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

* Other brands and trademarks are property of their respective owners

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!

802.16 and HiperMAN: Designed from Ground Up for the Outdoors802.16 and HiperMAN: Designed from Ground Up for the Outdoors

• 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
