A distortion correction device performs pre-processing on an input image data of a double page spread document or the like and produces an edge image. The method further comprises selecting a group of active mobile stations by obtaining at least two active mobile stations with a closest angular distance of all possible pairs of active mobile stations and assigning a single streaming beam to the group of active mobile station, if the number of active mobile stations is bigger than the first threshold. The proxy device may establish a remote access connection to the network before or after receiving a request from the IP enabled communication device to communicate to or via the network. The pad is electrically connected to the component.
