A host for setting a power control mode in a wireless communication system, and a method thereof, are provided. An optical transmitter having SBS suppression according to the present invention includes a signal generator that generates a SBS suppression signal. The method also includes configuring a packet forwarding module such that the packet forwarding module implements a second network rule, and receiving status information from the virtual network switch module and status information from the packet forwarding module. The Fresnel lens array, which converges the light to be nearly collimated, enhances the harvest of the available flux thus increasing the system efficiency and providing a system that gives the illusion of having an image at infinity. The classification system selects a classification associated with the classified images that are most similar to the target image as a classification for the object of the target image.
