TPositionAreaExtendedInfo is a specialised area class and provides detailed information about the match between the current network information and the network information related to a known position.
In the future the class may be extended to provide information about a match between other available location information (e.g. WiFi MAC address).
In order to provide a user with simplified area information, the match between the two network information should be translated into a area information supported by the TPositionAreaInfo type.

|| Mobile Country Code | Mobile Network Code | Location Area Code | Cell Id | Area ||

|| 1 | 1 | 1 | 1 | EAreaCity ||
|| 1 | 1 | 1 | 0 | EAreaRegion ||

Please note that the conversion of the Cell Id match assumes the worst case scenario, where cells are big (e.g. tens of km radius). In centres of big cities the cell sizes are normally much smaller, taking the area down to the District or even Street level.
