The electrolyte membrane of the present invention is an electrolyte membrane having ionic conductivity that includes a base material and organic molecules having ion exchange groups, wherein the organic molecules are chemically bonded to the surface of the base material to form an organic layer, and ions are conducted via the ion exchange groups in the organic layer. Transceiver architectures according to embodiments of the present invention can be designed to have a single inputoutput for both FDD and TDD based standards. The WCD, responsive to the first auto-location trigger signal, operates in an auto-location mode.
