Wireless access can support flexible and ubiquitous communication in small community areas with a low deployment cost However, interference and low bandwidth limit wireless network’s deployment scalability A FiWi access network consists of a wireless sub network as the front end and an optical sub network as the back endĤ Introduction The FiWi must be able to efficiently support upstream, downstream, and peer-to-peer communications The integration of PONs and WMNs in FiWi access networks provides an opportunity to reduce the impact of interference on the network throughput The FiWi can potentially reduce the delay for some p2p communications since the transmission in the PON network can be much faster than that in the multi-hop wireless network.ĥ Agenda Related work and preliminary knowledge 1 FiWi Integrated Fiber-Wireless Access NetworksĢ Introduction FiWi access networks introduce wireless-optical-wireless communication FiWi access networks enable traffic to be sent from the source wireless client to an ingress ONU, then to the egress ONU close to the destination wireless client, and finally delivered to the destination wireless client FiWi supports direct inter-ONU communication in the optical sub networkģ Introduction Optical access provides huge bandwidth, but it is costly to achieve deep fiber penetration.
