Study On WiFi And Wimax Of Broadband Wireless

In recent years, Wi-Fi and WiMAX develop like a raging fire . Wi-Fi expand rapidly in the market of the notebook PC . Now , Wi-Fi also sets foot in embedded fields, such as mobile phone . Wi-Fi becomes a major wireless technology to construct digital family and digital enterprise . WiMAX's main standards have identified one after another . WiMAX's interoperability testing has begun . Many manufactures are pushing WiMAX to realistic usage actively. The fixed WiMAX networks have deployed in 2006 . Until 2007 and 2008 , WiMAX will embed in handset devices with the disposition of mobile WiMAX networks . WiMAX will coexistenc and integration with 3G , HSDPA and Wi-Fi . It's possible to ramble in seamless broadband surfing in spite of anytime and anywhere.Therefore, it's urgent to solve some problems, such as what operations should carry on and what applications should use based on Wi-Fi and WiMAX..This paper through marketing and usage scenario research of WiMAX and Wi-Fi provided suggestion ideas to China even global broadband wireless development.The full paper is divided into five parts:The first part, author holistically described the broadband wireless access technology.The second part, author started from the concept,characteristics and development process to described broadband Wireless Access to the Wi-Fi and WiMAX technology. Author also give a WiMAX,Wi-Fi and WiMAX,3G network suggestion.The third part, author specially researched the application of Wi-Fi, including Wi-Fi usage scenario and the industry usage.The fourth part, author researched the application of WiMAX. Author from the market perspective researched the application of WiMAX scenario, from the technical perspective researched the main application of WiMAX technology, including the WiMAX cited examples of the application.The fifth part, author talked about the Wi-Fi and WiMAX application in the foreign country and in domestic. Author mainly talked about the domestic application of the Wi-Fi and WiMAX on telecommunications industry.Although WiMAX is a hot topic, but its application has yet been devoted to the discussion and research. This is the greatest achievement of this gap in domestic, can provide some ideas for the development of the domestic WiMAX.
