摘要: A software application installed on a mobile device periodically measures parameter and records it along with the position associated measurement. These data are transmitted to repository database, from which all or part of set can be retrieved based filters applied by users automated software. In one embodiment, may cellular signal strength, allowing in areas no useable display strength as map find location where phone call placed. Parameter downloaded database onto device's internal memory such that accessed, filtered, displayed without need connect internet.
