Today's society is undergoing change: globalization and the ever-increasing digitalization are changing the world view from possessive to share. "Sharing is Caring" is the creed of the 21st century and brings with it many new services such as car-sharing, cloud computing and their evaluation. The smart city of tomorrow connects, learns and optimizes through an almost unmanageable number of data streams. In the utopia of the "Smart City" even the trashcan communicates with the refuse collection and says exactly when it would be ready to be emptied. However, in the "City of Sensors", we forget the scale that should underlie any innovation: the human scale. For this reason, the master thesis deals with the topic of how modern technology affects the urban way of life and why a networked city should be the goal but a "smart city" should not be implemented by any means necessary. Based on three urban planning scenarios, the Gründerzeit Block, the Superblock of Red Vienna and the Zeilenbau, both outside and inside potentials are shown, which can be fully exploited by spatial densification, mixed use and, in particular, by the support of the Internet. The master thesis is structured into an introductory part which explains the technological prerequisites for a network urbanism and shows already implemented, international examples. In the design part, the urban planning configurations mentioned above are analyzed with regard to their typology and proposals for their activation and shared uses are made.
