Introduction
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.
