Abstract: Folding wireless communication devices incorporate a two-part housing, which includes a first part that is rotatably coupled to a second part. The overall depth of the device is reduced by adjusting the mechanical layout and component placement relative to one another, wherein previously stacked components have been reordered. More specifically, the hinge, the battery, and the communication and control circuitry have been organized so as to be in the same horizontal plane, and so as to not overlap in a vertical direction.
