Abstract
This paper reviews and outlines the key features of the emerging
next-generation fixed passive optical network (NG-PON)-based and
fourth-generation (4G) mobile broadband access technologies and how to
leverage the advantages of both of these access technologies to build a
next-generation hybrid fiber-wireless (FiWi) network. Specifically, this
paper presents an overview of the most recent research activities on these
hybrid FiWi architectures, aiming to clarify the basic differences and
distinguish between two FiWi networking architectural models, namely, the
overlay or independent model and the truly integrated model. We then explore
and present a new direction to the design and implementation of a simple and
cost-effective all-packet-based converged fixed-mobile access networking
solution that enables the true integration of NG-PON and 4G mobile broadband
access technologies into the envisioned fixed-mobile platform. We briefly
outline the general and technical requirements to support a unified NG-PON
long-term evolution ((LTE) radio access network (RAN) architecture that
conforms to both the typically centralized fixed PON and the emerging
distributed 4G mobile LTE access standards. The implementation methodology
on how to efficiently and cost-effectively integrate these two access
technologies along with the main advantages gained from such an integrated
architecture are outlined and presented.
