An embodiment of the present invention is directed to an authorization and access control system for a venue or a geographic region comprising a plurality of venues. In the spreading code synchronization method according to the present invention, a correlation is first detected between a received signal and a common short code, and a received timing of a scrambling code mask of a handover destination cell is detected based thereon. Alignment of a pattern on a wafer with a chuck is performed before the chuck is mounted on each fine adjustment stage. The light reflector is disposed on the package and corresponds to the LED chip to alter the light direction radiated from the LED chip. The authorized codes are selected from a larger set of available codes.
