Part of operationally-hardening DOCSIS 3.1 involves determining effective modulation profiles, which Comcast and other service providers are doing with a profile management application (PMA). Hear from Comcast about the opportunities and challenges associated with the wider OFDM channels of DOCSIS 3.1 and how they impact network stability and performance. Also, CableLabs will present on how a well-designed, optimized set of modulation profiles allows a channel to operate more robustly against ingress noise and also enables an overall higher user throughput.
