Wireless Dense Networks:Simple rescaling or change of paradigm?
Jun 6th, 2013 – Madrid, SpainPanelist: 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 hardware / RF technology push (also requires standards)
2. Money invested will eventually come back when somebody finds how to use the technology
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!
SO where is the problem exactly?
• Theoretical capacity is already thereBUT
• 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
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.
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– Sustainable = cost-effective hardware must be simple operation must be energy-efficient
– Efficient operation = continuous optimisation control must be complex
• Solution:– Software Defined Networking!

SDN for DenseNets
• From:– static, vendor-specific, centralised control
• To:– dynamic, open, distributed control
Localcontroller
Regionalcontroller
Core network
Backhauling
Well, life is not THAT easy much research to be done
More realistic viewof the architecture
