1.1.6. Summary

In this Unit we gave a basic introduction to Location Services:

• We showed that LBSs have its roots in GIS technologies, communication technologies and the Internet containing possibly information we are looking for.
• We made clear that LBS's consist of five basic components:
  1. Mobile Devices
  2. Positioning
  3. Communication Network
  4. Service Providers
  5. Content Providers
  whereas one can group the last two into one component. These components will describe in more detail in the following sections and lessons.
• Apart from the components we gave a number of keywords which carry on to questions we should consider if we want to analyse mobile applications.
• Finally we explained how push and pull services can be distinguished. Pull services sent information on user interaction (asking for the next restaurant) and push services deliver information without user interaction (advertisement in a shopping mall, weather warning).
