摘要:
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.

Some demonstrative embodiments include devices, systems and/or methods of orientation estimation of a mobile device. For example, a mobile device may include an orientation estimator to detect a pattern in at least one image captured by the mobile device, and based on one or more geometric elements of the detected pattern, to determine one or more orientation parameters related to an orientation of the mobile device.

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.

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.

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.
