information that has been created, compiled, selected or filtered
under consideration of the users' current locations or those
of other persons or mobile devices. Typical examples are restaurant
finders, buddy trackers, navigation services or applications in the
areas of mobile marketing and mobile gaming. The attractiveness of
LBSs is due to the fact that users are not required to enter
location information manually but are automatically pinpointed and
tracked.
This book explains the fundamentals and operation of LBSs and
gives a thorough introduction to the key technologies and
organizational procedures, offering comprehensive coverage of
positioning methods, location protocols and service platforms,
alongside an overview of interfaces, languages, APIs and middleware
with examples demonstrating their usage.
* Explanation and comparison of all protocols and architectures
for location services
* In-depth coverage of satellite, cellular and local
positioning
* All embracing introduction to 3GPP positioning methods, such as
Cell-Id, E-OTD, U-TdoA, OTDoA-IPDL and Assisted GPS
* Explains the operation of enhanced emergency services such as
E-911
* Identifies unsolved research issues and challenges in the area
of LBSs
This comprehensive guide will be invaluable to undergraduate and
postgraduate students and lecturers in the area of
telecommunications. It will also be a useful resource to developers
and researchers seeking to expand their knowledge in this
field.
Axel Küpper received a diploma in computer science in 1996 and his Ph. D in 2001 from Aachen University of Technology, Germany. Since 2001 Küpper has worked as a research assistant at the Chair of Communication Systems and Computer Networks of Ludwig-Maximilians University Munich. His research activities focus on the fields of distributed systems and mobile communications. Küpper has carried out several research projects about location and context awareness and published approximately 30 reviewed papers.
