CableLabs Brings Mobile Wi-Fi’s Power to Wi-Fi Industry for a Better User Experience 

CableLabs Mobile Wi-Fi

Wi-Fi can be frustrating! It sometimes works and sometimes doesn’t. Identifying the problems can be difficult, and people often just turn Wi-Fi off on their device and instead use their cellular data connection. In doing so, they miss out on the potentially much higher throughput, and hence the faster Internet connection, that a Wi-Fi connection can provide. If only Wi-Fi acted more like the cellular network!

What Is CableLabs Mobile Wi-Fi?

For several years, CableLabs has been working on a technology to achieve exactly that. CableLabs Mobile Wi-Fi uses a central controller to group multiple access points or APs (think routers) into one continuous network. The central controller detects which AP your device is closest to and connects your device to that AP. If you move—for example, getting up and walking to a different room—then the controller evaluates whether you would get the best experience by staying connected to the old AP or if your experience would be better by switching to a new one. If it’s the latter, the controller moves your device to the new AP without you even noticing.

There have been many attempts to do this over the years, typically relying on coercing the device to reconnect to the new AP, but this frequently seems not to work quite right. Sometimes, there’s a lag before a device switches APs, and sometimes the device never switches APs. Or sometimes, the device insists that an AP is still present, even though it no longer is—for example, when you leave your house in your car and your phone insists it's still connected to your home Wi-Fi.

How Does CableLabs Mobile Wi-Fi Work?

Instead of asking the phone to reconnect to a different AP, CableLabs Mobile Wi-Fi moves the network itself to the new AP. It does this using a virtual Basic Service Set, or VBSS. A VBSS is a network set up exclusively for use by one device and can be moved from AP to AP without the device disconnecting and reconnecting. This makes the transitions between APs seamless and transparent to the phone.

So now, as you walk around your house with your device, the CableLabs Mobile Wi-Fi controller is moving your VBSS such that it follows along with you, hopping from one AP to another as you go. If you wander too far and go outside the range of all your APs (like when you drive away in your car), the CableLabs Mobile Wi-Fi controller detects this, closes your connection and tears down your VBSS so that your phone immediately knows there is no longer a Wi-Fi connection. The phone will then immediately switch to cellular data.

The result is that your device will be consistently connected to the best available AP in your space. Gone will be the days of being connected to an AP across the house instead of the one right next to you. Your Wi-Fi will be better and faster.

When Can I Get It?

CableLabs Mobile Wi-Fi is not yet available to end consumers. For the next step toward a commercial implementation of CableLabs Mobile Wi-Fi, CableLabs has joined and is working with the prpl Foundation to include Mobile Wi-Fi in the open-source prplMesh implementation of Wi-Fi Alliance EasyMesh™️. Go to the prpl website for more information about prplMesh and access to the prplMesh codebase. CableLabs is also working in Wi-Fi Alliance to support Wi-Fi CERTIFIED EasyMesh.

A Ton of Savings—Thanks to Energy-Efficiency Voluntary Agreements

Energy-Efficiency Voluntary Agreements

Debbie Fitzgerald
Technology Policy Director

Oct 18, 2022

What weighs more, a ton of carbon dioxide gas or a ton of bricks? Well, that’s a trick question because they both weigh one ton! It’s difficult to imagine that a gas can be measured in terms of weight, but that’s how carbon dioxide, or CO2, is measured. CO2 is technically measured in terms of metric tons. One metric ton of CO2 would fill a cube roughly 27 feet tall, wide and deep!

In the U.S. Set-Top Box Voluntary Agreement (VA), we use the EPA greenhouse gas equivalencies calculator to quantify how many metric tons of CO2 are avoided, or saved, when we reduce the energy consumed by set-top boxes (STBs). The VA’s independent annual report was recently released, and the savings trends continue! D+R International reported that the voluntary agreement avoided 13 MILLION metric tons (MMT) of CO2 in 2021 alone and nearly 64 million metric tons in the nine years of the agreement!

CO2 Avoided Due to the Set-Top Box Voluntary Agreement

The chart below shows the impressive trend of reduced energy consumption over the nine years. This chart represents the estimated energy use of deployed STBs in the United States among cable, telco and satellite providers.

Annual Energy Used by Set-Top Boxes

I will note that the number of deployed STBs has also declined, from an estimated 227 million in 2012 to 155 million in 2021. This is partly because of subscriber losses but is also attributed to whole-home DVR solutions and solutions to view pay TV content directly on TVs, phones, tablets, etc. (According to the report, an estimated 56 million devices accessed subscriber content through apps.) However, another interesting chart from the report shows that the average weighted typical energy consumption (TEC) of only the newly purchased STBs, as reported every year by the signatories, has also been reduced over the years by 57%. This is an important metric because it shows improvement without factoring in the smaller number of deployed STBs.

Average Weighted TEC of Purchased STBs by Year

Small Network Equipment Energy Efficiency Gains

The 2021 Small Network Equipment Report was just released and also demonstrates continued energy efficiency trends even as the demand for faster and more capable broadband grows.

Weighted Average Energy Usage by Equipment Type, Relative to Average Broadband Download Speed

Canadian Energy Efficiency Voluntary Agreement (CEEVA)

Canada also has voluntary agreements for set-top boxes and small network equipment. CEEVA STB has been in place for five years and has demonstrated a very similar trend as the United States, as shown in the chart below. (Note: PVR stands for “personal video recorder,” which is called a “digital video recorder,” or DVR, in the United States.)

Weighted Average TEC, by Set-Top Box Category 2017-2021

This is only the first year that SNE procurement commitments were in effect in Canada and just the second year to report purchases. Yet the results already show an exciting increase in energy efficiency—an improvement of 34% from 2020 to 2021!

Renewed Level of Commitment

Returning to the discussion of CO2, the cumulative impact of these programs is making a significant difference, and the programs are only gaining momentum. The U.S. SNE voluntary agreement has been renewed and extended through 2025 and has added several new signatories, including Google, Amazon eero, TP-Link and Sagemcom. In addition, California’s Pacific Gas and Electric Company has joined the SNE VA as an energy efficiency advocate. The U.S. STB voluntary agreement renewed its commitments last year to run through 2025, and Canada renewed both CEEVA STB and SNE to run through 2026. CableLabs is proud to help lead the charge to reduce the carbon contribution of STBs and SNE in North America while enabling the industry to continue innovating on the platforms.

10G Challenge Winners Leverage Power of Multi-Gigabit Network

10G Challenge Winners


Oct 6, 2022

What if our loved ones could easily receive life-changing or even lifesaving medical care no matter where they live? What would be different if critical learning opportunities were broadly available to students from all communities, including urban and rural areas? Scenarios like these could certainly change how we live our lives.

In 2021, CableLabs issued a challenge to individuals and organizations to think big. On behalf of the cable industry, we launched the first-ever 10G Challenge, asking innovators to imagine technologies that the emerging 10G network will make possible. We wanted to know how their creations would leverage the four pillars of the multi-gigabit platform: faster internet speeds, better security, lower latency and improved reliability. We heard from innovators across the United States and Canada who are developing valuable solutions to some of today's biggest problems.

At SCTE Cable-Tec Expo 2022, CableLabs recognized the six winners of the 10G Challenge and now we're thrilled to introduce the winners and their innovations here. In the coming weeks, we’ll be sharing more about these prize-winning ideas, as well as insights directly from some of the creators.

Prizes to Accelerate Innovations

In total, CableLabs awarded more than $300,000 in cash prizes to the six winners of the 10G Challenge. The hope, CableLabs' McKinney said during the winners' showcase event, is that the prize money would be used to help build on the innovators' progress and bring their winning ideas to market.

"We're all about asking—and answering—What if?" McKinney said during the event, echoing comments from the opening general session of Cable-Tec Expo where he announced the newest short film in CableLabs’ Near Future series. "What if we could change the health care profile around the world? What if we could change education? What if we could change our ability to live, work, learn and play?"

What Is the 10G Network?

In short, the multi-gigabit platform is the broadband network of the future that will support whatever comes next. The imminent 10G platform will deliver internet speeds up to 10 times faster than what most consumers experience today for both upstream and downstream traffic—plus enhanced reliability and security. What's even more exciting is that the infrastructure to support these high-speed internet capabilities is already in place! And it leverages CableLabs technologies like Proactive Network Maintenance (PNM), DOCSIS 4.0 specifications, P2P Coherent Optics, Low Latency DOCSIS and many others.

L4S Interop Lays Groundwork for 10G “Metaverse”

Low Latency, Low Loss, Scalable Throughput (L4S) technology

Greg White
Distinguished Technologist

Aug 25, 2022

What does the future look like to you? Your vision could very well be dependent on L4S—Low Latency, Low Loss, Scalable Throughput—technology. A key component of the Low Latency DOCSIS® specifications, L4S is fundamental to the cable industry’s 10G initiative and underpins three of the four tenets of the multi-gigabit platform: speed, low latency and reliability. By allowing applications to fully make use of multi-gigabit connections and, in the process, achieve ultra-low latency and near-zero packet loss, L4S will change what's possible in broadband networks.

The technology will enable the interactive and immersive media experiences of the future—“metaverse” types of augmented reality (AR) and virtual reality (VR) applications that once were only a figment of science-fiction imagination. L4S can also make possible applications that haven’t been envisioned yet! And now, we’re a step closer to deploying this critical technology after an interoperability event that drew participants from organizations including Apple, Google, Meta, NetApp, Netflix, Nokia and NVIDIA, as well as cable industry orgs Casa Systems, Charter Communications, Comcast and CommScope.

Low Latency DOCSIS Specs and IETF Standards

CableLabs and Kyrio, with support from Comcast, Apple and Google, organized the Interop event—the first in the world to test implementations of L4S. As an early adopter, promoter and contributor to the development of the technology, CableLabs has positioned the cable broadband industry to take the lead in capitalizing on this transformational change in the way applications interact with the internet. CableLabs integrated support for L4S into its Low Latency DOCSIS specifications from the beginning and has been a leader in pushing for its standardization in the Internet Engineering Task Force (IETF).

L4S Interop Participants at "Hackathon"

Engineers participate in the L4S Interop in July.

Broad Range of Participants

The four-day Interop event, held in coordination with the IETF during the organization’s “Hackathon” in late July in Philadelphia, drew 32 engineers from 15 organizations. The engineers tested and refined their applications on Low Latency DOCSIS gear, including cable modems using Systems-on-a-Chip (SoCs) from multiple suppliers and cable modem termination system (CMTS) equipment from Casa Systems and CommScope. In addition, two L4S-enabled Wi-Fi access points—one from Nokia and the other from Google Nest—participated, and Nokia brought a 5G network emulator.

The goal of the event was to allow engineers to test and refine their implementations, rather than to demonstrate the capabilities of the technology. But we did manage to publish some impressive early benchmark results and demonstrate some of the applications nonetheless. In the first public demonstration of Apple’s QUIC-Prague L4S congestion control design (recently announced at WWDC 2022) running over a Low Latency DOCSIS connection, the implementation achieved up to 50x reduction in latency and jitter and 70x reduction in packet loss. On the application front, NVIDIA demonstrated the L4S-enabled version of its GeForce Now cloud gaming service, and Nokia demonstrated a telepresence application that allows a user to use a touch screen to remotely control the live view generated by a 360° camera.

Continuing the Momentum

This was an important and successful first event for the cable industry and the internet, but we’ve only just begun. CableLabs and Kyrio plan to host a follow-up event at our Louisville, Colorado, headquarters in October, and we plan to facilitate another event in London in November. We welcome CableLabs members, cable vendors, application developers and other L4S implementers to join us at these upcoming events as we continue to advance in our march toward 10G. To register for the October L4S Interop, click the button below.

In addition, Kyrio provides a service for application developers who wish to test their 10G L4S applications using Low Latency DOCSIS network gear—privately, on their own time and at their own pace. If you’re interested in Kyrio’s testing services, learn more or contact the team here.



A Jolt of Light: CableLabs Holds First 200G P2P Coherent Optics Interop

200G P2P Coherent Optics Interop

Matt Schmitt
Principal Architect

Jul 28, 2022

Anyone remember the jingle for Jolt® Cola? All the sugar and twice the caffeine! Perhaps the phrase dates me, but I still hear it in my head—although I now have new words to set to it:

All the distance and twice the capacity!

OK, maybe it doesn’t have quite the same ring to it. But it’s still exciting because that’s what was demonstrated last month in our labs for Point-to-Point Coherent Optics (P2PCO). We confirmed that devices compliant with CableLabs’ P2PCO PHYv2.0 specification can transmit over roughly the same distance as devices compliant with our P2PCO PHYv1.0 spec, and at double the operating capacity: 200 Gbps vs. 100 Gbps per wavelength. Even more importantly, this result was achieved while also demonstrating multi-vendor interoperability, a key component of achieving scale and promoting competition in the marketplace. All together, these developments allow operators to cost-effectively expand the capacity of the fiber that’s already deployed in their access networks.

We validated interoperability and performance at one of CableLabs’ Interop events, as we’ve done in the past for other technologies, including coherent optics. These events provide an opportunity for multiple manufacturers to get together on neutral ground and test how their products work with each other. In fact, we held Interop events for devices compliant with our P2PCO PHYv1.0 specification, which defines operation at 100 Gbps per wavelength, back in December 2018 and June 2019.

So why the long delay between those tests and June’s Interop? While support for 200 Gbps per wavelength does require new digital signal processor (DSP) silicon, we had originally planned to hold our first 200G event in late 2020. And we all know what happened in 2020—and 2021!

Representing the Majority of the Coherent Optics Industry

Fortunately, the manufacturers didn’t waste that additional time. Instead, they used it to further develop their products. As a result, this was possibly one of the most boring Interop events I’ve ever been a part of—because things simply worked! I won’t claim that troubleshooting wasn’t necessary (it virtually always is), but the manufacturers’ ability to quickly get their devices working with each other was truly impressive.

The Interop participants were:

The number of participants might not be high, but what’s important is that the participants include DSP silicon from multiple manufacturers that represent the majority of the coherent optics industry. Demonstrating interoperability among so many different coherent DSPs bodes incredibly well for operators because it allows them to avoid being locked into single-vendor solutions, which promotes scale and competition.

Another Piece of the 10G Puzzle

As operators move toward the deployment of 10G-capable networks, guaranteeing sufficient capacity across the entire network will be critical for ensuring great customer experiences. P2P coherent optics represents a cost-effective means of increasing the capacity of the existing network. This enables the deployment of new, higher-speed connections into customer homes via technologies like DOCSIS 4.0 at lower costs and opens up new service opportunities, such as support for wireless.

When cable operators deploy coherent termination devices (CTDs) in their network, they may choose to initially deploy them using 100G transceivers. Then, when it’s needed, they can simply replace a pair of transceiver modules with this 200G technology to double the capacity of their network links without relocating or adding other equipment. This allows operators to scale their network capacity quickly and easily based on demand, while spending only what’s needed when it’s needed.

We believe that will serve as an incredibly powerful tool in their toolset, putting in place one more piece of the puzzle that will ultimately power a 10G future.

  10G Advances: DOCSIS 4.0 Technology Demonstrates Unmatched Speeds



Jun 28, 2022

In today’s world of hyper-connectivity, we depend on network performance more than ever before. Whether we’re logging on for a workday full of videoconferencing, settling in for an evening of digital entertainment or simply taking advantage of the smart devices in our homes, our need for efficient, immersive digital experiences grows every day. The 10G platform promises high speeds, low latency, increased security and enhanced reliability—all necessary in addressing the demands of our digital future.

For most consumers, 10G means internet speeds that are 10 times faster than what they currently experience. But the best part is that the infrastructure to power 10-gigabit speeds is already in place. Thanks to DOCSIS 4.0 technology, the potential of this existing infrastructure can be fully tapped to deliver never-before-seen speed.

DOCSIS 4.0 Technology

Multi-gigabit speed took center stage in CableLabs’ recent 10G Showcase. During the showcase, cable operators Charter Communications and Comcast presented DOCSIS 4.0 prototypes capable of nearing that 10-gigabit target, giving attendees a first look at history in the making and proving that real-world deployment of 10G isn’t far off.

In their demos, the companies highlighted multi-gigabit symmetric capability using Remote-PHY and Remote-MACPHY devices built to CableLabs’ specifications. First, Charter’s John Williams and Matt Peterson demonstrated multi-gigabit symmetric capability using the DOCSIS 4.0 extended spectrum mode of operation. In the demonstration, Charter used spools of cable to simulate real-world deployments. Then, Rob Howald of Comcast displayed the same symmetric capability using the full duplex mode of operation in four separate demos, two of which were managed by a production virtual cable modem termination system (CMTS) located in a Comcast office about 40 miles away, thereby demonstrating the power of virtualization and disaggregation.

For more details about the demonstrations from Charter and Comcast, including how they were configured, watch the video below.

10G Challenge


Jun 7, 2022

We want to hear from forward-thinking entrepreneurs, accelerators and makers whose big idea will revolutionize the way we live, work, learn or play—the four categories of the 10G Challenge. This could include anyone from large companies and startups to university students, professors and classes to anyone who is working on the next big thing in their garage. We’re all ears!

CableLabs members aren’t eligible to participate, but we want them to encourage any potential contestants they know to submit their ideas.

How to Enter

Entering the 10G Challenge is easy. Innovators simply fill out the application and share a 3-minute video describing or demonstrating the technology, service or application that they’re developing or plan to develop. In the video, applicants should share their vision, including:

  • the problem their technology solves;
  • a description or demonstration of their solution;
  • why their technology is dependent on the reliability, securityspeed and/or low latency that 10G promises; and
  • how their solution impacts the way we live, work, learn or play.

Even if an idea is still in the concept stage, it will be considered as long as every question on the submission form is answered and a video describing the technology is included. The deadline to submit is July 1, 2022.

Cash Prizes

Six winners will be chosen: One winner for each category, a Grand Prize Winner and a People’s Choice Winner. Each category winner will receive a cash prize of $50,000, with the People’s Choice Winner receiving $10,000 and the Grand Prize Winner taking home $100,000. In addition, the Grand Prize Winner and four category winners will have the opportunity to present their technology to industry leaders at SCTE Cable-Tec Expo, taking place September 19–22, 2022, in Philadelphia.
