IEEE 802.16
• The WiMAX ForumTM is a non-profit industry forum, created to grant and certify
compatibility and interoperability among IEEE802.16 based product from different
vendors (equivalent to Wi-Fi for IEEE802.11)
•Works to achieve global acceptance: works with regulators to promote global
harmonization of “WiMAX friendly” spectrum
• Promotes the adoption of IEEE 802.16 compliant equipment by operators of
broadband wireless access systems with marketing activities
•Siemens is a Principal Member in the WiMAX Forum since January, 2004

802.16-2004, 802.16e
Indoor/Outdoor modems
Residential Gateways
Fixed Access
• Indoor / Outdoor
• DSL like service
• Service limited to installed
area
• Device authentication and
authorization only
• VoIP application supported
Portable Indoor/Outdoor
modems
Nomadicity
• DSL like service from
different ‘points of attachment’
• Stationary usage: no BS
handovers
• User Authentication
• Multi-operator roaming
Laptops
Portability
•User authentication
•Stationary or limited
mobility
• Break-before-make BS
handovers
• QoS degradation during
handovers (no VoIP)
• Multi-operator roaming
• Interworking w/o seamless
handovers
•VoIP application
Laptops
PDAs
Full Mobility
• Optimized Make-beforebreak handovers
(latency, QoS, data loss)
• Interworking w/
seamless handovers
(session continuity)
• Optimized low-power
operation
• VoIP service, IMS

Adds:
•primitives for handover
•standard procedure for AAA
Chipset for PCMCIA No handover
Chipset for Centrino Handset
• Intel is the main driver for WIMAX: Integration in Centrino is the disruptive goal
• Present Focus is 802.16d for fixed wireless access (OFDM256 mode)
• Next Step will be IEEE802.16e standard
• Evolution towards portable/mobile application will follow
