    摘要: Location position information of a mobile device utilizing Wi-Fi, FM, AM, television transmissions(s), other radio transmission(s), electromagnetic, acoustic, or other signals received from base stations or access points. The position information can be provided through a Web service and/or locally on a mobile user device. The position information can be provided with a certainty and/or uncertainty probability percentage or other perceivable means for the user to determine the expected accuracy of the location information. Also provided is a means for updating base station information to include newly detected base stations through information from a plurality of user devices, wherein each user device is given a reliance factor. User devices that have a low reliance factor are disregarded and/or scrutinized to determine accuracy prior to such information being utilized to update information. Functioning of the system can be improved through analysis of usage data and/or the additions to the database.
