Need more wireless capacity?
• Today’s 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 what do we need?
• Add more and more base stations, esp. where capacity is needed:– Crowded public spaces– Residential buildings, offices– Events, fairs– …
What we get

Densification of wireless access networks
From macro-cell only

Summary
• 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 because we have issues:1. high CAPEX/OPEX €€€2. interference3. backhaul4. signalling

Project overview
• Connectivity management for energy optimised wireless dense networks– Start: 1/1/13– End: 30/6/15– Total cost: 4,460 k€– Total funding: 2,978 k€– Total effort: 443 PM

Goal
To enable sustainable deployment of very dense and heterogeneous wireless networks
sustainable = cost effective + energy efficientvery dense = 1000x compared to currentdensity (in users/sqm vs. users/BS)heterogeneous =
+ diverse range (macro vs. pico vs. femto)+ diverse technologies (LTE vs. WiFi)+ diverse deployments (planned vs. unplanned)+ diverse backhaul types (optical vs. wireless)

How is this done?
• Software Defined Networking =– Base stations reconfigurable via open interfaces
• SDN OpenFlow SDN

Roadmap
End of 2013• Architecture final• Preliminary solutions• Numerical / simulation
analysis
End of 2014• First public release of CROWD
controllers• Final solutions validated with
stand-alone testbeds• Initial results from integrated
testbed
June 2015• Final demonstrator ready• Full results available
