2. Recommendations on use of other bands for IMT-2000 • Requirement for roaming and interoperability means that globally harmonised frequency bands will minimise requirements for multi-mode/multi-band terminals • Further studies within ITU, as stated in WRC 03 Resolution 228, will be the basis for additional identification of spectrum for the development of IMT-2000, in particular for rural areas… typically in the 470-600 MHz (cf. UMTS Forum Report 38 “Coverage Extensions Bands for UMTS/IMT-2000 in the bands between 470-600 MHz”) • “Unique” national allocations or mixed band plans will not serve the interest of mobile users and the market as a whole, e.g. 1900 MHz issue in India • Technology Neutrality = open to technologies within an harmonized radio-spectrum band allocation UMTSF Viewpoint on Spectrum UMTS Forum recommends that new frequencies for 3G/UMTS services must be proposed to all operators on a transparent basis and globally harmonised

3. Evolution of Regulation (1)UMTS Forum perspectives and recommendations • The regulatory environment – including the approach taken to spectrum rights – is a critical enabler of success for the mobile sector • A stable regulatory environment provides certainty for investors and enables market players to establish robust business cases. • 3G/UMTS is an evolution of GSM/GPRS/EDGE on network and services aspects; most operators have built integrated 2G/3G offerings (common portals…). The mobile world has to be designed and defined under the form of technical innovations and of new services in an evolutionary framework, and without technological ruptures • Technological developments (e.g. WiFi) are not making regulation redundant: on the contrary, there is a strengthened need for harmonization between regulatory approaches to accommodate the emerging players Transparency and availability of information are key

4. Evolution of Regulation (2)Harmonisation and flexibility are not opposed • Technology neutrality means ‘open to technologies within harmonised spectrum band allocations’ • Harmonised bands ensure economies of scale, roaming, interoperability and access to export markets • Deployment timing adapted to each country’s needs, according to market demand • Importance of harmonising frequency fees – in particular between telecom and other types of services, such as broadcast

5. 3G/UMTS Evolution: basic principles • High Speed Packet Access (HSPA) is the first progressive step toward delivering ‘triple play’ (telephony, broadband and TV) in a mobile broadband environment • Likely acceptance of mobile broadband and mobile triple play will raise the need for evolved UMTS; therefore it is vital that operators ensure the long term competitiveness of 3G infrastructure • The 3GPP RAN long term evolution task force was created at end 2004, notably considering the ‘Super 3G’ proposal of NTT DoCoMo • The proposed RAN architecture, placing increasing functionality within the NodeB, will be based on IP routing with existing 3G spectrum, providing speeds up to 100 Mbps by using channel – transmission bandwidth between 5MHz and 20MHz • 3GPP Evolved UMTS specifications should target availability of commercial products around 2010

10. Conclusions • 3G/UMTS is already a commercial reality with more than 35 million subscribers on 100 networks worldwide • 3G/UMTS uses globally harmonised spectrum and builds on economies of scale of global GSM market (>1.5 billion customers), as well as offering clear future roadmap to higher bit rates via standardisation within 3GPP • With HSPA, mobile operators can significantly boost performance of WCDMA to achieve speeds comparable with Fixed Wireless Access systems (FWA) • FWA systems such as WiMAX present a potentially valuable complement to operators’ pure cellular portfolios, offering high user data rates over shorter distances and operating mainly in license exempt radio spectrum. However they do not replace the unique combination of benefits offered by IMT-2000 systems, that have been designed for full mobility • WiMAX already enjoys significant vendor and operator interest, but, globally harmonised spectrum has not yet been secured and 802.16e specifications for WiMAX with some mobility will not be standardised before 2006, in advance of commercialisation from ’07-’08 • Digital broadcast technologies (e.g. DVB-H) also have the potential to complement operators’ portfolios and create new revenue opportunities • Systems beyond IMT-2000 will appear around 2015, but there is still much time and space for 3G/UMTS evolution towards high speed mobile broadband and services; IMS will offer the platform for 3G evolution and service convergence • The UMTS Forum continues to contribute to the decision-making process

11. Taking the next step… In a world of 6.4 billion people and 2 billion mobile subscribers, how can we broaden the reach of 3G/UMTS? • Ensuring access to harmonised spectrum will deliver economies of scale to industry & directly benefit end users • Lower-cost terminals can make 3G/UMTS relevant and accessible to a greater proportion of the world’s population
