Optical Transport Network Design for 5G Fixed Wireless Access

The fifth generation (5G) of mobile technology, 5G is anticipated to be a significant leap in the evolution of mobile communication. 5G will be designed to attain 1000 times higher data volumes, 10 times lower latency, and 100 times more connected devices than its predecessor, 4G. Due to 5Gs ability to sustain high bandwidth per unit area, 5G is considered to be a cost-efficient solution to provide fixed wireless access (FWA) to households on a large scale. FWA is seen as an attractive alternative for fixed broadband access in scenarios where last mile access based on wired technologies is not economically viable. While approaches for enhancing user experience in a 5G FWA environment are investigated in the research community, the problem of providing cost-effective high capacity transport for FWA deployments still remains a major challenge. This is particularly challenging due to diverse transport network architectures and requirements imposed by different 5G deployment models. This paper addresses this problem by formulating a generalized joint-optimization framework to simultaneously plan wireless access and optical transport for 5G FWA networks in order to minimize the deployment cost while meeting various network requirements. We demonstrate the applicability of the proposed framework by applying it to a real scenario with a range of deployment options and where different types of optical x-haul solutions are considered. The results provide a cornerstone for deployment strategies that will be imperative for realizing a future-proof and cost-effective broadband access network

Rethinking of Optical Transport Network Design for 5G/6G Mobile Communication

Driven by the increasing use of emerging smart mobile applications, mobile technology is continuously and rapidly advancing towards the next generation communication systems such as 5G and 6G. However, the transport network, which needs to provide low latency and reliable connectivity between hundreds of thousands of cell sites and the network core, has not advanced at the same pace. This article provides insight into how we can solve the fundamental challenges of implementing cost-optimal transport and 5G and beyond mobile networks simultaneously while satisfying the network and user requirements irrespective of the radio access network\u27s architecture

A small cell augmentation to a wireless network leveraging fiber-to-the-node access infrastructure for backhaul and power

We describe an efficient fiber backhaul strategy for a small-cell network, which leverages facilities associated with an existing fiber-to-the node (FTTN) residential access network. Related optimization studies are also described. © 2013 OSA

Design and Planning for Fiber-Based Small Cell Backhauling

© 2018 IEEE. With the next generation of wireless technology migrating towards smaller cell deployment to cope with the ever increasing traffic demand, the issues with regards to backhauling has to be carefully considered. To achieve a smooth upgrade and transition, small cells and backhaul infrastructure have to be planned simultaneously to ensure optimal cost and performance can be achieved. In this paper, we review the frameworks that we developed to simultaneously plan the small cell locations in conjunction with the optical fiber backhaul networks to achieve cost optimal solution while meeting the network coverage and capacity requirements
