Determining approximate locations of network devices that are inaccessible to GPS signals
First Claim
1. A computer program product for determining approximate locations of network devices, the computer program product comprising a computer readable medium having computer readable program code embedded therein, the computer readable program code comprising:
- computer readable program code configured to receive information about last known locations of portable network devices that attach to a network;
computer readable program code configured to compute an approximate location of an obscured network device connected to the network, which obscured network device is not one of said portable network devices that attach to the network, using the last known locations of the portable network devices; and
computer readable program code configured to determine whether to accept a last known location of a portable network device for use in computing the approximate location of the obscured network device;
wherein the computer readable program code configured to determine whether to accept a last known location of a portable network device further comprises computer readable program code configured to compare the last known location of the portable network device with location information computed from a plurality of last known locations of other portable network devices which have attached to the network.

Abstract
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.
