Abstract:
Apparatuses, methods, and computer-readable media for a context-based access mediator (“CAM”) are described. The CAM may be configured to mediate access to computer-accessible resources by a user using a computing device after receiving a request from the computing device for the computing device to access a computer-accessible resource. The computer-accessible resource may be local or remote to the computing device. The CAM may be configured to receive the request and to mediate access to the requested resource. Such mediation may be performed through the CAM determining whether the resource may be accessed by the computing device and/or through the CAM determining which resources are available to the be accessed by the computing device. The CAM may be configured to mediate access to computer-accessible resources based on information about a context for the computing device and/or computer-accessible resource. Other embodiments are described and claimed.
Abstract:
Technologies for identifying rogue access points having an actual location different from a registered location include a computing device to receive a unique identifier of each access point of a plurality of access points within a communication range of the computing device from the corresponding access point. The computing device determines a registered physical location of each access point based on the unique identifier. Additionally, the computing device determines a reference distance between the computing device and each access point based on a transmitted signal received from each corresponding access point and a spatial distance between each access point and each other access point based on the registered locations of the access points. Based on the spatial distances and reference distances, the computing device identifies which of the access points are rogue access points.
Abstract:
Embodiments of techniques and systems for distance and location estimation in wireless systems are described. In embodiments, a wireless device may receive wireless signals from reference points in a spatial arrangement. The wireless device may identify a closest reference point and generate arrangement-based distance values for each of the reference points based on a propagation model. The wireless device may adjust the propagation model based on the received wireless signals and the arrangement-based distance values, and may generate adjusted distance values using the adjusted propagation model. The wireless device may use the adjusted distance values and the spatial arrangement to estimate the location of the wireless device. Other embodiments may be described and claimed.
Abstract:
In embodiments, apparatuses, methods, and storage media may be described for identifying a quick response (QR) image. A QR control code (QRCC) may be identified in the QR image based on a QR tag in the image. Based on the QRCC, a control command of an apparatus may be identified. Other embodiments may be described and/or claimed.
Abstract:
A method and system for detecting and reducing data transfer congestion in a wireless access point includes determining a round-trip-time value for an internet control message protocol (ICMP) packet transmitted from a source computing device to a first computing device of a plurality of computing devices via the wireless access point. A data rate for data transmissions from the source computing device is increased to a value no greater than a peak data rate value if the round-trip-time is less than a first threshold value. The data rate is decreased if the round-trip-time value is greater than a second threshold value. Additionally, the peak data rate value may also be decreased if the round-trip-time value is greater than the second threshold value.
Abstract:
Embodiments for providing intelligent location-based signage services are generally described herein. An intelligent signage device may include a proximity module arranged to receive a notification that a personal device is within an area of the intelligent signage device. The signage may also include a transceiver arranged to establish a connection from the intelligent signage device to the personal device and receive user data from the personal device via the connection. An offer-customization module of the digital signal may be arranged to determine a set of display options based on the user data, a member of the set of display options corresponding to an offer for a product and a presentation module of the digital signage may be arranged to display the member of the set of display options on the intelligent signage device.
Abstract:
Embodiments of methods, systems, and storage medium associated with providing, with a user device, multiple content items for display by multiple receiving devices via multicast transmissions are disclosed herein. In one instance, the method may include forming a multicast data unit with multiple portions of data. Each portion of data may correspond to one of multiple content items to be transmitted to multiple receiving devices by the computing device and each content item is to be displayed by one of the multiple receiving devices. The method may further include transmitting the formed multicast data unit to the multiple receiving devices; and initiating, at each receiving device of the multiple receiving devices, a retrieval from the multicast data unit a portion of data that corresponds to a content item to be displayed by the receiving device, and to display the content item. Other embodiments may be described and/or claimed.

Abstract:
A method of generating wireless signal information includes receiving relative movement data generated by sensors and wireless signal data generated by a wireless signal module at a computing system, the sensors and module for detecting wireless signals located in a portable electronic device (PED). The method further includes generating landmark information at a landmark detection module based on the relative movement data, the sensor data and the wireless signal data. The method further includes generating a plurality of Simultaneous Localization and Mapping (SLAM) estimate locations based on the landmark information and the relative movement data at a SLAM optimization engine. The method further includes assembling a first database of locations and corresponding wireless signal strength and access points. The method further includes generating additional information concerning locations and wireless signal information based on the first database.
Abstract:
Methods and mechanisms for exchanging map information in a wireless communication. In an embodiment, map information to represent at least a portion of a map is advertised by a first communication device communication independent of any request for the map information being received in a data session or a voice session. In another embodiment, a second communication device receives the wireless communication and generates a representation of the map based on the advertised map information.
