To accurately determine the location of mobile device a multi-phase procedure incorporating mapping and location determination phases is suggested, wherein covered area estimation comprises (i) estimation of base station location, (ii) estimation of transmission range, (iii) estimation of signal map and/or (iv) estimation of area type. The actual location of the mobile device () is determined from the covered area estimation based on relative comparison between the actual environment data and estimations (i)-(iv) and weight numbers resulted from the comparison. During the both phases a database is stored in server () and updated whenever new environment data is received. The vertical position, or 'elevation', of mobile device is further estimated based on vertical level information associated with the covered area estimations during the mapping phase.

Method and system for refining accuracy of location positioning

A security device () is a compact and inexpensive device for monitoring the integrity of closed objects that indicates when the state of a monitored condition inside the closed object has changed. The device () is small-sized so that it can also be placed inside small closed objects, e.g. a briefcase, box, envelope or alike, and that it is inconspicuous to the observer if the closed object is opened. The device () is relocatable inside the closed object. The device () comprises a controller () and associated memory (), a time counter () in connection with the controller (), sensors () communicating with the controller () and arranged to sense changes in conditions inside the closed object and indicating means () communicating with the controller () and arranged to wirelessly indicate invasion against the integrity of the closed object. While the changes in conditions inside the closed object comply with certain predefined conditions the alarm indication can be blocked. The alarm indication of the security device () can also be activated and deactivated externally by means of a remote control or automatically.

Security device for monitoring integrity of closed objects

A method and system for accurately determining the location of the mobile device () is disclosed. In the mapping phase collected reference positioning data and collected cell data are used to map a covered area estimation and in the actual location determination phase the covered area estimation is calculated from actual environment data received through wireless cellular communication network () and possibly but not necessarily from external databases (). The covered area estimation comprises at least some of the following calculations: (i) estimation of base station location, (ii) estimation of transmission range, (iii) estimation of signal map and (iv) estimation of area type. The actual location of the mobile device () is determined from the covered area estimation based on relative comparison between the actual environment data and estimations (i)-(iv) and weight numbers resulted from the comparison. During the both phases a database is stored in the server () and updated whenever new environment data is received.
