Understanding DOCSIS 4.0

Since its inception over 30 years ago, DOCSIS has made various improvements as a standard that allows the addition of high bandwidth on an existing HFC (Hybrid Fiber-Coaxial) cable technology. The original developer is CableLabs in collaboration with other companies, which include Time Warner, Netgear, Motorola, and Intel Technologies.

Many internet consumers use an HFC network, and DOCSIS technology supports internet providers and users with an increase in their download and upload speeds. The installation of DOCSIS 4.0 on an existing HFC and other hardware is a better option that has no additional costs. It also maintains its compatibility with the previous releases of DOCSIS technology.

DOCSIS 4.0 Developments

DOCSIS technology works with both hardware, and software which enable internet connectivity. They feature the MAC (Media Access Control) layer and the PHY (Physical) Layer. The Mac layer at any time is designed to handle the massive information that is processed.

The PHY layer is a combination of the frequency of data transmission, routing equipment (modem), and the wiring. Here, there are various considerations that affect the performance and speed of transmissions. For instance, the distance between the user’s modem and the infrastructure of the provider can affect the resulting speed of the downstream and upstream.

The emergence of full-duplex DOCSIS technology is a breakthrough in increasing the speeds of downstream and upstream traffic in the networks. Full duplex uses the same spectrum, which collectively doubles the efficiency and convenience of the upstream and downstream functions.

Over the years, the releases from DOCSIS 1.0, DOCSIS 1.1, DOCSIS 2.0, DOCSIS 3.0 to the current DOCSIS 3.1. The future DOCSIS 4.0 will have developments in the maximum download and upload speeds. DOCSIS 1.0 had a 40 Mbps download and 10 Mbps upload, while the previous DOCSIS 3.1 reached maximum download of 10 Gbps and 1 Gbps download. These speeds have enabled internet users to enjoy high internet speeds even during peak periods when there is congestion in traffic.

Software Developers and Small and Medium Businesses

With evolving technologies, software companies are developing new applications that need high resolution and data, and DOCSIS 4.0 can support these developments. These emerging technologies include Augmented Reality and Virtual reality that have a better user experience.

The small and medium businesses are among the biggest gainers with the development of DOCSIS 4.0 technology. Their growth in business relies on targeting a broader audience, and that will need a reliable network with large bandwidth. This technology can be used by many devices concurrently and has higher speeds where their customers can get access to a business’s website from any location. With the use of existing infrastructure, the business will not need to spend money on communication to achieve their business goals.

The Future

With the development of DOCSIS 4.0, the Multi-System Operators can now deliver on the vision of 10G, because of the technology’s full-duplex capabilities. The 10G vision is possible when there is a faster and efficient network, which will support new technology innovations. These will include the inclusion of 10G in the wireless and mobile networks, which will improve the future generation experience.

Also, with more gigabits and fiber connections, this technology will lead the small and medium businesses towards bigger goals and initiatives. With channel bonding, which is the combination of several upstream and downstream channels, users and network providers can increase internet speeds across their range of operations. They will have an advantage of better cloud usage, VoIP phone usage, faster data backup process, video conferencing, and 4K and HD streaming. The technology offers them the convenience of upgrading and customizing their data usage depending on the business needs
