Abstract: This disclosure provides systems, methods and apparatuses for performing ranging operations between a transmitting device and one or more receiving devices using one or more wireless channels. In some implementations, a transmitting device may substantially concurrently exchange, on each of a plurality of wireless channels, a corresponding set of FTM frames and acknowledgement (ACK) frames with a receiving device, and then determine a distance to the receiving device based on the plurality of exchanged sets of FTM and ACK frames. In some other implementations, the transmitting device may substantially concurrently exchange, with each of a plurality of receiving devices, a corresponding set of FTM frames and ACK frames on a corresponding one of a plurality of wireless channels, and then determine a distance to each of the plurality of receiving devices based on the corresponding sets of exchanged FTM and ACK frames.

Abstract: Disclosed embodiments facilitate wireless channel calibration, ranging, and direction finding, between networked devices. A method on a first station (STA) may comprise: broadcasting, at a first time, a first NDPA frame to a plurality of second STAs. The first NDPA frame may include a first bit indicating that one or more subsequent frames comprise ranging or angular information. After a Short Interval Frame Space (SIFS) time interval from the first time, a second frame may be broadcast. The second frame may be a Null Data Packet (NDP) frame. In response, a plurality of Compressed Beamforming (CBF) frames may be received at the first STA where each CBF frame may be received from a distinct corresponding second STA, and may include Channel Feedback Information field with information pertaining to communication channel between the first STA and the corresponding second STA. The communications may be encoded using Orthogonal Frequency Division Multiple Access.

Abstract: Apparatuses and methods are disclosed that may perform ranging operations between a first device and a second device. The second device transmits an FTM request frame indicating a number of supported non-legacy ACK frame formats, and receives a first FTM frame indicating capabilities of the first device to receive each of the non-legacy ACK frame formats supported by the second device. The second device selects one of the non-legacy ACK frame formats or a legacy ACK frame format based, at least in part, on the indicated capabilities of the first device, and then transmits ACK frames using the selected frame format during the ranging operation.

Abstract: Disclosed are processes, devices and systems for exchanging messages between devices in support of measuring ranges between devices. In one particular implementation, a first wireless transceiver device may transmit one or more fine timing measurement (FTM) messages to a second wireless transceiver device, and receive a message acknowledging receipt of at least one of the one or more FTM messages. The first wireless transceiver device may authenticate the received message as being transmitted from the second wireless transceiver device.

Abstract: Techniques for providing neighbor reports for use in passive positioning of a client station are disclosed. An example method for broadcasting network neighbor reports according to the disclosure includes generating a beacon transmission, determining a neighbor report count value, if the neighbor report count value is greater than zero, then broadcasting the beacon transmission including at least a beacon frame and the neighbor report count value, and decrementing the neighbor report count value; if the neighbor report count value is equal to zero, then broadcasting the beacon transmission including at least a beacon frame and a neighbor report, and resetting the neighbor count value.

Abstract: Disclosed are methods, systems and devices for obtaining a range between devices based, at least in part, on an exchange of wireless messages. For example, wireless devices may obtain measurements of range based, at least in part, on an exchange fine timing measurement (FTM) messages. In one implementation, an initiating wireless station may transmit an initial FTM request message comprising one or more fields to a responding wireless station specifying an indefinite duration for a requested session to transmit FTM messages to the initiating wireless station.
