Abstract: A terminal device is configured to perform a method for identifying a target device in a local area network (LAN) comprising a plurality of potential target devices. The method includes communicating in an omni-directional format to obtain discovered devices within the area, communicating in a narrow beam format in a direction of the target device; identifying a first list of a first plurality of devices including the target device; eliminating a device from the first list of devices to create a second list of devices; calculating a distance between the terminal device and each device in the second list of devices; determining a precise distance between the terminal device and the target device using a precise distance measurement method; determine which device of the second list of devices has a distance that compares favorably to the precisely determined distance; and identifying the device ID.
