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.
