发明名称 Determining Approximate Locations of Network Devices That are Inaccessible to GPS Signals
摘要 Methods, apparatus, and computer program products for determining approximate locations of network devices. Information is received concerning last known locations of portable network devices that attach to a network, and used to compute an approximate location of an obscured network device attached to the network. In some embodiments, the last known locations of the portable network devices may be determined using information from GPS satellites. The approximate location of the obscured network device may be used as the approximate location of other stationary network devices connected to the same network.
