When buying your home router have you ever stop to ask what some of the abbreviations mean? One of these is DOCSIS (Data Over Cable Service Interface Specification), which is the technology standard that helps to determine your broadband speed. As cable operators delay the role out of FTTH (Fibre To The Home) and try to get more speed out of copper wire, you will need a gateway router that support these latest standard to take advantage of the speed improvements. This will help to improve your download experience such as when you are streaming Ultra HD television content, playing real-time gaming and remote home monitoring.


The latest DOCSIS standard is version 3.1, this offers a 100x increase in average data speed rate to your home and is 25 percent more efficient than earlier versions of DOCSIS. This means you are getting hundred more megabits of broadband bandwidth to enjoy your internet browsing.

Although your cable Internet bandwidth is shared with other cable subscribers in your neighbourhood, so you may see decreased performance during peak usage times.
