DOCSIS

The Merriam-Webster online dictionary defines de facto and de jure as follows: de facto | di-ˈfak-(ˌ)tō – actual, exercising power as if legally constituted de jure | (ˌ)dē-ˈju̇r-ē – by right, based on laws or actions of the state In law and government, de facto describes practices that exist in reality, even though they are not officially […]

When it comes to technology innovation, one of the most powerful tools in an engineer’s toolbox is the ability to rapidly test hypotheses through simulations. Simulation frameworks are used in nearly all engineering disciplines as a way to understand complex system behaviors that would be difficult to predict analytically. Simulations also allow the researcher to control variables, explore a wide range […]

Today we are pleased to announce the release of the DOCSIS 4.0 specification, which incorporates both full duplex and extended spectrum capabilities. A part of the suite of technologies that support the 10G platform, DOCSIS 4.0 technology achieves a downstream speed of up to 10 Gbps (doubling the maximum download speed available with the implemented DOCSIS 3.1 technology) […]

In a continuing effort to meet the industry’s recently announced 10G goal, CableLabs is wrapping up the first major update to its DOCSIS specification since DOCSIS 3.1. DOCSIS 4.0 technology will enable the next generation of broadband over cable’s existing hybrid fiber coax (HFC) networks, delivering symmetrical multi-gigabit speeds while supporting high reliability, high security […]

Remember the last time you waited (and waited) for a page to load?  Or when you “died” on a virtual battlefield because your connection couldn’t catch up with your heroic ambitions? Many internet users chalk those moments up to insufficient bandwidth, not realizing that latency is to blame. Bandwidth and latency are two very different […]

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 […]
