Five scenarios
The scenarios outline the scope of METIS,
reflect one specific challenge each
Each scenario addresses at least one METIS
overall goal

Telekom Innovation Laboratories 9MOBILE AUGMENTED REALITY
Yesterday
Requirements for service provisioning
Mobile Augmented Reality (AR)
Very small networking and processing time (< 50 ms for data
transmission and analysis)
High update rate (5 - 30 Hz) in order to follow body
movements and changes of viewing direction
Overall data rate (image and context) is 50 kb/s up to 1 Mb/s
and tomorrow
Applications in construction, maintenance, and public
security already under development
Broad acceptance of AR could increase the mobile data
volume by a factor of 2000
Latency requirements might require edge computing.

PRESS RELEASES ON 5G INITIATIVES IN EUROPE
5G mobile and wireless communication systems will
require a mix of new system concepts to boost
spectral efficiency, energy efficiency and the
network design, such as massive MIMO
technologies, green communications, cooperative
communications and heterogeneous wireless
networks. We expect to explore the prospects and
challenges of 5G mobile and wireless
communication systems combining all of the above
new designs and technologies. It is important to
recognize revolutionary technology elements and
more evolutionary approaches which both will lead
to 5G (quote from: Vodafone)
