The document discusses wireless broadband standards including IEEE 802.16 (WiMAX), ETSI HiperMAN, and their applications. It notes that these standards enable high-throughput, non-line-of-sight wireless broadband connectivity for various uses from residential to backhaul. It also describes the WiMAX Forum's role in promoting interoperability between compliant systems through certification.

2. What is IEEE 802.16* / WiMAX* / ETSI HiperMAN*? ETSI HiperMAN and IEEE 802.16 represent a GLOBAL standard for a wireless broadband access akin to Cable, DSL and Ex-level services Designed from the ground up for outdoor, long range, carrier class applications High throughput, non line of sight propagation, scalability for up to 1000's of users, QoS Supports both licensed and license-exempt spectrum Applicable in many markets – from dense urban environments to rural areas Where there is no existing or poor wired infrastructure IEEE 802.16e extension enables nomadic capabilities for laptops Broadband connectivity beyond hot spots Wi-Fi and WiMAX are complementary WiMAX* is to 802.16 as Wi-Fi* is to 802.11 * Other brands and trademarks are property of their respective owners

5. What is WiMAX? Ensure interoperability of IEEE 802.16* and other interoperable (ETSI HiperMAN*) systems Equivalent in purpose to Wi-Fi Alliance for 802.11 Develop Conformance Test Specifications Two year, multi-company process to develop test suites Based upon ISO/IEC 9646 processes System Profiles correspond to market-driven usage modes e.g., license exempt at 5.x GHz, licensed at 3.5 GHz, etc. Set up certification labs for testing Host interoperability events Conformance does not equal Interoperability Provide WiMAX-Certified stamp of approval * Trademarks or servicemarks are the property of their respective owners. WiMAX members represent over 75% of current 2-11 GHz BWA equipment sales!

6. Why has BWA not taken off? Pre-Standard: Proprietary, vertical solutions No volume silicon market Service Providers System Design & Architecture Custom MAC Custom Radio Custom, 802.11 or DOCSIS PHY Network Software System Integration Equipment Mfrs Focus Post-Standard: Equipment interoperability Economies of scale Superior price/performance Service Providers Equipment Manufacturers Volume Integrated MAC/PHY Silicon Solutions Volume Radio Supplier Network Mgmt Software Supplier System Integrator Equipment Mfrs Focus* * Varies by equipment mfr. Some will still do their own S/W and SI.
