Spectrum Utilization between 0 and 6 GHz
Motivation<br />
• Trend: Increasing growth of mobile traffic<br />
7<br />
• More than 5 billion mobile phone users today…and growing at a startling rate<br />
• “7 trillion wireless devices serving 7 billion people in 2017” – Wireless World<br />
Research Forum<br />
• “Mobile Internet traffic handled by mobile operators will grow from 7 billion<br />
megabytes worldwide [in 2008] into 63 billion megabytes in 2013 (CAGR 54%)”<br />
– Informa<br />
• Trend: Regulators allowing secondary spectrum access<br />
• FCC opened door for TV White Spaces in USA<br />
• CEPT and several administrations are getting active<br />
• Active discussion predicted on regulatory measures in the 2012 World<br />

Other challenges<br />
• Usability: how to hide increasing complexity?<br />
• Sustainability: how to provide more in a sustainable way?<br />
• Security and trust: with more decentralization and increased dependency on<br />
ICT and wireless?<br />
• New challengers from other industries and from other economies: How to be<br />
the winner in the new ecosystem?<br />
• How to win in new application areas?<br />

Liberating Spectrum to Enable New Opportunities<br />
<strong>Cognitive</strong> <strong>Radio</strong><br />
Empowering a new realm of devices and services<br />
through optimized connectivity. The world is<br />
moving towards a new era where mutuallyconscious<br />
intelligent devices leverage awareness<br />
of environmental circumstances and user needs<br />
to determine how to communicate on the fly via<br />
dynamic spectrum use for improved connectivity<br />
and capacity.<br />
Research is centered in Helsinki, Finland, including<br />
at the Otaniemi lab, and is focused on:<br />
9<br />
• Methods for flexible spectrum use<br />
• Novel ways of sensing the radio environment<br />
and location<br />
• Distributed networks that intelligently cooperate<br />
• Low power flexible implementation of radio<br />

• Hears and sees<br />
• Knows its status and the environment<br />
• Understands needs via applications<br />
• Discusses with other radios<br />
• Discusses with databases<br />
• Might cause interference<br />
• Prevention of harmful interference<br />
• Expects politeness<br />
• Essential challenges outside traditional radio technology!<br />

and mobile wireless services<br />
• Possible new ways compared to spectrum use today:<br />

• Wild West: Decision-makers<br />
optimize their own situation, not<br />
taking into account any interests of<br />
others<br />
• Cooperation: Decision-makers<br />
optimize their own situation, while<br />
taking into account the interests of<br />
others<br />
• Collaboration: Interacting decision<br />
makers to optimize their<br />
performance, this is based on<br />
active/explicit communication<br />
between the decision-makers<br />
• Standardization ongoing in IEEE<br />
802.19 and in ETSI RRS<br />

From wide area to local optimization<br />
1G: Analogue cellular systems (AMPS, NMT, etc.)<br />
2G: Transition to digital (GSM, TDMA, CDMA)<br />
3G: Fusion of voice and data (WCDMA, CDMA2000)<br />
4G: Performance extremes in wide area, more flexible<br />
bandwidth and spectrum deployments, flat network<br />
architecture (3GPP LTE)<br />
Future trend: <strong>Cognitive</strong> <strong>Radio</strong><br />
• The research frontier in wireless<br />
• Changing the rules on how spectrum is being used<br />
Initial steps with this technology are about to be<br />
taken on the U.S. TV White Space frequencies<br />
that recently were made available by the FCC<br />

Status tomorrow<br />
• Finland is known about wireless solutions that are intuitively easy to use –<br />
things just happen<br />
• Finland has attracted even more world top level wireless research &<br />
development & business activities<br />
• Finland has applied our wireless talent successfully to new business sectors<br />
• Despite the growing role of wireless, energy consumptions is sustainable<br />
