What are DOCSIS standards?
Data Over Cable Service Interface Specifications (abbreviated as DOCSIS) is a globally-recognized telecommunications standard that enables high-bandwidth data transfer via existing coaxial cable systems that were originally used in the transmission of cable television program signals (CATVS).
What is current DOCSIS standard?
The latest DOCSIS standard, DOCSIS 3.1 is capable of 10 gigabits per second (Gbps) download speeds and 1 Gbps upload speeds. However, the most widespread DOCSIS standard is DOCSIS 3.0, which is capable of 32 download channels at one time and over 1GB download speeds.
What does DOCSIS 3.0 mean?
Data Over Cable Services Interface Specification
DOCSIS 3.0 is the next generation of DOCSIS (Data Over Cable Services Interface Specification), an international telecommunications standard that lets cable television operators add high-speed and telephony data to their current cable TV systems.
What frequency does DOCSIS 3.0 use?
DOCSIS 3.0 used frequency band 5 MHz to 65 MHz for upstream and 85 MHz to 1002MHz for downstream, whereas DOCSIS 3.1 allocates 5 MHz to 204 MHz for upstream and 252 MHz to 1788MHz for downstream traffic.
