WiMAX Forum
• IEEE 802.16 is the MAN technology core standard
• WiMAX is equivalent to Wi-Fi alliance • enabling broadband wireless solutions with lower cost CPE• enabling multiple vendor support
• WiMAX Forum includes leading service, application, component andsystem providers. Working together to define the WiMAX Profile standards.
• WiMAX promotes the interoperability of WiMAX profile based devices
• Not every “802.16” product is “WiMAX”…
• WiMAX Forum has formed: Technical, Certification, Marketing, Regulatory, Service Provider and soon Application working Groups.
• Alvarion has strong leadership role: Board, VP Marketing, CFO, CWG Sect,…

NLOS Functionality
• OFDM Modulation overcomes multi-path and deep fades in parts of the spectrum
• Extended coverage and reach increases market share and revenue
• Easier installation reduces operation & installation costs, enabling for subscriber installed CPEs (“zero install”)
