Network geo-location system

ActiveUS7200658B2Prevent address spoofing (forging)Multiple digital computer combinationsTransmissionGeotargetingIp address
A method for accurately determining the geographic location of a PC or other networked device on the Internet. Client software furnished by a service provider performs trace-route or other network analysis commands to known servers (e.g., eBay, Yahoo, Amazon) or even servers at random locations. The client collects an array of IP address and other network information as a result of the trace-routes, and the trace-route IP information is then transmitted to the service provider that is trying to identify the geographic location of the client. Using the array of IP addresses thus generated, the Internet server software can analyze location information of each Internet hop within each trace-route. For example, the server might look at the first five hops from the client to the server. If four of the five routers have addresses within the geographic area of interest, the server can conclude that the client is probably within the geographic area.

Vector network analyzer applique for adaptive communications in wireless networks

A test signal generator at a transmitter station and a facsimile generator at a receiver station go through an acquisition and tracking process which aligns the two signals so that a logical processor can compute the frequency transfer function of the entire propagation path for use in an adaptive, concurrently sent communication signal. The frequency transfer function is conveyed back to the transmit end via a control channel permitting an adaptivity function at the transmit end to influence subsequent selection of communication parameters, among which are typically transmitted data rate, selection of modulation, selection of forward error correcting coding, and selection of frequency band for transmission. The same measurement is conveyed to an adaptivity function at the receive end for use in the communications receiver to select demodulator variables such as gain control, and equalization of amplitude and phase, versus frequency. The adaptivity function also permits interspersing of reverse-direction communications over the same frequency bands in a time-share mode between forward-direction and reverse-direction communication with the measurement signals having to be transmitted in only one direction. An alternate embodiment invention of this type is described which is additionally useful for mobile communications channels. Another variation embodiment is described for pure propagation measurements only, absent conveyance of end-user information.
