Centralized processing is expected to bring about substantial benefits for wireless networks both on the technical side and economic side. While this concept considered an important part of future radio access network architectures, it more recognized that current approach fronthauling by employing Common Public Radio Interface protocol will be inefficient large-scale deployments in many respects, particularly new generation 5G.

Given the requirements for a next-generation PON, architecture of system solution must be considered. There are many different systems that can provide services and system-level features desired next generation PON; however, each has its own challenges advantages.

Transport of mobile fronthaul traffic has a tight latency requirement about 250us one-way. The best solutions today are based on expensive point-to-point (PtP) fiber links and PtP wavelength division multiplexing. A time multiplexed passive optical network (TDM-PON) is less expensive, but poor 1ms. Guidelines suggested to design an optimized TDM-PON with minimal for transport constant bit rate traffic. total mathematically analyzed using queuing theory, closed-form formulas derived which...
As 5G networks gain momentum towards commercial deployments, TDM-PON can provide an efficient, cost-effective transport to carry radio signals between processing entities of the Radio Access Network (RAN). However, specifically for fronthaul segment RAN, low-latency requirements are challenging support with existing operation. In this paper, we present analysis latency and some techniques traffic bandwidth efficiency.

Fibre-to-the-premises (FTTP) has been long sought as the ultimate solution to satisfy demand for broadband access in foreseeable future, and offer distance-independent data rate within network reach. However, currently deployed FTTP networks have most cases only replaced transmission medium, without improving overall architecture, resulting deployments that are cost efficient densely populated areas (effectively increasing digital divide). In addition, large potential increase capacity...
