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

DOCSIS 3.1 In Your Plant Now In last month's article we focused on demystifying OFDM in DOCSIS 3.1. If you did not read the article please do, because we are going to now build on what we learned last time in the Broadband Library DOCSIS Online article titled “OFDM, completely new in DOCSIS 3.1”. You can find it in the archives with this link: bit.ly/OFDM3 - Also, for those not familair with bit.ly, its just a URL shortening service. Just click on the link or type it into
