Abstract: An example system includes a transceiver. The transceiver communicates multicast frames to a plurality of client devices in a multicast group. The system further includes a controller. The controller determines that a predetermined time has passed since the transceiver most recently sent a unicast transmission to one of the plurality of client devices. The controller instructs the transceiver to transmit a unicast frame to the one of the plurality of client devices. The controller computes a data rate for the one of the plurality of client devices based on the transmission of the unicast frame to the one of the plurality of client devices.

Abstract: Described herein are techniques for determining a location of a disconnected device. In an example, a method includes instructing a first access point to sniff a wireless channel for probe request packets from disconnected devices, and instructing the first access point to send a distance-probing packet to a disconnected device after receiving a probe request packet from the disconnected device. The method further includes receiving, from the first access point, a MAC address of the disconnected device determined from the received probe request packet. After receiving the MAC address from the first access point, a group of access points is instructed to send distance-probing packets to the disconnected device. The method further includes receiving, from the first access point and the group of access points, time-of-flight measurements associated with the disconnected device. A location of the disconnected device can be determined using the time-of-flight measurements.

Abstract: Localizing a location of a mobile device may be performed by obtaining times of flights between the mobile device and an access point at a first and second location. A heading of the mobile device and a distance between the first and second location may be further obtained. The times of flight, heading, and distance may be used to localize the second location.

Abstract: A set of antennas is selected from a plurality of antennas for transmitting data streams on a plurality of subcarriers based on channel state information of a communications channel between the plurality of antennas and a plurality of receive antennas at a client device, a number of the data streams to be transmitted, and a channel coherence time of the communications channel. A size of the set is equal to or greater than the number of data streams.

Abstract: According to an example, a signal space based navigation apparatus may receive traces of wireless signal observations and corresponding pedestrian deadreckoning (PDR) traces between different ones of the wireless signal observations from a plurality of user devices. A plurality of wireless clusters may be generated based on the traces of wireless signal observations. A PDR displacement vector may be generated between two or more of the wireless clusters based on the two or more of the wireless clusters and a subset of the PDR traces corresponding to the two or more of the wireless clusters. A sensing map may be generated based on the plurality of wireless clusters and a plurality of PDR displacement vectors including the PDR displacement vector.

Abstract: A technique includes determining a consumption time for content received in a mobile device from a cellular network, where the consumption time represents a time at which the content is received in the mobile device to a time at which content associated with the received content is consumed at an output sink of the mobile device. The technique includes regulating a power consumption state of a cellular radio of the mobile device based at least in part on the consumption time.

Abstract: According to an example, mobility-aware frame aggregation may include using mobility information related to a transmitter and/or a receiver associated with transmission of data over a wireless channel to determine an aggregation size for frame aggregation of the data to be transmitted over the wireless channel. The mobility information may be based on subcarriers and antennas related to the wireless channel.
