A method of manufacture of an electronic substrate, having a process of embedding electronic components in a substrate, and a process of ejecting liquid droplets containing a conductive material, to form a wiring pattern connected to the external connection electrodes of the electronic components embedded in the substrate. The high resistance state for the reference array is a \u201cpartial reset\u201d state having a minimum resistance less than that of the high resistance state for the memory array. An indoor base station and indoor network controller provide protocol conversion for the unlicensed wireless service into a standard base station controller interface of the licensed wireless service. A first polarizing plate is attached on an outer surface of the first substrate. Also, the filtering can be performed through parallel processing without multiplication and division, so that the complexity of hardware can be reduced.
