OFDM and OFDMA The value added and what it means to my network By now you have heard or have been exposed to orthogonal frequency division multiplexing (OFDM). It was the innovative technology introduced in Data-Over-Cable Service Interface Specifications (DOCSIS) 3.1 to increase the efficiency by which DOCSIS networks can transmit data in the downstream. Additionally, many cable operators are now actively deploying orthogonal frequency division multiple access (OFDMA), which was also introduced in the DOCSIS 3.1 specification in order to increase upstream bandwidth efficiency. So just what
