connections to the internet and a group of wireless routers. PON in FiWi network can provide up to 1.25 gbps EPON (Ethernet PON) and GPON (Gibit PON) supporting 2.498 gbps in the downstream and 1.244 gbps in the upstream which are very high facilities but wireless communication network still experiences effects of interferences which causes excessive reduction in the network throughput in wireless sub network or Fi-Wi network which becomes a main point IEEE 802.11 standard for WMNS [3] when P2P (Peer to Peer) communication used in Fi-Wi. The network can be increased by increasing traffic for each P2P communication provide more demand of network to increase overall throughput. But it can be delayed in P2P to reduce in the PON network will be faster than in the multi hop wireless network part. These issues will be discussed later in this paper.

In RoF Wi-Fi networks radio frequencies carried over optical fiber links to central office and multiple antenna. RoF network is useful to provide transparency against modulation techniques and also useful to support various digital formats and wireless standards in a low cost manner. The network use optical fiber as an analogue transmission medium between central control office and one or more RAYS. The CO is manager of controlling access to both optical and wireless media. But use of optical distribution system in wireless network may be a negative impact on the performance of medium access control (MAC). The extra propagation delay can exceed certain time out of wireless. MAC protocol and network performance can become very bad. The fig. show the sample ROF Wi-Fi architecture may be used a Fi-Wi network.

technology for network. It often mixed up with (Wi-Fi) but it can be included in (Fi-Wi). Actually Wi-Fi and FiWi pronounced similar sound so many students and academics and other practitioners are not able to differentiate between both. In this paper we analyze to overcome the various problems of implementing (FiWi) in practical and we provide the researchers to find future direction and to general readers to understand
Introduction
The use of (Fi-Wi) or optical wireless is combined use of optical fiber and wireless (radio frequency) for communication to provide telecommunication services in bulk for distant or remote areas. This combination (PONS) Passive Optical Network and (WMS) Wireless Mess Networks is designed to provide network in very far and remote areas. The high capacity optical fiber used to provide cheap wireless link to carry the signal to the last user. The Fi-Wi can be used various types of communication such as upstream, downstream, peer to peer communication. Fi-Wi network consists of a wireless-sub network as the front and back end.
