Location-based Services (LBSs) are mobile services for providinginformation that has been created, compiled, selected or filteredunder consideration of the users' current locations or thoseof other persons or mobile devices. Typical examples are restaurantfinders, buddy trackers, navigation services or applications in theareas of mobile marketing and mobile gaming. The attractiveness ofLBSs is due to the fact that users are not required to enterlocation information manually but are automatically pinpointed andtracked.
This book explains the fundamentals and operation of LBSs andgives a thorough introduction to the key technologies andorganizational procedures, offering comprehensive coverage ofpositioning methods, location protocols and service platforms,alongside an overview of interfaces, languages, APIs and middlewarewith examples demonstrating their usage.
* Explanation and comparison of all protocols and architecturesfor location services
* In-depth coverage of satellite, cellular and localpositioning
* All embracing introduction to 3GPP positioning methods, such asCell-Id, E-OTD, U-TdoA, OTDoA-IPDL and Assisted GPS
* Explains the operation of enhanced emergency services such asE-911
* Identifies unsolved research issues and challenges in the areaof LBSs
This comprehensive guide will be invaluable to undergraduate andpostgraduate students and lecturers in the area oftelecommunications. It will also be a useful resource to developersand researchers seeking to expand their knowledge in thisfield.
