As we enter the new year, consumers, workplaces, and schools continue to rely on video conference applications. We previously studied Bandwidth Usage of Popular Video Conferencing Applications in November 2020 and February 2021.  In May 2021, we studied Hourly Data Consumption of Popular Video Conferencing Applications. Today, we share a study of bandwidth usage on […]

Building on our prior work, this investigation explores the hourly data consumption of popular video conferencing applications: Google Meet, GoToMeeting, Microsoft Teams and Zoom. As video conference applications have become an integral part of our daily lives, we wanted to not only better understand the bandwidth usage as previously explored, but also the total data […]

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 […]

In 1997, CableLabs released the very first version of Data Over Cable Service Interface Specification (DOCSIS ® technology) that enabled broadband internet service over Hybrid Fiber-Coaxial (HFC) networks.  Ever since, we’ve been making improvements, greatly enhancing network speed, capacity, latency, reliability and security with every new version. Today, cable operators use DOCSIS 3.1 technologies to […]

In the middle of a global pandemic, in which people are working and playing on their various devices at home, internet usage is surging—whether because of virtual meetings or streaming entertainment or mindlessly scrolling through apps. And it’s not just the heavily used downstream aspect that’s seeing increased usage, we’re also seeing an increase in […]

You can find the background information for this article in the post “Sharing Bandwidth: Cyclic Prefix Elimination.”  Most wireless transmissions use a modulation technology called OFDM (orthogonal frequency-division multiplexing). This method was invented by Saltzburg and Chen at Bell Labs in the 1960s, but was not widely commercialized until the 1990s when faster signal processing […]

For decades, CableLabs and our member cable operators have been at the forefront of the broadband revolution: connecting hundreds of millions of businesses and households to the Internet, connecting the many internet devices in the home, connecting families and the world to each other. CableLabs has taken the next step to connect two of the […]

“5G” is the next step for the evolution of wireless technology beyond “4G-LTE” with the 2018 and 2020 Olympics acting as powerful Incentives for vendors to accelerate their product development. A few weeks ago, I travelled to San Francisco to chair a session at the new IEEE SDN-NFV conference and to participate in a panel […]

The original title for this blog was supposed to be “DOCSIS® 3.1 Update: Get your engines running,” but in reality, the engines ARE already running!  In fact, the DOCSIS 3.1 engines have been running hot since the start of the year. With the technology rapidly maturing, vendors have accelerated their product development. Let’s take a […]

Service providers and municipalities alike continue their push toward offering gigabit services over fiber networks. In fact, fiberville is a web site dedicated to listing which service providers and municipalities provide fiber solutions. Recently, Comcast significantly upped the ante by announcing a 2 Gbps symmetric service that will become available in certain locations. The services […]
