Abstract: Various embodiments include systems and methods of determining whether a compromised access point is present in a communication network. A processor of a wireless communication device may predict one or more websites that the wireless communication device will access during a future session with the one or more websites. The processor may establish a secure connection with the communication network, request a digital certificate for one or more of the predicted websites, and store a digital certificate received from each of the predicted websites. The processor may determine whether a compromised access point is present in the communication network by comparing one of the digital certificates from the predicted websites with a digital certificate received from a website server during a current session.

Abstract: Systems, apparatus and methods for selecting a base station or a set of base stations for RTT measurements, or other interactive radio localization technique, to determine a position fix of a device are presented. The method imposes a processing load on only inactive or less active base stations. Busy or busier base stations are not used in the interactive radio localization technique. By imposing a processing load on only less active base stations, transmitting devices may be under loaded and encounter a more uniform processing delay, and thus provide a more accurate measurement resulting in a more accurate position fix.

Abstract: Techniques for providing a user with an augmented virtuality (AV) experience are described herein. An example of a method of providing an AV experience includes determining a location of a mobile device, determining a context based on the location, obtaining AV object information, displaying the AV object information in relation to the context, detecting an interaction with the context, modifying the AV object information based on the interaction, and displaying the modified AV object information. The context may include weighting information. The weighting information may be based on Received Signal Strength Indication (RSSI) or Round-Trip Time (RTT) data. The weighting information may be associated with a composition of a physical object in the context. A user gesture may be received, and the AV object information may be modified based on the received gesture information.

Abstract: Methods and devices include a server and at least two web browsers operable on at least two different computing devices. A server processes requested code to return binary code as metadata to assist a computing device render a webpage. The server transmits the generated metadata to at least one computing device. The computing device renders a webpage using at least a portion of the provided metadata. The metadata may identify portions of JavaScript that can be processed in parallel. The metadata may identify a library portion that does not have to be loaded. The metadata may identify a portion of the webpage that may be rendered first before a second portion of the webpage. Returning metadata to the computing device can assist the computing device in parsing, analyzing or executing the request for the webpage.
