Candidate bands under discussion in ITU-R WP8F for additional spectrum identification 4400 – 5000 MHz 3400 – 4200 MHz 2700 – 2900 MHz 450 – 470 MHz 410 – 430 MHz 1 GHz 2 GHz 3 GHz 4 GHz 5 GHz f [GHz] 2300 – 2400 MHz 470 – 806/862 MHz In some part bands sharing would be needed – more flexible spectrum usage Not many wideband consecutive bands possible Trade-off between QoS, requirements and complexity Laws of physics to be respected Final system design depending on identified and available frequency bands Source: ITU-R WP8F

Potentially available spectrum for beyond 3G systems may require infrastructure sharing Sharing between different systems for different applications under discussion Depending on available spectrum from candidate bands potentially infrastructure sharing required to support QoS with sufficiently wide carrier bandwidth fair access to spectrum and competition Operator A Operator B Operator N Joint radio access system frequency range

The value chain from research to global products Regulation (WRC, CEPT, NRAs) European R&D Projects (e.g. FP6, FP7 & Eureka) General Research Activities (e.g. universities) National R&D Projects Company Internal R&D Harmonisation-Standardisation ITU, 3GPP, IETF, IEEE OMA, WWRF Products System Solutions Exploratory Work Technologies and Markets Implementation and Deployment The implementation and deployment of systems based on global specifications and standards is following a value chain from basic research national, European and general research activities towards research in the industry in the pre-competitive domain. These research results influence significantly the global standardisation and regulatory process and contribute to consensus building and harmonisation of specifications and standards. This allows the economic exploitation of research results in the competitive domain with economy of scale inter-operable systems and the support of global user and terminal roaming Source: eMobility

International consensus building at an early stage Standardisation in early competitive environment Products and markets in competitive environment Pre-competitive early collaborative research Grade of concept maturity IPRs Increased maturity makes consensus building difficult Increasing IPRs portfolios make consensus building difficult Increasing investment in solutions Increasing IPR portfolios Chance for consensus building Chance for consensus building decreasing Early cooperation in the research phase is the key for international consensus building and harmonisation to prepare future specifications and standards. In the early stage system concepts are immature and IPR-portfolios are not built-up. This is the time window for successful cooperation and the joint development of new systems. If cooperation is starting in the standardisation phase, harmonisation is becoming more difficult due to the transition from the pre-competitive to the competitive domain. In the final competitive phase of product development harmonisation is becoming very difficult, if no common standards are available. Therefore, let’s start cooperation early in research on global basis in the interest of the community. Source: Siemens AG

Mobile and wireless networks and systems Conclusions FMC Mobile and wireless networks and systems Fixed networks Content, service and access provision may be in different hands Value constellation is blurring New packet-based protocol to be developed for better support of mobile and wireless links in addition to fixed links Services will be designed to be supported independent of system technology Systems will become service agnostic Backbone and access system (wireless and wireline) towards packet-based transmission and service agnostic networks Improvement of existing and emerging systems as well as development of new systems Multitude of access systems available Sensor, RFIDs and embedded systems for service provision in conjunction with other (e.g. health care) Spectrum usage may change from today‘s dedicated allocation to more spectrum sharing and infrastructure sharing scenarios B3G is a concept to integrate different access systems on common packet-based system to support user needs in economic and optimal way Different usage scenarios need to be covered mobile in different scenarios wireless DSL – BWA short-range communications PAN, BAN, sensor type systems broadcasting systems fixed networks Licensed and unlicensed frequency ranges Reuse of deployed investment and emerging new systems Support of interworking between different access systems via vertical handover service adaptation New radio access systems are one component of the overall concept Combination of revolution by new technology and evolution from installed base
