WiMAX technology can also run Voice over IP phones

Voice over IP meets WiMAX - net phoning on wireless phones. WiMAX will offer wireless users large bandwidth pipes that can run their wireless laptops and Voice over IP phones over the same IP network. Imagine if you can make flat rate Voice over IP phone calls all over the world while surfing your web on a wireless laptop. Combing WiMAX and VoIP will make cell phone infrastructure and services obsolete.

"WiMax, a technology standard that will provide broadband Internet access over many miles of coverage, is expected to make a big splash when services emerge in 2006 or 2007. That's because WiMax could become a third option for broadband access, challenging cable companies and DSL providers.

While high-speed data access is considered a driving force behind WiMax's consumer appeal, service providers must bundle features such as VoIP--voice over Internet Protocol--to make enough money for survival, according to a study conducted by market researcher In-Stat/MDR."
