To improve Wake-on-LAN functionality of a device, a Media Access Control address filtering function may be implemented in the device’s Ethernet physical layer block. In accordance with the invention, at least one orthogonal code set is generated based upon orthogonal spreading codes, one of the at least one orthogonal code set is determined as a representative orthogonal code set, and then the order is allocated according to rules determined based upon the representative orthogonal code set. The electrode layer has a smaller surface area than a surface area of the current collecting material.
