摘要： In a system for geopositioning receivers in areas substantially inaccessible to satellite signals, multiple access points configured to periodically transmit management frames (i) via a single shared communication channel and (ii) using a modulation scheme associated with a rate of at least 50 Mbps. A database stores respective locations for each of the access points. A portable computing device is configured to retrieve the location of the access points from the database and, when moving through a region in which the of access points are disposed, receive at least one management frame from each of the access points within a limited time interval on the single shared communication channel. The portable computing device is further configured to determine a current position of the portable computing device based on the management frames using the retrieved locations of the access points.

摘要： A mobile device receives signals from transmitting devices and generates sets of signal metrics based on the received signals. The mobile device also receives indicated locations, where each indicated location is associated with a respective set of signal metrics. The mobile device provides location-specific data to a transmitting device locating engine to estimate locations of the transmitting devices, where the location-specific data includes data representing the sets of signal metrics and data representing the indicated locations. The mobile device further receives an indication of sharing criteria via a user interface of the mobile device, and causes the estimated locations to be selectively shared with one or more other mobile devices based on the sharing criteria.

摘要： The method for localisation and mapping of pedestrians or robots using Wireless Access Points comprises the following steps: - Wireless Signal Strength and/or time delay measurements from wireless access points (e.g. Wireless Local Area Network access points (WLAN, Wifi, WIMAX), or mobile radio base stations (e.g. GSM, UMTS, LTE, 4G, IS95 or RFID tags or transmitters) are taken at regular or irregular time instances by a device carried by the pedestrian or robot in addition to odometry measurements (e.g. human step measurements, human pedestrian dead-reckoning, robot or wheelchair wheel counter measurements, robot motor or wheelchair motor control inputs), and - providing a particle filter which has a state model that comprises the pedestrian or robot location history for each particle, and also the location probability distribution of one or more wireless access points, - wherein at each time-step of the particle filter each particle of the particle filter is weighted and/or propagated according to the odometry measurements and weighted and/or propagated according to the wireless measurement, - wherein at each time-step of the particle filter the location probability distribution of the wireless access points for each particle is updated according to the measurement and the previous location probability distribution of that particle, and - wherein the location of the pedestrian or robot and/or the map of the wireless access point(s) is extracted from the particle population (e.g. from the state of the particle with greatest weight, from the weighted state across all particles, from the state of a randomly chosen particle, from the state of the maximum likelihood particle).

摘要： Disclosed is a method performed by a position calculation node (160) in a wireless communication network (100). The node (160) is arranged for improving accuracy when determining positions in the wireless communication network. The method comprises obtaining a signal transport time value for each of a plurality of different geographical UE positions (UE1, UE2, UE3), wherein the respective signal transport time value relates to the time it takes for a radio signal to travel between a first base station and one of the plurality of UE positions. The method further comprises obtaining a geographical position value for each of the plurality of different geo-graphical UE positions, the position values being independent of the signal transport time values, and determining an actual geographical position for the first base station, based on the obtained signal transport time values, the obtained position values and a predefined geographical position for the first base station.

摘要： Embodiments of the present invention disclose a method for obtaining time of arrival TOA when a mobile terminal is located, including: receiving a locating reference signal sent by a locating transmitter; performing time domain related processing on the locating reference signal and a synchronization reference signal sequence to obtain a related spectrum value of a multipath signal component corresponding to a delay value; detecting a channel parameter used when the locating reference signal is received, and generating, according to the channel parameter and a function that progressively decreases with the delay value, a related spectrum threshold that progressively decreases with the delay value; and traversing the delay value in ascending order of the delay value, searching for a first traversed delay value whose related spectrum value of a multipath signal component corresponding to the delay value is greater than a related spectrum threshold corresponding to the delay value, and using the found delay value as TOA for outputting.
