Abstract: A method of analyzing location data of mobile communication devices. The method comprises determining a dwell time of each of a plurality of mobile communication devices in location clusters associated with each device by an application that executes on a computer, determining a centroid of the location clusters by the application, for each of the plurality of mobile communication devices, determining by the application centroids of the location clusters associated with the mobile communication device that are located within a predefined geometry, analyzing by the application the dwell times of mobile communication devices in the predefined geometry based on the determination of centroids that are located within the predefined geometry, and building a building traffic flow survey by the application based on the analysis of dwell times of mobile communication devices in the predefined geometry.

Abstract: An ad gateway is disclosed. The ad gateway comprises a processor, a memory, and an application stored in the memory. The application when executed by the processor, determines a type of network connection by which a mobile communication device is communicatively coupled to a communication network and a current quality of service (QOS) level of the communication network. The application then selects an advertisement type based on the type of network connection and based on the current QoS level of the communication network. The application then requests an advertisement of the selected type for the mobile communication device from an advertisement data store, wherein the advertisement types comprise a static image type, an animation type, a video type, and a high definition video type. The application then receives the advertisement from the advertisement data store. The application then transmits the advertisement to the mobile communication device.
