Research And Implement Of Wireless Access Multimedia Terminal Based On EPON

Because of the rapid development of Internet services and the coming of various new services, the requirements of network bandwidth are increasing much more rapidly, traditional access network becomes the bottleneck of the whole transmission network. EPON (Ethernet Passive Optical Network) is a leading technology based upon Ethernet and PON to implement broadband applications and multi-services in the future. It has a point-to-multipoint architecture and provides multi-services based on Ethernet. It combines the advantages of PON and Ethernet technology. With its features of high bandwidth, low cost and could be used and updated easily, EPON becomes the best solution for the next generation access network.With the developing of Internet and the wide use of notebook PC and handset, people are eager to contact Internet at anytime and anyplace. The demand of market and the establishment of IEEE802.11 standards lead the local area network to be wireless. WLAN (Wireless Local Area Network) not only has high communication speed, but also has many other advantages. Users can contact Internet at anytime they want and users can move from one place to another within WLAN. WLAN is easy to build, easy to manage and WLAN is cheaper than the wired one.This paper is to research the solution of"last mile"bottleneck with low cost based on the national 863 plan program. With the fusion of OFDM wireless access and EPON technology, researching FTTH the wireless access multimedia terminal to implement the seamless connection between the EPON and wireless access multimedia terminal. Making use of all these advantages to achieve the purpose that consumer can use wide band with low price.
