• Location defines context, like time and identity.
– Managing location information implies introducing context awareness
• Location awareness was limited by technology constraints until
recently.
– New devices, pervasive internet acces and the emergence of e.g.
sensor- based networks make it possible to address the “where” in
general terms, independent of the surrounding environment.
• It is made increasingly possible by location and sensor services,
and in general by the increasing adoption of ubiquitous computing.
• Micro geography emerges in addition to the more traditional macro
geography > continuous location awareness
