The basic components of an LBS: User, Communication Network, Positioning, Service Provider and Content Provider

For providing and using LBS four main components are needed and have to be combined. A LBS is usually accessed via a mobile electronic device. This device, or mobile computer terminal, should be the only point of contact between user and LBS. All other components, especially the technical ones like positioning and data communication, are usually yielded and should work without knowledge of the user. If the user wants to use a location based service different infrastructural elements are necessary. In the figure the four basic components Mobile Devices, Positioning, Communication Networks and Service & Content Providers.
This lesson shows the technical aspects of the LBS components mobile devices in the first unit, of positioning and communication networks in the second and of service & content providers in the two remaining units.
