Keynote at the FP7 CROWD (www.ict-crowd.eu) workshop in L'Aquila, January 14, 2014

1. 5G networks of the future:
Evolution or revolution?
CROWD Workshop
Jan 14, 2014 - L’Aquila (Italy)
Claudio Cicconetti

2. Agenda
1. Challenges: today and tomorrow
a.k.a. why we need 5G
2. Innovations with potential to address them
a.k.a. what 5G might look like
This talk will be only about network architecture
advances. Of course, future network research
is also active on physical layer aspects!

5. New challenges
Lots of smart phones
+ flat billing
+ decreasing revenue per bit
= a big headache
BUT
THAT’S NOTHING!
CROWD workshop - L’Aquila (Italy) - January 14, 2014 - Presenter: claudio.cicconetti@intecs.it

6. Challenges (tomorrow)
Massive Machine Comms
Machine != human
₋ many more devices (10x-100x)
₋ very long battery lifetimes (> 5Y)
₋ low-cost devices (< 1€)
₋ small payloads (few bytes)
₋ fast setup (few 10’s ms)
₋ low latency (< 1 ms)
₋ what else?
