A mobile network device moves along a track rail structure of a ceiling-mounted track enclosure. The ceiling-mounted track enclosure further comprises a beam transmission cavity for accommodating a collimated light beam having a prescribed cross-sectional area and having been transmitted into the beam transmission cavity by a free space optical transmitter, without obstruction of the collimated light beam by the mobile network device along the track rail structure. The mobile network device receives, at a selected detection area within the cross-sectional area, a modulated light signal transmitted within the collimated light beam. The selected detection area is substantially smaller than the prescribed cross-sectional area and allocated exclusively to the mobile network device. The mobile network device can move toward an identifiable destination position of the track rail structure by a determined arrival time in response to the mobile network device detecting a movement instruction in the modulated light signal.
