Time is Ripe for D3.0 Farming: Achieving Optimal Spectral Efficiency by Allocating D3.0 Spectrum to OFDM (2022)

By Maher Harb, Chad Humble, Sebnem Ozer, Dan Rice; Comcast

This paper introduces a fresh perspective on optimizing the spectrum to achieve desired outcomes for product speeds, capacity, node segmentation, and cost effectiveness. The goal of the optimization exercise is to maximize spectral efficiency via reallocation of DS D3.0 channels to OFDM while accounting for any increase in utilization, which may lead to costly node augments. We show that the current configuration and CMTS load balancing place a higher burden on the OFDM spectrum, thus making the conditions ripe for spectral reallocation. This reallocation creates a material positive benefit in support of multi-Gbps products. Lastly, we present a VNF concept to farm the D3.0 spectrum and manage load balancing in an automated fashion.
