Operator A Joint frequency range Joint radio access system Operator B Operator N 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

8. Increasing investment in solutions • Increasing IPR portfolios Chance for consensus building Products and markets in competitive environment Chance for consensus building decreasing Pre-competitive early collaborative research Standardisation in early competitive environment Grade of concept maturity Increased maturity makes consensus building difficult Increasing IPRs portfolios make consensus building difficult IPRs International consensus building at an early stage Source: Siemens AG

9. Mobile and wireless networks and systems • Backbone and access system (wireless and wireline) towards packet-based transmission and service agnostic networks • Multitude of access systems available • Systems will become service agnostic • Content, service and access provision may be in different hands • Value constellation is blurring Spectrum usage may change from today‘s • Sensor, RFIDs and embedded systems for service provision in conjunction with other systems (e.g. health care) FMC • dedicated allocation to • Services will be designed to be supported independent of system technology • Improvement of existing and emerging systems as well as development of new systems • more spectrum sharing and infrastructure sharing scenarios Fixed networks New packet-based protocol to be developed for better support of mobile and wireless links in addition to fixed links Conclusions
