DOCSIS

Over the past year, a quiet revolution in broadband services has been happening, thanks to investments cable operators are making around the globe: gigabit services are available to tens of millions households for the first time ever. Already, over half of households in North America can buy a 1 Gbps service from their cable operator, […]

The cable industry is always trying to find ways to improve service. When the cable industry made proactive network maintenance (PNM) a part of the DOCSIS® specifications, we showed great commitment to service. CableLabs supports that commitment through its work in specifications, and particularly through its PNM project. This blog entry in our PNM series focuses […]

In November, CableLabs announced the opening of our new Telecom Infra Project (TIP) Community Lab. Today, CableLabs joins TIP in releasing a whitepaper, making public deeper insights into the vRAN fronthaul interface under development in the TIP vRAN Fronthaul project group. With this new interface, the addressable market for virtualized RAN (vRAN) deployment architectures can […]

Last week, Craig Cowden (Charter), John Chapman (Cisco) and I jointly presented a webinar on improving latency for mobile backhaul over DOCSIS. Moderated by CableLabs’ Rob Alderfer, we: Discussed cable’s wireless strategy and business case for mobile backhaul Did a deep dive into the technical details on how our Bandwidth Report (BWR) proposal can reduce the […]

With 5G and small cell densification on the near horizon, mobile networks need economically viable backhaul solutions. Cable operators are well positioned with fixed networks to bridge that gap, and many operate mobile networks themselves. Could we be on the verge of fixed-mobile network convergence? Things seem to be pointing in that direction, but it […]

Full Duplex (FDX) DOCSIS® (now a part of DOCSIS 4.0 technology) is an update to DOCSIS 3.1 specifications that builds on the core Orthogonal Frequency Division Multiplexing (OFDM) technology. This additional set of features significantly increases upstream capacity and allows for the same spectrum to be used as downstream or upstream. The set of MAC […]

The wireless ecosystem is a rapidly moving marketplace, and the next milestone is the large-scale deployment of small cells to augment network capacities and to support 5G deployments. There are three main elements required to deploy small cells: Location Power Backhaul These requirements put cable operators, many of whom are also mobile operators, in an […]

Recently, in a significant step for the cable industry, we announced the successful completion of the Full Duplex DOCSIS® 3.1 specification (now a part of DOCSIS 4.0 technology). Today, we are pleased to announce the release of the DOCSIS® v3.1 Physical Layer Specification, which incorporates the addition of Full Duplex in Annex F per PHYv3.1-N-17.1771-6. […]

“In the United States, more than 90 percent of households are connected to an HFC (hybrid fiber-coaxial) network, and consumers typically have higher download speeds than upload speeds. By enabling Full Duplex DOCSIS (now a part of DOCSIS 4.0 technology), the upstream can flow up to 6 Gbps and downstream traffic can flow at up […]

Just over two years ago, CableLabs announced the release of a new series of specifications known as “Remote PHY” in the blog “CableLabs® New Remote PHY Specifications expand DOCSIS® Network Deployment Options” authored by CableLabs principal architect Karthik Sundaresan. The blog describes what Remote PHY (R-PHY) is, how it forms a key piece of the […]
