Abstract: System and method for implementing a time-switched MIMO signal analysis using a single RF signal receiver to capture the multiple incoming data packet signals. In accordance with example embodiments, like portions of repetitive data slots may be captured with a periodicity equal to that of their host repetitive data frames.

Abstract: A method includes collecting roaming connectivity information for a plurality of wide area networks from a plurality of mobile devices, independently of the wide area networks, receiving the roaming connectivity information at a server and relating the connectivity information to the wide area networks and to a plurality of geographic locations to create a roaming network connectivity information database, generating a list of candidate wide area networks to serve as roaming networks for a specific mobile device and a given location based on the roaming connectivity information, and sending a preferred roaming list to the specific mobile device, the preferred roaming list including the list of candidate wide area networks. The method may include receiving location prediction information from the mobile device, and generating the list of candidate wide area networks based on a predicted location.

Abstract: A method includes collecting physical layer and data layer connectivity information from a plurality of wide area networks using a plurality of mobile devices independently of the wide area networks. A server receives the physical layer and data layer connectivity information, relates the connectivity information to specific wide area networks and to a plurality of geographic locations to create a network statistics database. The server also receives mobile device state information including mobile device location information and predicts that connectivity for a specific mobile device will fall below acceptable criteria based on the network statistics database. The server generates a list of candidate donor mobile devices to serve as data connection sources for the specific mobile device based on the network connectivity information and the mobile device state information and selects a donor device from the list of candidate donor devices based on a weighting algorithm.
