Gigabit internet plans may be costly, but the high speeds make it worthwhile for avid streamers and online gamer. One way to mitigate this cost is by ditching your rented networking equipment and providing your own gigabit modem and router.
What is DOCSIS Cable Modems?
DOCSIS (Data Over Cable Service Interface Specification) is a technology developed by CableLabs for transfer of data over coaxial cable that are deployed and used for cable TV connection. Cable operators across the world have adopted DOCSIS standards in Cable Modems for providing internet data, voice and video services using existing cable TV systems.
What is the key advantage to DOCSIS 3.1 technology in Cable Modems?
One of the key advantages of DOCSIS 3.1 over Fiber is that it uses the same ‘last mile’ technology – the coax cable – to support the higher Gigabit speeds. Fiber requires a completely new infrastructure and new cable layouts to the home, making deployment costs much higher. DOCSIS 3.1 technology in cable modems is a much more cost-effective technology for cable internet providers to implement.
DOCSIS 3.1 offers a huge jump in download and upload internet speeds over DOCSIS 3.0, supporting up to 10 Gbps download and 1 Gbps upload speeds. Using DOCSIS 3.1, Comcast is offering Gigabit and Gigabit Pro Internet service with 1 and 2 Gigabit download speeds.
If your endgame is Gigabit-speed Internet, then you will have to upgrade to a DOCSIS 3.1 modem sooner or later. The main benefit of this technology is that its max downstream caps out at 10Gbps and its upstream caps out at 2 Gbps. Gigabit speeds are offered by the nation’s largest ISPs, including Comcast Xfinity, AT&T, Cox, CenturyLink, and Google Fiber. If you live in a metropolitan area, you are probably in one of these networks.
