Implementation of HFR/WLAN network

Integration of wireless and optical networks is a potential solution for increasing capacity and mobility as well as decreasing costs. By using Hybrid Fiber Radio (HFR) network, a method in integrating wireless and optical networks, the capacity of optical networks can be combined with the flexibility and mobility of WLANs. This paper presents a novel approach in deploying HFR/WLAN network. Proposed method is based on using Subcarrier Modulation (SCM) for multiplexing multiple WLAN signals in RF domain and modulation of a single optical carrier for simultaneous transmission of those signals in downstream direction. In upstream direction, a single photo detector and time division multiplexing (TDM) are employed. Usage of passive optical network (PON) as reliable and mature technology is also proposed for bidirectional duplex transport of optical signals between central site and remote antenna sites.
