20140077998 | SUPPLEMENTAL LOCATION-RELATED INFORMATION TRANSMIT IN UNASSOCIATED WIRELESS STATES - Systems and methods are directed to information exchange between a location point (LP) and a wireless device. A LP may include a network access point (AP) and/or a dedicated location entity. In one embodiment, supplemental location-related information of a LP including, but not limited to, a geographic location source, geographic location accuracy, geographic location update time, LP type, distance from another LP, and/or timing offset calibration accuracy, may be wirelessly transmitted from a LP to a wireless device. | 03-20-2014 |
20140078910 | REDUCTION OF POWER CONSUMPTION AND TIME FOR TIME-OF-FLIGHT POSITIONING VIA NEIGHBOR LIST - Systems and methods are directed to use of a neighbor list for wireless indoor navigation. The neighbor list may include related information regarding all neighboring access points (APs). The neighbor list can be transmitted, at least partially, to include the related information of a desired number of or all APs in the neighbor list from one AP to a wireless device. The neighbor list can be transmitted in a Neighbor Report Response (NRR) or a time-of-flight (ToF) Response and allow the wireless device to scan for minimal number of APs for ToF measurements. By using the neighbor list, power consumption and time can be significantly reduced during wireless indoor navigation. | 03-20-2014 |
20140094200 | ROTATION-TOLERANT DEVICES AND SCHEMES FOR PEDESTRIAN-DEAD-RECKONING (PDR) LOCATION DETERMINATION - Devices, systems, and methods are directed to the determination of current location information of a wireless communication device. Such devices, systems, and methods include a plurality of sensor elements configured to provide orientation parameter information, velocity and/or acceleration parameter information, and directional heading parameter information; a camera mechanism configured to capture images at predetermined intervals of a user's body as the user handles the wireless communication device; orientation logic configured to determine orientation change information attributable to the user's handling, based on the captured images, and provide orientation correction information; and location estimation logic configured to provide current location information based on previous location information, the velocity and/or acceleration parameter information, the directional heading parameter information and/or the orientation parameter information, and the orientation correction information. | 04-03-2014 |
20140136093 | SYSTEMS AND METHODS OF REDUCING TIMING MEASUREMENT ERROR DUE TO CLOCK OFFSET - Navigation systems for use in indoor environments may include a navigation system that can calculate the time of flight of signals between a navigation device and a WiFi Access Point. Such a calculation can be more accurate not just by using more accurate oscillators in devices, but by correcting the relative error between two devices. This error may be found by determining a timing offset correction, the difference in accuracy between the navigation device and the WiFi Access Point. This may be performed by performing a fine frequency estimation on a long training field or by receiving the PPM offset from another device. Once the PPM offset is determined, the accuracy of the navigation device can be improved by a factor of 50 using a series of equations described in the disclosure. | 05-15-2014 |
20140154996 | APPARATUS, SYSTEM AND METHOD OF CALIBRATING A RADIO DELAY OF A WIRELESS DEVICE - Some demonstrative embodiments include devices, systems and/or methods of calibrating a radio delay. For example, a radio delay calibrator may calibrate at least one radio delay of a radio of a wireless communication device based on one or more calibration messages received by the wireless communication device from one or more other wireless communication devices, the calibration messages including calibration information, which is based on radio delays of the one or more other wireless communication devices. | 06-05-2014 |
20140253385 | COMMUNICATION STATION AND METHOD FOR TIME-OF-FLIGHT POSITIONING USING COOPERATING STATIONS - Embodiments of a communication station and method for time-of-flight (ToF) positioning in a wireless network are generally described herein. In some embodiments, a ToF cooperation table may be received by a positioning station from an access point. The ToF cooperation table may identify one or more cooperating stations and may include information about each cooperating station for ToF positioning. A ToF positioning protocol may be performed with at least some of the cooperating stations identified in the ToF cooperation table using the information in the ToF cooperation table. During the ToF positioning protocol, a current position and a station positional accuracy may be received from each cooperating station. The current position may be a position when ToF is measured. A location of the positioning station may be determined based on the current positions and the ranges to each of the cooperating stations determined from the ToF positioning protocol. | 09-11-2014 |
20140349675 | APPARATUS, SYSTEM AND METHOD OF ESTIMATING A LOCATION OF A MOBILE DEVICE - Some demonstrative embodiments include devices, systems and/or methods of estimating a location of a mobile device. For example, an apparatus may include a wireless communication unit to communicate Time of Flight (ToF) accuracy information corresponding to a location area. The ToF accuracy information may include at least one accuracy indicator corresponding to at least one wireless communication device. The accuracy indicator may indicate an accuracy of a ToF measurement at the location area with the wireless communication device. | 11-27-2014 |
20150045055 | TIME OF FLIGHT RESPONDERS - Apparatus and techniques are described, such as for providing indoor location services. Embodiments include active, passive or independent time-of-flight (ToF) responders that are adapted to provide a device with fine time measurement information to a device in order to determine a distance between the device and the network equipment or a responder. Embodiments may include network equipment coupled to one or more active ToF responders such that the active ToF responders provides ToF information to a device when the network equipment does not support a ToF protocol. Embodiments may include a server coupled to the network equipment, the server being arranged to receive location information from a plurality of devices over a network connection provided by an access point other than the network equipment, and to determine the location of the network equipment and one or more ToF responders coupled to the network equipment based on the location information. | 02-12-2015 |
