It is an object to provide a high ion conductive solid electrolyte which uses organic and inorganic complex compound having water absorption and water resistance and to provide an electrochemical system using the high ion conductive solid electrolyte. The wireless positioning apparatus receives an estimated channel response from a mobile station and compares the estimated channel response with the plurality of channel response patterns to estimate a location of the mobile station. The front crankpin is located in proximity to the front end and the rear crankpin is located in proximity to the rear end.
