A computer, media player, remote control or other device is configured to determine its relative location within a home, office or other given environment based upon the reception and/or sensing of wireless network signals and/or other electromagnetic signals emitted by other devices present at any time in the environment. The device receives wireless signals from one or more wireless signal sources, and determines a parameter (e.g., signal strength) for the signals received from each source. The location of the portable device within the environment is determined based on the determined parameters. The location may be used for any purpose, such as adjusting a setting on the portable device, identifying another device to be controlled by a portable remote control, or the like.
