DOCSIS 3.1 includes new technologies and its implementation can be complex, so preparing the network and monitoring its performance is critical. Read on for a few tips on making the rollout as smooth as possible.

Channel Bonding Pushes the Speed Limit

DOCSIS 3.1 adds support for bonding 32 QAM carriers plus 2 OFDM carriers on the downstream, and 8 QAM carriers plus 2 OFDM carriers on the upstream. Proper bonding needs to be verified to assure customers receive their expected service level by performing a DOCSIS 3.1 range and registration test. Proper bonding of DOCSIS 3.0 and 3.1 carriers also must be verified.

 

 

OFDM Changes the GameOFDM Changes the Game

Orthogonal frequency domain multiplexing (OFDM) departs from having a single QAM carrier in 6 MHz to using 4k or 8k overlapping subcarriers across 24-192 MHz. OFDM provides more bits/Hz at the same signal-to-noise operating conditions. The added complexity provides additional efficiency and noise immunity to the cable system.
