WiMAX Forum
• Didirikan pada bulan April 2001,terdiri dari pemimpin besar dari industri komunikasi dan komputasi untuk mendorong sebuah platform umum untuk penyebaran global dari layanan nirkabel pita lebar berbasis IP.
• WiMAX Forum akan mengeluarkan sertifikasi berbasis “conformance” dan interoperabilitas produk dalam standar kompatibel IEEE 802.16, ETSI HiperMAN dan lainnya

ConclusionQuote from “WiMAX Forum”
• The WiMAX technology continues to evolve with the WiMAX Forum’s approval of the Release-1 mobile WiMAX system performance profiles based on the 802.16e-2005 amendment. With OFDMA, mobile WiMAX can meet the stringent requirements necessary for the delivery of broadband services in a challenging mobile environment.Performance simulations show that mobile WiMAX provides superior throughput and spectral efficiency compared to planned 3G CDMA-based enhancements, EVDO and HSPA. These advantages will provide operators with added network capacity for the support of value-added services with fewer base stations than alternative approaches thus resulting in lower network capital and operating costs.
