In essence LBSs are services that are using potential and capabilities of modern mobile devices, positioning technologies and mobile networks to deliver to the user value added information or service based on his location. The main value of LBS for users is that they do not have to enter location information manually but it is automatically collected (with positioning technologies) and used to generate personalized information.
