Abstract:
1. A method of locating a first device for wirelessly communicating with a second device relative to each other, the method comprising a) providing at least one light source for generating at least one light beam; b) locating the at least one light source on the first device having regard to its appropriate orientation relative to the second device; c) defining a set of range criteria for acceptable locations of the first and second devices relative to each other with a view to acceptable wireless transmission conditions; d) defining a set of beam criteria for the at least one light beam corresponding to the set of criteria for acceptable locations of the first and second devices relative to each other; e) directing the at least one light beam from the at least one device towards the second device; and f) moving the first and second devices relative to each other, substantially along a direction of the at least one light beam until the two devices are within the predefined acceptable locations as determined by the beam criteria; wherein the light source is located on an outer surface of the first device relative to an antenna of the first device for wirelessly communicating with the second device in such a way that the quality of the wireless transmission is optimized when the light from the light source is directed towards the second device.
