Wireless Dense Networks:
Simple rescaling or change of paradigm?
Jun 6th, 2013 – Madrid, Spain
Panelist: Claudio Cicconetti
First things first
I would put my money on:
Change of paradigm
Explanation
• Let’s have a look to the past
• OK, not so much in the past…
Good ol’ GSM
• Launched in 1991
• Skype 2003
• Gtalk 2005
• Twitter 2006
• Whatsapp 2009
UMTS
• Launched on 2001
• iPhone 2007
• Foursquare 2009
• Google latitude 2009
• Instagram 2010
So what?
• The bottom line is:
• Telecom industry used to work this way:
1. See what you can do with state-of-the-art
hard...
BUT what about now?
• Fact #1
– The Internet (= core network) just works
• Fact #2
– Radio access technology is (largely!)...
SO where is the problem exactly?
• Theoretical capacity is already there
BUT
• Actual capacity is not always where the use...
Back to the original question
• We have demands from market/users TODAY
• We have technology supporting those
demands TODA...
Conclusion
(same as opening slide if you have paid attention)
I would put my money on:
Change of paradigm
Any tips on what we could do?
• Goal: deploy lots of access points operating
efficiently in a sustainable manner
– Sustain...
SDN for DenseNets
• From:
– static, vendor-specific, centralised control
• To:
– dynamic, open, distributed control
Local
...
Well, life is not THAT easy 
 much research to be done 
More realistic view
of the architecture

  1. 1. Wireless Dense Networks: Simple rescaling or change of paradigm? Jun 6th, 2013 – Madrid, Spain Panelist: Claudio Cicconetti
  2. 2. First things first I would put my money on: Change of paradigm
  3. 3. Explanation • Let’s have a look to the past • OK, not so much in the past…
  4. 4. Good ol’ GSM • Launched in 1991 • Skype 2003 • Gtalk 2005 • Twitter 2006 • Whatsapp 2009
  5. 5. UMTS • Launched on 2001 • iPhone 2007 • Foursquare 2009 • Google latitude 2009 • Instagram 2010
  6. 6. So what? • The bottom line is: • Telecom industry used to work this way: 1. See what you can do with state-of-the-art hardware / RF  technology push (also requires standards) 2. Money invested will eventually come back when somebody finds how to use the technology
  7. 7. BUT what about now? • Fact #1 – The Internet (= core network) just works • Fact #2 – Radio access technology is (largely!) overprovisioned • IEEE 802.11n: easily 100 Mb/s, can be 300 Mb/s • HSPA+: up to 84 Mb/s • LTE: up to 300 Mb/s • Let’s not even mention LTE-A!
  8. 8. SO where is the problem exactly? • Theoretical capacity is already there BUT • Actual capacity is not always where the user wants it to be (i.e., close to him/her) HENCE • NO NEED for a technology push – the network is already adapting to what the users want NOW  densification of wireless networks
  9. 9. Back to the original question • We have demands from market/users TODAY • We have technology supporting those demands TODAY • UNFORTUNATELY, we just can’t continue to deploy new base stations since that would break the spell  we have a problem TODAY backhauling constraints, control protocols do not scale well, growth is not economically viable, etc.
  10. 10. Conclusion (same as opening slide if you have paid attention) I would put my money on: Change of paradigm
  11. 11. Any tips on what we could do? • Goal: deploy lots of access points operating efficiently in a sustainable manner – Sustainable = cost-effective  hardware must be simple  operation must be energy-efficient – Efficient operation = continuous optimisation  control must be complex • Solution: – Software Defined Networking! www.ict-crowd.eu @FP7CROWD
  12. 12. SDN for DenseNets • From: – static, vendor-specific, centralised control • To: – dynamic, open, distributed control Local controller Regional controller Core network Backhauling
