| A method of indoor positioning using Fine Timing Measurement (FTM) protocol with multi-antenna access point (AP) is proposed. In a wireless local area network, an AP has multiple antennas that are strategically located in different physical locations. The AP is used to exchange FTM frames with a wireless station for timing measurement of the FTM frames via its multiple antennas independently. The timing measurement result (e.g., timestamps of transmitting and receiving FTM frames) is then used to determine an absolute location of the station. A simplified Indoor Location operation with simplified deployment is achieved. | ||||||

Die vorliegende Erfindung betrifft unter anderem ein Verfahren zur Erzeugung von Ortungsdaten für die Ortung eines mobilen Kommunikationsendgeräts (20) in einem zellularen Kommunikationsnetz, wobei das Kommunikationsnetz aus einer Anzahl von Funkzellen (40, 50, 60) besteht. Grundlage ist, dass das Kommunikationsendgerät (20) nacheinander eine Verbindung mit einer Anzahl von zwei oder mehr Funkzellen (40, 50, 60) mit gleicher und/oder unterschiedlicher Feldstärke herstellt, dass das Kommunikationsendgerät (20) für eine definierte Zeitdauer die Verbindung mit der jeweiligen Funkzelle (40, 50, 60) beibehält, und dass nach Ablauf der definierten Zeitdauer das Kommunikationsendgerät (20) die Verbindung zu der Funkzelle (40, 50, 50) wieder abbricht und eine Verbindung zu der nächsten Funkzelle (40, 50, 60) herstellt. Aus den dabei entstehenden Informationen werden netzwerkseitig Ortungsdaten erzeugt, mittels derer das Kommunikationsendgerät (20) geortet werden kann. Die Ortungsprozedur ist einfach und kostengünstig, da insbesondere keine kostenpflichtigen Datenverbindungen entstehen.

| A radio user equipment (UE) mobility status is determined in a communications node. UE mobility status measurements associated with the UE communicating over a radio channel are performed. The UE mobility status corresponds to a degree of variation of the radio channel over time. Channel characteristics of the radio channel at a first time and at a second later time are determined. Based on the determined channel characteristics, a channel characteristic error metric is determined and compared to a predetermined threshold. The UE mobility status is determined based on one or more iterations of the threshold comparison. | ||||||

| A method and apparatus for ranging finding of signal transmitting devices is provided. The method of signal reception is digitally based only and does not require receivers that are analog measurement devices. Ranging can be achieved using a single pulse emitting device operating in range spaced relation with a minimum of a single signal transmitter and a single digital receiver and processing circuitry. In general a plurality of transmitting pulsed emitters may be ranged and positioned virtually simultaneously in 3-dimensions (XYZ coordinates) using a configuration of a plurality of digital receivers arranged in any fixed 3-dimensional configuration. Applications may involve at least one single transmitter to receiver design to determine range, or at least one transmitted reflecting signal off from an object to determine range. | ||||||

| Wireless communication terminals and methods are disclosed that determine acoustic ranging synchronized to RF communication signals. A communication terminal can include a RF transceiver, a microphone, and a controller. The controller synchronizes a clock in response to known timing characteristics of received RF communication signals. The controller determines an acoustic signal generation time relative to the RF communication signal synchronized clock at which the other communication terminal will generate an acoustic signal. The controller determines an acoustic signal receipt time relative to the RF signal synchronized clock when the acoustic signal from the other communication terminal is detected in the microphone signal. The controller further determines a propagation time of the acoustic signal from the other communication terminal to the microphone based on a difference between the acoustic signal generation time and the acoustic signal receipt time, and determines a range to the other communication terminal in response to the propagation time of the acoustic signal. | ||||||

| The invention relates to a method and a system for determining and transmitting correctional data of a global navigation satellite system (GNSS). The GNSS comprises a plurality of reference stations that can be used to determine the correction data by repeatedly measuring the position of the reference stations and comparing it to the previously determined exact position. The data determined in this manner are transmitted to a central station via a network and optionally processed in said central station. Such a system requires that every reference station be equipped with a GNSS receiver, but it is especially the connection to the central station that requires considerable financial resources for the establishment of the connection and both for the maintenance and operation of the network. An already existing network consisting of the phasor measurement units (PMU) of a power transmission network is therefore used according to the invention. | ||||||

| The present invention is a new multifunctional low-cost solution for performing measurements and positioning in construction sites and automatically extracting a three-dimensional virtual model, plans, elevations and sections drawings based on these measurements. The preferred embodiment of the present invention consists of a field beacon FB3 or a set of field beacons FB1-FB14, spread around the measured area, communicating by omnidirectional signals with at least one central signal collector 100, which communicates with a computer. Dedicated computer software performs the spatial calculations and other applicable functions. The disclosed system is used for laying out axes and columns at the beginning stage of construction while ensuring the exact match of each mark to its planned position, and for quality and exactitude control of constructions or assembling. In addition the system may be used for locating and tracking objects in a predefined area and automatic directing of machinery to target points. | ||||||

| The invention relates to a method and device for generating a high frequency signal which is particularly suitable for the transmission of time and frequency information. The invention is characterized by a characteristic high-frequency spectrum represented above the axis in the Fig. A lower (3) and higher (4) sideband is symmetrical with the suppressed carrier (2), whereby the spectral bandwidth of said sidebands is low in comparison with the frequency distance (5). Both sidebands are modulated with a spread code in order to resolve ambiguity. The invention also relates to a receiver device which is particularly tolerant with respect to disturbing influences and used to evaluate the group delay time of the high frequency signal. | ||||||

| A method for wireless communication system planning includes, in a first embodiment, determining an image tree (500), based on a transmitter location (401) and the reflective (415) and diffractive (425) surfaces within a coverage region, and limiting the image tree to exclude branching for higher order images requiring more than a predetermined number of reflections and/or diffractions, or potential child images corresponding to surfaces not within the scope of the parent image (530, 560). Based on the image tree and propagation path back-tracing (620), a received signal quality measure (e.g., power) is determined for each receive location. By comparing the different received signal powers, an optimal receiver unit location is determined. Further, by building further image trees for further transmitter locations, an overall coverage quality can be determined for each transmitter and compared to yield an optimal transmitter location. | ||||||

| Methods, systems, and devices are described for determining and updating coordinates of access points (APs) within a location tracking system. Tools and techniques are described that may provide for automatically determining a coordinate set, which represents coordinates of at least three neighboring APs within a location tracking area. These techniques may be utilized at the time of the APs' deployment and/or when APs are moved or relocated to a new location. The methods, systems, and devices may be applicable to single- and multi-floor location tracking systems. Coordinate and/or coordinate sets of APs may be stored in a location tracking server, and they may used in determining a location of tracking tags with the location tracking area. The stored coordinates and/or coordinate sets may be updated as the location of APs change. | ||||||
