12 Worldwide Interoperability for Microwave Access The purpose of WiMAX is to promote deployment of broadband wireless access networks by using a global standard and certifying interoperability of products and technologies. Support IEEE standard Propose and promote access profiles for their IEEE standard Certify interoperability levels both in network and the cell Achieve global acceptance Promote use of broadband wireless access overall WiMAX should become for what WiFi has become for BoD: Intel (chair), Alvarion, Proxim, Fujitsu, Airspan, Aperto, WiLAN Current activities: Marketing Development of system profiles and PICS proforma, Test Suite Structure and Test Purposes specifications and Abstract Test Suite specifications for the 256-point OFDM mode of (equiv. to ETSI HiperMAN) Com MN SM Communications 12

13 WiMAX needs spectrum Current focus of WiMAX is on Fixed Wireless Access based on IEEE (initially OFDM-256, later SOFDMA) aimed for the following frequency bands /3800 MHz (available in many countries, licensed) MHz (license exempt in US, licensed in other countries) MHz (MMDS, aimed for IMT-2000 extention in Europe) WiMAX is pushing towards portable/mobile applications introducing sofdma & handover in IEEE /802.16e providing mobility support to fulfill requirements of Sprint, Nextel and Korean s HPi (High-speed Portable internet) initially aimed for the frequency bands MHz (Korea) MHz (Sprint, Nextel in US) mobile spectrum in Europe is tied to IMT-2000 technologies, may change in the framework of technology neutral assignments. WiMAX is blurring the differentiation between fixed and mobile. Com MN SM Communications 13
