2 2/6 Mobile WiMAX leads the way to wireless broadband access With Mobile WiMAX, the communications industry is another step closer to offering mobile broadband Internet access anywhere. We re sure of the success of WiMAX because of the sheer weight of support that the technology carries, with widespread and active co-operation across industries. WiMAX will enable you, the operator to provide cost-effective broadband wireless access for hundreds of users from each base station. You can offer both mobile and fixed services by deploying networks based on Mobile WiMAX. 1.1 Mobile WiMAX- a key differentiator Operators aiming to offer Mobile WiMAX will find synergies with Nokia Siemens Networks, as we fully understand mobility and the demands that mobile access makes on WiMAX networks. We can offer end-to-end solution, from user devices, business consulting and infrastructure, right through to turn-key deployment and even managing the service on behalf of the operator bringing many advantages to operators deploying Mobile WiMAX. Deploying Mobile WiMAX can be a key differentiator and will allow you to make your mark in what will be a crowded market. 2. Why choose WiMAX? WiMAX is an essential element in achieving the wireless communications industry's aim of economic broadband access over a wide geographic area. Fixed WiMAX access is likely to dominate early deployments, with Mobile WiMAX becoming more prevalent as devices become available and the market evolves. Mobile WiMAX will bring personal wireless broadband access on the move, beyond the home and office. 2.1 Creating an extensive WiMAX ecosystem A compelling reason for deploying WiMAX is the structured and extensive ecosystem that is being created to support the technology. Device vendors, infrastructure manufacturers, chipset makers, system integrators, operators, applications developers and other players are all focused on making WiMAX a success.

3 3/6 The IEEE (The Institute of Electrical and Electronics Engineers, Inc) has been developing and will continue to evolve the radio interface standards that support WiMAX. Encouraged by this work, infrastructure vendors are designing and manufacturing IEEE-compliant network elements such as base stations and the necessary core network devices. 2.2 From infrastructure to devices Meanwhile, system integrators have already entered the market and are working with manufacturers to deploy WiMAX technology and ensure it provides the high service levels that the market demands. Encouraged by the large business potential, chipset makers have also backed WiMAX and are promoting its use worldwide. Similarly, device manufacturers are using WiMAX standards to develop innovative customer premises equipment (CPE) and other end-user devices like PCMCIA cards and handheld devices. 2.3 The importance of available spectrum Yet all this effort would be futile without available radio spectrum, which is a scarce resource in many regions. Authorities around the world have recognized this need and are allocating and controlling frequency bands for use by WiMAX operators and managing the use of adjacent spectrum, such as cellular and WiMAX. 2.4 Technology choice is linked to spectrum allocation The first WiMAX deployments are likely to be in the 2.5 GHz and 3.5 GHz licensed bands, with some in the 5.8 GHz unlicensed band. Licensed bands give stability and excellent service quality, particularly in dense urban environments. The lower frequencies typical of licensed spectrum also provide better coverage with fewer base stations, which helps to reduce deployment and operational costs. 3. WiMAX use cases We at Nokia Siemens Networks believe that WiMAX will first be deployed to: 1. Extend broadband Internet access to rural areas or areas impractical to reach with DSL wires 2. Add mobility to existing fixed broadband services 3. Provide wireless broadband services and replace fixed unbundled last mile access with the operator's own wireless infrastructure

4 4/6 Fixed WiMAX Internet access is the early mainstream revenue generator for operators and other service providers. However, Mobile WiMAX will provide a much wider choice of applications. Fixed DSL replacement/complement The first commercial WiMAX deployments will provide broadband access to remote regions and to complement DSL in dense urban areas. Many Broadband Wireless Access (BWA) deployments have already focused on rural areas and this trend will continue with WiMAX technology. Complementing DSL In suburban areas, DSL has sometimes been unable to provide the high speeds that residential users demand. Small and medium sized businesses are also often underserved in many areas. WiMAX has great potential to solve these challenges. WiFi backhaul is highly cost-effective Although WiFi hotspots are cost-effective to deploy, they still need costly backbones to link them to the public network. Using WiMAX to provide this backhaul could significantly reduce hotspot costs and even bypass the need for WiFi altogether with easy to access WiMAX hotzones. Nomadic mobility for access on the move Mobile WiMAX will complement WiFi, filling gaps between hotspots and providing so-called nomadic mobility. This allows users with laptops or other devices to stay connected while traveling between offices. 4. A strong WiMAX industry ecosystem is emerging A successful Broadband Wireless Access business will depend on a stable and comprehensive ecosystem. The three key elements to building the WiMAX ecosystem are good standards, widely available devices and crossindustry cooperation. 4.1 Well-developed standards The WiMAX Forum is encouraging the take up of WiMAX by establishing and promoting the WiMAX brand. The Forum also undertakes network architecture and related profile definitions. The two IEEE standards behind WiMAX are IEEE (Fixed WiMAX) and IEEE (Mobile WiMAX) which extends the IEEE standard to include mobile wireless broadband at walking pace, so-called nomadic mobility. This standard will also support true mobility.

5 5/6 If you are an operator focusing on mobility, you will need to deploy WiMAX in accordance with IEEE This will also allow you to provide fixed access. On the other hand, operators providing fixed services have little incentive to upgrade to IEEE , unless they plan to add mobility into their service portfolio. Available devices (Home CPE, PCMCIA Cards and Embedded Modules). Interoperable devices need to be widely available to meet the differing and growing needs of consumers and business users. Customer premises equipment (CPE) will first be installed professionally with an outdoor antenna. These will be followed by self-installable indoor CPE. PCMCIA cards will give laptop users nomadic mobility. Personal digital assistants (PDAs), Internet tablets and smartphones with Mobile WiMAX will become available as WiMAX access becomes more universal. 4.2 Cross-industry cooperation Cooperation on WiMAX extends across the industry. The expertise needed to evolve the ecosystem is already well developed and in place. Major groups are investing in the development of chipsets, devices and other fundamental components, while smaller players are working together to provide products such as antennas and other infrastructure components. Good availability of the technology will help to accelerate the take up of Mobile WiMAX services by users. 4.3 A full ecosystem from day one Most manufacturers are likely to develop and launch products at about the same time. Consequently, you will have a superb choice of OEM equipment available, roll out will be faster and deployment will be more reliable. CPE products that are well developed and can be installed by the users themselves will also help to minimize operators' OPEX and technical support costs. 5.

We believe that mobile WiMAX is likely to appeal most to operators without cellular spectrum allocations, but who want to offer mobile broadband in their portfolio. These organizations may have limited experience of deploying and operating wide area mobile networks and will need a technology partner that understands the demands that mobile access makes on WiMAX networks. Nokia Siemens Networks knows how to roll out and support large, commercial, single vendor and multivendor networks. Our services, backed by experienced people in more than 150 countries, cover the planning, building, optimizing and maintenance of networks; integrating user services with the network; and even managing the service on behalf of the operator through managed services. Our long experience of deploying and operating wide area mobile networks makes us the technology partner of choice for many operators. 5.3 Supporting the mobile broadband future Having mobile WiMAX in our portfolio underlines our support for a multiradio future, giving you the flexibility to choose different technologies as they evolve. We have a detailed roadmap for the evolution of network technologies that will meet users demands for higher volumes of mobile data, comparable with today s fixed networks. WiMAX offers wireless access as an alternative to fixed access, bringing broadband service to areas without DSL and extending DSL service with mobility. WiMAX technology offers broadband wireless opportunities for operators with no WCDMA 3G license or spectrum, while Long-Term Evolution (LTE) provides the best evolution path from GSM and WCDMA/HSPA to future networks and services. The choice of radio technology is governed by each operator s current network, spectrum assets, and voice strategy.
