FiWi ? FUTURE GENERATION BR OADBAND ACCESS TECHN OLOGY

As today’s generation is now became the slave of different internet services at every step of their life. Hence, different researches are carried out continuously sin ce past decade to enhance the performance of existing broadband access networks. The networks which are technically advanced to provide internet services are Passive optical networks (PON), Wireless mesh networks (WMN) and F iber Wireless Networks (Fi Wi). A mong all Fiber - Wireless (FiWi) broadband access network is a promising access technology, because it integrat es the technical merits of both PON and WMN networks such as higher bandwidth of PON an lower cost of WMN . Therefore FiWi provides services to user in “Anytime - Anyway fashion” with high capacity and low cost. Various issues are related to FiWi Network viz. ONU Placement, Survivability and Energy saving. ONU placement are related with, “how efficiently ONUs are place in the n etwork to reduce the overall network deployment cost”. Survivability related to “provide services to users even if the failure occurs in network”. “How to save energy in FiWi network” is related to Energy saving issue. In this paper detail discussion of various issues of FiWi network is done .
