CableLabs has issued a series of specifications for DOCSIS 3.0. It will enable cable operators to offer significantly higher speeds with downstream data rates of 160 Mbps and upstream data rates of 120 Mbps.
The Data-Over-Cable Service Interface Specifications (DOCSIS) 3.0, are available at CableLabs. DOCSIS 3.0 features “channel bonding”, which enables multiple downstream and upstream channels to be used together at the same time by a single subscriber. [dailywireless.org]
