Abstract: Disclosed is a system, apparatus, computer readable storage medium, and method to perform a bandwidth efficient network based positioning (NBP). A positioning request for a mobile device is received within an environment, the environment comprising one or more access points (APs). An AP coverage area including the mobile device is determined A NBP load for the AP is measured, wherein the NBP load comprises a direct NBP load and an indirect NBP load. If the NBP load is less than a threshold, the AP is instructed to process the first positioning request. Multiple APs may process positioning requests concurrently and positioning requests may be scheduled according to timeout and/or relative expiration.

Abstract: Disclosed are implementations that include a method, performed by a network control device, including sending a first instruction to a first device to send a first measurement signal, and sending a second instruction to a second device to receive the first measurement signal. Following receipt of a first acknowledgement signal from the target mobile device, the first and second devices change their roles so the second device sends, and the first device receives, a second measurement signal, and the first and second devices receive a second acknowledgement signal from the target device. Position of the target device is determined based on timing measurements associated with the first and second measurement signals, the first and second acknowledgement signals, and on known positions of the first and second devices. Another network device is selected to perform additional measurements upon a determination that a desired accuracy of the position determined was not achieved.

Abstract: Systems, methods, and devices enable group associations based on network determined location information. The various embodiments enable the ad-hoc creation of mobile device groups based on network determined locations. In an embodiment, a server may determine the location of a mobile device and based on the mobile device being located in a pairing zone may add the mobile device to a group. In an embodiment, the server may add the mobile device to the group following the occurrence of a trigger event, such as the mobile device pausing in a given pairing zone for a period of time. In an embodiment, the server may identify that mobile devices are located within a pairing zone and may add all the mobile devices in the pairing zone to the same group.

Abstract: A wireless network is disclosed that allows an access point (AP) to keep a station (STA) in an awake state for an extended duration by periodically sending “keep-awake” frames to the STA. The keep-awake frames may be NULL frames having an asserted “more data” bit. For some embodiments, the AP transmits a beacon frame to the STA, wherein the beacon frame includes an asserted traffic indication bit that causes the STA to remain in the awake state for an additional wake-up period. Then, the AP transmits a sequence of keep-awake frames to the STA, wherein each keep-awake frame causes the STA to remain in the awake state for an additional time period.

Abstract: A ranging operation between an initiator device and a responder device may be performed by receiving, from the initiator device, a data frame including a request for the responder device to report its actual Short Interframe Space (SIFS) duration to the initiator device; creating a response frame; determining the actual SIFS duration based on the received data frame and the response frame; embedding SIFS information indicative of the actual SIFS duration of the responder device into the response frame; and sending the response frame to the initiator device.
