2. What is 5G..
• There is no consensus on what « 5G » is at the
moment. Different parties identify it in a way that
suits their needs.
• METIS, the EU funded project, defined «5G » as
technology that supports
 1000 times higher mobile data volume per area
 10 times to 100 times higher number of connected
devices
 10 times to 100 times higer typical user data rate
 10 times longer battery life
 5 times reduced End-to-End latency

4. Beyond LTE Schemes
 Beyond LTE: (Long Term Evolution)
 An operating point where the number of serving antennas is 10 times
the number of active users.
 Is flexible in the deployment through a modular “lego” type network.
