bandwidth

As consumers’ bandwidth needs continue to grow, cable operators are always thinking of ways to expand their network capacity to accommodate future increases in data traffic—especially upstream traffic. Band splits play an important role in that effort, taking advantage of the incredible resiliency of cable’s hybrid fiber-coaxial (HFC) network. What Is a Band Split and […]

As working from home and remote schooling remain the norm for most of us, we wanted to build on and extend our prior investigation of the bandwidth usage of popular video conferencing applications. In this post, we examine the use of video conferencing applications over a broadband service of 50 Mbps downstream and 5 Mbps […]

This year we have seen a shift toward working and learning from home and relying more on our broadband connection. Specifically, most of us use video conferencing for work, school and everyday communications. With that in mind, we looked at how much video conferencing a broadband connection can support. In the U.S., the Federal Communications […]

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 […]

In the era of cloud computing—a predecessor of edge computing—we’re immersed with social networking sites, online content and other online services giving us access to data from anywhere at any time. However, next-generation applications focused on machine-to-machine interaction with concepts like internet of things (IoT), machine learning and artificial intelligence (AI) will transition the focus […]

Unfortunately, there is only so much over-the-air wireless bandwidth, and it must be shared between a lot of folks. And the situation is not getting any better.  While you can usually run another wire or fiber optic cable between two locations to get more bandwidth, if you have a wireless application you must share this […]

At CableLabs, we are continually researching new methods of in-home wireless network distribution, and one exciting new contender is Li-Fi. What is Li-Fi? Li-Fi is the modulation of a free-space beam of light in order to transmit a signal. It can be thought of as analogous to Wi-Fi, just in a much higher frequency band […]
