Broadband wireless access technologies including wireless personal area networks, wireless local area network, wireless metropolitan area networks, wireless wide area network of four kinds of broadband wireless access technology. ADSL, Ethernet, fiber, FTTP and other popular broadband access technology, analyzes the characteristics of each technique and specific applications, and the development of broadband access technology are compared. Keywords：Broadband Access Technologies; Access Technologies; Compariiso of Various Broadband Technologies 目 录 摘 要 Ⅰ Abstract......................................................
