1.4.6. Summary

This unit presented on one hand the processing chain of a service request and on the other hand some basic knowledge on the five components of LBS. Considering the different components you should know

• that we can distinguish between single and multi purpose devices and further be able to list some device types, e.g. mobile, toll box, PDA, navigation unit;
• that networks can be classified with respect to the area of coverage and that we distinguish between WWAN, WLAN and WPAN;
• that the location of a mobile user can be determined using either network-based positioning or terminal based positioning methods. Further you should remember that the basic principle of position calculation is based on the intersection of distance-circles around base station;
• that data for LBS applications may be classified into purpose specific and general data. And you should be able to list some data type - e.g. yellow pages, topographic data, road data or shopping mall information.
