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. I’ll also provide some practical calculations and a link to a Python script which will do the work for you. Please
