5 Spectrum Management at Crossroads Harmonisation? Continue with harmonisation? Decide on a case by case basis! Change to liberalisation? past present future time Page 5 Feb-07

6 Flexible Spectrum Regulation Liberalization No restrictions on spectrum usage Frequency bands / spectrum are used for economically enhanced applications Potential interference Spectrum Trading Efficient use of spectrum/frequencies New market Spectrum Pricing Economically efficient use of spectrum Continuing incentive towards more productive use of spectrum Page 6 Feb-07

7 Discussion Status: SDR as Enabler for Spectrum Management Changes The recent UK Foresight Program of the Radiocommunications Agency brought a novel perspective on spectrum and its future exploitation In the US, the FCC Spectrum Policy Task Force proposed new approaches to "managing" spectrum (2002) In Japan, the recent Communications Council report on "Radio Policy Vision" paves the way for significant reforms in the future In the EU, work on the policy and regulatory implications of the availability and use of radio spectrum is carried out in the Radio Spectrum Policy Group (RSPG) and in the Radio Spectrum Committee (RSC) respectively Spectrum Reframing strategies, UMTS 900/GSM, ITU Page 7 Feb-07

9 Cognitive Radio Challenges Software Defined Radio principles are the basic platform on which Cognitive Radio can be optimally build Cognitive Radio provide the spectral awareness technology that support dynamic Spectrum Usage Cognitive Radio reflects two main streams: Dynamic Spectrum Allocation (DSA) and Flexible Technology/Standard Usage Cognitive Radio Detection of hidden incumbent systems Sharing with primary spectrum allocation Secondary allocation of Spectrum Interference Management/Minimization (coexistence) Spectrum Sensing Mechanisms Flexible Technology Usage Page 9 Feb-07

12 Liberalisation vs. Harmonisation Liberalisation can lead to 1. more innovation by new radio technologies 2. reduced compatibility and interoperability 3. decrease of value of harmonised spectrum 4. more proprietary radio technologies 5. more intensive use of spectrum 6. less restricted spectrum trading 7. faster innovation cycles 8. more competition on technology level - Harmonisation can lead to 1. more innovation by evolution of existing radio technologies 2. facilitated roaming 3. high value of harmonised spectrum 4. more standardized radio technologies 5. timely reservation of spectrum 6. Limited spectrum trading 7. concentration of research budgets more competition in the market - - Harmonisation and liberalisation in spectrum management are to some extent contrary. But both have their advantages and justifications. Page 12 Feb-07

13 Use Cases for Cognitive Radio in Commercial Implementation Meshed Networks with WiFi or WiMAX: A policy management between operators is needed Use same WiFi technology between cells and operators for easier interference and frequency management Femto Cells in License Exempt Bands A coexistence policy is needed known technologies in macro and indoor environment must be used A license-exempt vision in some bands is efficient and commercial aviable however a certain technology in a certain band is allowed and operators must use the same technology License-exempt is the start for Cognitive Radio Page 13 Feb-07

14 Discussions The feasibility of technology neutrality Is CPC harmonized internationally at one frequency band? The CPC require a separate system. Consequentially it would be always an add-on that brings (only) some more comfort because each terminal should basically also work if no CPC can be received Identifications of bands flexible vs. harmonized Technological Challenges Spectrum and refarming policies SDR implementation Opportunities Efficient use of resources Fast time to market for new technologies Low CAPEX/OPEX: Reuse However the use case for Cognitive Radio and flexible spectrum usage should be carefully treated Page 14 Feb-07
