LBS are a reality the agencies very much interested in now, and everybody thinks it’s a great idea to build their own location database where the most popular way to do this nowadays is to let users do. The new software on one’s cell phones not only tells where one is but also tells their operators where the Cell-ID and Wi-Fi networks are in relation to the users GPS location.
Location-API has one of the biggest databases of Cell-IDs, claiming 6.78 million of them worldwide. This is a huge database that gets updated with a continuously significant flow of positions every day. For the calculation of the Cell-ID and Wi-Fi AP position data of only 100 latest submitted positions is used. If Cell-ID changes or the Wi-Fi spot moves, it will be adjusted automatically after a while.
