“…Ethernet/Gigabit passive optical network (EPON/GPON) can be used to construct the optical backhaul due its passive distribution and low operational cost. For the wireless last mile, different candidates have already been considered; e.g., wireless mesh networks (WMN) in [1], [4], WMN and wireless fidelity (WiFi) in [2], worldwide interoperability for microwave access (WiMAX) in [3] and long term evolution (LTE) in [5]- [7]. However, the competing technologies for the broadband mobile access networks are WiMAX and LTE.…”

“…However, the competing technologies for the broadband mobile access networks are WiMAX and LTE. In this paper, we consider LTE as it is backward compatible with the existing cellular technologies [7] and can support a data rate upto 100 Mb/s [8]. Manuscript The EPONs consist of an optical line terminal (OLT) housed at a central office, a passive splitter (PS) and optical network units (ONUs) located in the user premises (see Fig.…”

“…Backhauling the LTE network with EPON provides a scope for implementing the X2 interface over the fiber backhaul. Thus, we can get rid of the microwave links by implementing the X2 interface over the fiber backhaul [5]- [7]. This further reduces the CAPEX and OPEX of the network.…”

This paper proposes a ring-based integrated wireless optical network architecture and an associated protocol that involves Ethernet passive optical network (EPON) and long term evolution (LTE) wireless network. The architecture along with the proposed protocol is instrumental toward the reduction of handover delay. The proposed ring-based EPON architecture facilitates the implementation of the X2 interface for LTE network by enabling the optical network units of the EPON backhaul to directly communicate with each other. The work further discusses about an open access network architecture where a single EPON can be used by multiple mobile service providers without compromising information security. Extensive simulations have been carried out to evaluate the performance of the proposed network. An analytical model has been introduced to calculate the queuing delay experienced by the X2 interface. The model has been validated with the simulations results. Index Terms-EPON, handover, LTE, mobile backhauling, open access, ring topology, RPR, token ring, wireless optical integrated network, X2.

The phenomenal growth of mobile backhaul capacity required to support the emerging mobile traffic including cellular Long-Term Evolution (LTE), and LTE-Advanced (LTE-A) requires rapid migration from today's legacy circuit switched T1/E1 wireline and microwave backhaul technologies to a new fiber-supported, all-packet-based mobile backhaul infrastructure. Mobile backhaul, sometimes referred to as the Radio Access Network (RAN), is utilized to backhaul traffic from individual base stations (BSs) to the Radio Network Controller (RNC), which then connects to the mobile operator's core network or gateway. Many carriers around the world are considering the potential of utilizing the fiber-based Passive Optical Network (PON) access infrastructure as an all-packet-based converged fixed-mobile optical access networking transport architecture to backhaul both mobile and typical wireline traffic. This chapter details the case for backhauling wireless traffic utilizing an optical access network, the various standards and technology options for passive optical networks (PONs), as well as the design of a novel, fully distributed, ring-based WDM-PON architecture that could be utilized for the support of a converged next generation mobile infrastructure.
