationship between a packet loss rate and a data rate may be determined, in which the weight relationship may vary with the characteristic of the packet. A route metric for a route from the node to the another node may be determined based upon the packet loss rate, the data rate and the weight relationship.

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.
