DOCSIS 3.1 Gigabit services ready supporting 2x 196 MHz OFDM and 2x 96 MHz OFDMA channels. Channel bonding of up to thirty-two downstream and eight upstream channels in DOCSIS 3.0 mode.
This paper looks at the two main technologies behind this latest version: orthogonal frequency domain multiplexing (OFDM) and low density parity check (LDPC). It also covers the best testing practices to get DOCSIS 3.1 running at peak performance levels.
The DOCSIS 3.1 standard was created to address two primary needs for cable network operators: higher data throughput to meet consumer demand for high data rate applications and the flexibility to support a variety of applications. DOCSIS 3.1 must be backward compatible with previous DOCSIS generations and also work with TV
