Integration of OCDMA based NG-PON and Fi-Wi networks for wireless access

Emerging applications such as High Definition TV (HDTV), video-on-demand, high-quality audio transmission telepresence and digital cinema demand high-throughput access networks with stringent Quality of Service (QoS) requirements. Optical access networks can provide huge bandwidth but it cannot reach every end user. On the other hand, wireless access networks can support mobility to reach every end user but its offered bandwidth is limited. By combining the high capacity of optical fiber network and the mobility of wireless network, fiber-wireless network can provide customers with quad-play services (data, video, voice and mobility). Optical Code Division Multiple Access (OCDMA) is one of the promising multiple access methods for Passive Optical Networks (PONs) since it offers various advantages such as simplified network architecture, protocol transparency, enhanced security and asynchronous operation. Long Term Evolution (LTE) is the most recent and enhanced technology which is being adopted around the world as the primary telecommunication service. As per LTE standard, Orthogonal Frequency Division Multiplexing (OFDM) is used for downlink and Single Carrier Frequency Division Multiple Access (SC-FDMA) is used for uplink. This paper proposes an architectural integration of OCDMA based Next Generation PON (NG PON) and wireless LTE technology. Spectral Amplitude Coding (SAC) is used for OCDMA.
