    Abstract: Certain aspects of the present disclosure generally relate to using bloom filter hash functions for service hint information in advertisements such as beacons and probe responses. Certain aspects provide an apparatus for wireless communications, such as an access point (AP). The apparatus generally includes a processing system configured to generate a plurality of bitmaps that indicate one or more services known by the apparatus, each bitmap being generated by applying a different set of one or more cyclic redundancy check (CRC) based hash functions to one or more service identifications (IDs) of each service, and to generate one or more frames, each frame including one of the plurality of bitmaps and an indication of the set of one or more CRC based hash functions used to generate the bitmap included in the frame, and an interface configured to output the one or more frames for transmission.

    Abstract: Methods, systems, and devices are described for wireless communication at a wireless communications device. The device may use several antennas to receive a signal, one of which may be shared between two radios. During signal reception, a radio may detect when the shared antenna is abruptly taken over by the other radio. The radio may detect the loss of the antenna by measuring an impedance mismatch. Alternatively, the radio may reference an antenna switch control that is used to facilitate the switch. After detection, the radio may recover from the antenna loss by adjusting signal processing. For example, the radio may modify a maximal ratio combining (MRC) operation. In certain examples, the device may disregard the signal version from the shared antenna in the computation of MRC weights. In some cases, the device may interrupt an MRC weight computation and use MRC weights from a previous calculation.

    Abstract: Systems, methods, and devices are disclosed for managing possible mergers between neighbor-aware or social Wi-Fi network clusters in a wireless network. In one aspect, a method includes identifying, at a device of a group supported by a first wireless network cluster, a neighboring wireless network cluster. The method further includes joining the neighboring wireless network cluster while remaining in the first wireless network cluster. The method further includes determining whether to stay with either the neighboring wireless network cluster or the first wireless network cluster based on information from the neighboring wireless network cluster or the first wireless network cluster. The method further includes announcing a decision to leave the first wireless network cluster or the neighboring wireless network cluster.

    Abstract: A first wireless device may receive a ranging proxy indicator from a candidate ranging proxy and identify a first ranging indicator based at least in part on the ranging proxy indicator. The first ranging indicator may indicate a proximity of the first wireless device to the candidate ranging proxy. The first wireless device may receive a second ranging indicator indicating a proximity of a second wireless device to the candidate ranging proxy. The first wireless device may identify that the first wireless device and the second wireless device are within a proximity threshold based at least in part on the first ranging indicator and the second ranging indicator.

    Abstract: Methods, systems, and devices are described for determination of a route through a geographic area using neighbor awareness network (NAN) devices. A plurality of NAN devices may be distributed throughout a geographic area and may monitor the environmental conditions of their respective locations. The NAN devices may relay the environmental condition information to a route determining device, which may determine a route through the geographic area. The determined route may be based at least in part on the environmental condition information received from the NAN devices. The route determined route may be communicated to a mobile target associated with the geographic area.
