Why does ADnota album use GPS data and Cell ID/LAC?
GPS reception is not always available. Indoors, in adverse weather conditions, or close to buildings or other obstacles, the GPS signal may be too weak for proper decoding. The Cell ID and LAC are supplied by the mobile phone (GSM) network. They are available whenever the phone is logged into the network. However, location search using Cell ID and LAC have some drawbacks: in a crowded area a cell covers usually a small area, in a rural area it may cover an area with a radius of more than 10 km. In a given position, more than one network cell may be available. The assignment of a specific cell depends on many factors, such as the network load. Further, the network operator may change the ID assigned to a cell, or install additional cells. Finally, the cell ID depends on the network; each network uses its own cell IDs. The sorting function used by ADnota album operates on GPS or Cell ID/LAC data. If both datasets are available, a proprietary algorithm merges the GPS and the network data.
