What is IEEE 802.16* / WiMAX* / ETSI HiperMAN*?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

What is WiMAX?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!

• Higher throughput at longer ranges (up to 50 km)– Better bits/second/Hz at longer ranges
• Scalable system capacity– Easy addition of channels maximizes cell capacity– Flexible channel bandwidths accommodate allocations for both licensed and unlicensed
spectrum
• Coverage– Standards-based approach to advanced techniques (mesh, beam-forming, MIMO) to improve
non-line-of-sight performance
• Quality of Service– Connection oriented MAC supports voice and video– Differentiated service levels: E1/T1 for business; best effort for residential
• Cost & Investment Risk– Interoperable equipment lets operators purchase equipment from more than one vendor –
WiMAX-Certified– A stable, standards-based platform improves OpEx by sparking innovation at the network
management layer, antenna layer & elsewhere
