Utilizing OFDM for Measuring Spectrum Performance Above 1 GHz (2023)
By Matthew Olfert, Rogers Communications; Justin Stiles, Charter Communications; Robert Wittmeier, Rogers Communications
Our industry is going through a development phase of our hybrid fiber/coax (HFC) networks. This next phase will rely on orthogonal frequency division multiplexing (OFDM) and orthogonal frequency division multiple access (OFDMA) channels. With new spectrum being utilized for the first time, we can introduce a new activation process to maximize the quality of the spectrum prior to customer utilization. This paper covers the life cycle of plant development that can avoid risks. This new life cycle will utilize multiple data sources to identify potential impacts and provide a key performance indicator (KPI) that can monitor spectrum after service enablement.
