Location-Based Services [PDF]

open access: yes, 2011
This chapter provides an overview of location-based services and insight into the pivotal importance of location-sensitivity to the success of wireless data services. This chapter argues that mass-market adoption of wireless data services will only occur if these services enhance productivity and/or convenience for end-users; transforming novelty into ...
