Wireless Campus of the Future

SURFnet and wireless?!

SURFnet is ahead of the market

– what is ‘being ahead in the

wireless market’?

Facilitator or Innovator? Or both?

Open or Closed ‘User’ Group?

Is ‘the campus’ the place to be to challenge current wireless

paradigms? And what is that challenge?

Wireless Local Loop – never successful in NL

Typically below 1 GHz, quite widespread in rural areas or low-quality

wired infrastructure

Reprise: WiMax in NL (‘wireless DSL’) – pushed out the market by

existing wired infra-providers

Wired infrastructure in

NL is HQ and very dense

Trend in wireless is to provide more bps/m3

more spectrum, more spectral efficiency (e.g. MIMO)most important measure is ‘architectural’, i.e. densification

Note: wired infra is quite static in terms of density …

… when is density comparable?

Traffic needs to be transported from access point to ‘internet’

Wired infra becomes enabler and root of successful roll-out of

next-generation wireless infra

What if trend continues?

From pointless attack (too early) to symbiosis (spot on) to …

Compare with wall sockets – clear development to ‘ambient’

Will it continue, and will it happen at the campus?

“The traffic demand is doubling every year (cf Cisco, Huawei, DoCoMo) whilst available capacity is only doubling every ten years. This gap between demand and supply requires major technological advancement” (Net!Works, 2011)

Is it just more bps/m 3?

More densified architectures lead to new upcoming trends

Interference battle : decrease ‘interfered volume’, high freqs across

(unshielded / static) wired infrastructure

� 60 GHz / THz radio / POF is a partial way out

� transmissions consume area: multi-hop minimizes interfered area

Heterogeneous networking : wifi – 3G/4G/ …, offloading, HetNet

development in 3GPP, 802.11u (MAC enhancement focused on

network selection)

Challenges HetNet:

Inter-cell interference (open / closed user group)

Mobility management

What is the use of LTE femto cells

for SURFnet, in e.g. student

houses? ?

Is it just more bps/m 3?

New spectrum policies / spectrum etiquette and enabling

technologies / cognitive radio:

From command/control to market-based to ‘commons approach’

Role of SURFnet as Innovator: raise the bar, create with

partners incl regulator a new Dutch landmark in wire less

Conclusions

Current cooperation between SURFnet and LTE providers focuses on SURFnet as facilitator …

… providing integrated mobile / wireless access… enlarging the reach and use of ‘eduroam’

Raise the bar! From the scenario analysis in TNO’s report:“SURFnet is approached by the European Commission within the PPP-FI program for ‘capacity building’, together with the other NRENs. By showing a wider ambition (fixed/wireless), the Commission will stimulate a strong role for SURFnet in the ‘smart city’ projects.” – SURFnet as a real innovative mobile player

The Wireless Campus as platform for wireless networ k innovation!
