OFDM Capacity in DOCSIS 3.1 and 4.0

2024-02-28T12:54:24-05:00February 26th, 2024|

Estimating OFDM Capacity in DOCSIS 3.1 / 4.0 A Simplified Approach I am often asked how one estimates the data capacity on a OFDM (orthogonal frequency division multiplexing) channel in DOCSIS 3.1 networks. The question is easy, the answer is not. In this article I provide the background behind estimating OFDM data channel capacity, at least what I can do within the confines of a three-page article. Iโ€™ll also provide some practical calculations and a link to a Python script which will do the work for you. Please

The Reactive Power of DOCSIS PNM Tools

2024-01-16T11:28:31-05:00December 5th, 2023|

In the demanding realm of DOCSIS networks, being proactive has become a necessity, not a luxury. To ensure efficient operation of these networks, cable operators must embrace proactive network maintenance (PNM) tools. These resources not only offer the ability to anticipate and address network issues before they significantly affect service delivery, thus creating a more robust and reliable network for users, but they can also be utilized reactively to help optimize the workforce, improve subscriber quality of experience (QoE) and are not impacted by supply chain constraints. Letโ€™s
