Location-Dependent Data Access and Queries

Abstract

Location-dependent data access technology will create a new family of services in mobile telecommunication systems of the near future. This technology is based on positioning, communication over various protocols, and spatial databases. Location-dependent applications will be used in many fields such as emergency services, information services, and financial services. This chapter intends to present the infrastructure that makes it possible to create such services, and provides an insight on key application development issues. The focus is on location information access as the latest achievements of this research field are presented.
