Cryptography is a foundational security technology used to protect digital information by providing the underpinnings for confidentiality, authentication and integrity. Today’s cryptographic algorithms may soon be undermined by emerging attacks, including the realization of a cryptographically relevant quantum computer (CRQC). Such attacks pose a very real and increasingly urgent threat across virtually all industries and their technologies, including broadband network infrastructure.

With cryptography and public key infrastructure being foundational to the security of cable networks, the broadband industry is uniquely positioned to rise to this challenge and seize the opportunity to future-proof networks to be robust, flexible and responsive to any cryptographic threat — quantum or otherwise. In this blog, we’ll review the threats against cryptography on the horizon, the solution to mitigate those threats and actions to start migration to new cryptographic paradigms. Many organizations, including network operators, have started taking action to plan for and execute cryptographic migrations.

The Threat: Attacks Against Cryptography

So, what exactly is the risk? To put it simply, quantum computers will one day be powerful enough to crack the asymmetric cryptography that is the basis of confidentiality, authenticity and integrity of data at all layers for virtually all devices deployed today. The current timeline for the potential development of a CRQC is 10–30 years — with increasing probability. That estimate isn’t certain, and recent research advancements suggest that it could be sooner.

While that time frame is wide, the risk of compromise is relevant today, thanks to the “harvest now, decrypt later” style of attack. In this scenario, adversaries may capture encrypted data today and retain it, planning to decrypt it once they have access to a CRQC. Any sensitive data generated today that will remain sensitive in the future (such as health records) is therefore at risk today.

The Solution: Cryptographic Agility and Post-Quantum Cryptography

So, how can the industry future-proof itself against these threats? The solution is twofold:

• Enabling cryptographic agility: Cryptographic agility is the ability to switch cryptographic systems quickly and efficiently. It’s a forward-looking design principle and capability that helps security interfaces stay flexible and adaptable in the face of all future threats.
• Post-quantum cryptography (PQC): Also called quantum-safe cryptography, these new encryption algorithms are designed to resist attacks from quantum computers. Their standardization, primarily driven by the National Institute of Standards and Technology in the United States, is a global effort that’s been ongoing for the last decade.

PQC aims to be the replacement for today’s vulnerable cryptography. Cryptographic agility is the framework by which systems will be migrated to PQC (and future iterations of cryptographic algorithms). Together, these strategies offer a path forward.

Migrating to PQC and Leveraging Existing Guidance

From existing guidance on cryptographic migrations, the CableLabs Future of Cryptography Working Group — a collaborative initiative bringing together operators, vendors and security experts to prepare for and to navigate changes to evolving cryptography — has identified certain “no-regret” actions, which can benefit network security posture regardless of whether or when the threat of a CRQC is realized. Some of these no-regret actions include:

• Establishing a cryptographic inventory: A comprehensive inventory of what cryptography is deployed is a critical artifact for any organization to compile as a first step towards cryptographic migrations.
• Assessing and estimating cryptographic agility enablement: Cryptographic agility is a deceptively simple concept; effectively enabling it begins with quantifying how cryptographically agile security interfaces are today. Tools exist today to aid in that effort.
• Discussions with vendors: Vendors play a critical role in cryptographic migrations, providing the implementation of security interfaces and concretely enabling cryptographic agility. Therefore, early and ongoing engagement with vendors on their roadmaps for enabling cryptographic agility and migrations to new cryptographic paradigms is key.
• Risk assessments and defining risk tolerance: Migration of cryptography at full organization scale is an optimization problem; undertaking risk assessment activities to identify the devices, services and interfaces that are at highest risk and should be prioritized for migration is crucial.

Taking Action Through Collaboration

Over the next decade, regulatory bodies around the world expect critical infrastructure — including broadband networks — to adopt quantum-safe cryptography. That makes the next five years crucial for operators looking to future-proof their networks and enable cryptographic agility as a key security capability. Reaching that goal will require deep collaboration, not just between network operators, but across the entire ecosystem of equipment manufacturers, software developers and standards organizations.

To ensure a smoother transition, the CableLabs Future of Cryptography Working Group is continuing to drive the foundational work to adapt current crypto migration and agility guidance to cable networks, identifying gaps therein and developing strategies to address those gaps. The working group’s mission is to develop practical, industry-specific guidance for enabling cryptographic agility as a new capability and migrating operator networks to post-quantum cryptography.

The threat may be complex, but the goal for the cable broadband industry is simple: Keep our networks — and the people who rely on them — secure for the future. To learn more or if you’re interested in contributing, the Future of Cryptography Working Group is open to CableLabs members and our vendor community. Join us here.

Ransomware has changed a lot in the past few years. The term refers to a form of malicious software loaded by attackers to restrict access to files and other data with the intention of extracting payment from the owners of that data.

CableLabs has been working to make sure that residential and business subscribers have the tools they need not only for preparedness and prevention, but also in the event that ransomware actors target them.

Let’s take a look at how the ransomware landscape has evolved, how law enforcement has changed its approach and how one important document can alter the course of your network’s future.

The Law Enforcement Front

The global climate on the regulatory, legislative and law enforcement front has changed, as you can see in the table below.

Evolving Threat Actor Behavior

We’re also seeing changes in threat actor behavior. There’s been a sharp increase in both the number of victims (over 200 percent) and the number of ransomware variants (over 30 percent) in 2025 — a deviation from last year’s trends.

The increased use of ransomware-as-a-service (RaaS), the open availability of threat tools and malicious actor communication all continue to evolve. No longer does the threat actor have to find a way to access systems, they can now buy opened systems and immediately move to the ransom phase. The horizontal disaggregation of the marketplace has enabled more threat actors to engage against more victims, with less technical know-how. Exploited vulnerabilities are now the primary method of malicious access, followed by compromised credentials and email/phishing.

Collaborating to Combat Threat Actors

CableLabs engages with several Information Sharing and Analysis Centers (ISACs) and anti-abuse groups. One of the more focused groups is the Messaging, Malware and Mobile Anti-Abuse Working Group (M³AAWG), where we’re proud to have helped to both originally build (and then shepherd updates to) the “M³AAWG Ransomware Active Attack Response Best Common Practices” document.

We do this work because — although the dogma of cybersecurity defense is to prepare, prepare, prepare — the reality is that no matter how good a network’s defenses are, they can always be stronger.

The Best Common Practices document starts with advice from victims who were previously infected, moves on to steps to follow, lists numerous resources, provides a high-level view of what to expect and finally offers decision guideposts about who to involve and when. The document helps with detection, analysis and response activities; demonstrates how to communicate; and enumerates the deliverables necessary for each stage.

This document doesn’t prescribe specific behaviors, but it helps to make sure the reader is equipped with the right questions to ask, as well as the considered order of approach to tackling a problem.

There will be decisions to make about when to declare an event, whether you have reporting requirement, what law enforcement’s role will be, which disclosures are necessary, whether you pay a ransom (or whether that is legally permissible in your situation), when and how to engage on cybersecurity insurance, and what your potential negotiation options are.

There are always collateral victims in attacks like these, and there may be actions possible or preferable on those fronts that will need to be evaluated. That process is one of many that will involve others within the organization. This document helps lay out who should be considered in each step.

The Importance of Having a Plan

Everyone hopes that this aspect of the global economy will come to a decisive end but, in reality, that’s neither the trend nor the expectation. In a dangerous world, it’s best to have a plan for how your company will act in a multitude of situations — even the unpleasant ones.

The Best Common Practices document is a tool for checking existing policies, technologies and the people involved in the prevention plans, but it can also be a cheat sheet for those who have had to balance other needs against external threats and suddenly find themselves in a difficult situation.

Read the “M³AAWG Ransomware Active Attack Response Best Common Practices” document to learn more about the options that are available for victims of ransomware attacks. The document is one resource in a broader cross-sector toolkit that helps defend against and manage the risk of ransomware threats. For more, check out:

Winston Churchill famously said, “If you’re going through hell, keep going.”

These resources can show you how.

When people think about fighting climate change, they may picture solar panels on rooftops or wind turbines on hillsides. What’s less obvious is the quiet revolution happening inside our homes — through the very devices that connect us to TV and the internet.

Three new reports from the United States and Canada tell a clear story: The everyday set-top boxes and network gear we rely on are getting considerably more efficient, cutting energy usage while keeping pace with our growing digital appetites.

Efficiency Alongside Innovation

The 2024 U.S. Small Network Equipment (SNE) Report shows how internet gateways, routers and modems — the invisible workhorses of the broadband era — are becoming far more efficient. In 2024, nearly 99% of new devices met the latest Tier 3 energy levels, far surpassing the 90% commitment under the industry’s voluntary agreement.

That achievement is striking given what these devices now do. Today’s SNE is expected to support blazing-fast internet speeds, stronger Wi-Fi signals and the growing number of connected gadgets in our homes. Naturally, those features demand more power. Yet the data shows that manufacturers and providers are finding ways to deliver these capabilities without a proportional surge in energy use.

Perhaps the most telling metric is efficiency relative to broadband speed: Since 2015, the average energy use per unit of internet speed delivered has dropped by 89%. In other words, the boxes in our living rooms and home offices are working harder than ever, but they’re doing it more efficiently.

Weighted Average Ready State Power of New SNE Purchases Relative to Broadband Speeds

Set-Top Box Energy Consumption Continues to Improve

If SNE is the silent partner of the digital home, set-top boxes are the more visible face of our entertainment. The 2024 U.S. Set-Top Box (STB) Report paints an equally successful picture. Back in 2012, digital video recorders (DVRs) were notorious power hogs. But as of 2024, the landscape looks radically different.

• National energy use from set-top boxes has dropped 73%, falling from 32 terawatt-hours in 2012 to just 8.6 TWh in 2024.
• That reduction is the equivalent of shutting down eight traditional 500-megawatt power plants for a year.
• It also equates to a $3.85 billion reduction in electricity costs and avoidance of 15.7 million metric tons of CO2 emissions in 2024 compared to 2012.

Nationwide Annual Energy Used by Set-Top Boxes in the U.S.

The reasons are twofold. First, service providers are deploying fewer set-top boxes overall, as more households switch to streaming services that don’t require them. But second — and just as importantly — the devices themselves are far more efficient. Today’s most common model, the IP-based non-DVR, uses only 26.6 kWh/year, a 78% drop compared to typical set-top boxes from a decade earlier.

Even DVRs now consume less than half the power they did when the agreement began. And for many households, cloud DVR services eliminate the need for a DVR altogether.

The Trends Continue in Canada Too

In Canada, the Canadian Energy Efficiency Voluntary Agreement (CEEVA) shows steady progress in improving the efficiency of set-top boxes and small network equipment.

According to the most recent 2024 independent annual report, 100% of new set-top boxes and 100% of small network equipment purchased met efficiency targets, surpassing the required 90%. This success reflects ongoing collaboration between service providers and manufacturers to deliver devices that use less energy while supporting modern broadband and TV services.

The data shows meaningful progress:

• Since 2017, the energy consumption of new set-top boxes in Canada has dropped 74%:

Weighted Average Energy Consumption of Purchased Set-Top Boxes

• Since 2020, the efficiency of small network equipment in Canada has improved 64% relative to broadband speed.

These impressive declines lower household energy use while maintaining the quality of service customers expect.

Continuing the Commitments

The signatories of these voluntary agreements are committed to continued success. Just recently, both the U.S. STB and SNE VAs extended their terms through 2028 with reports in 2029. More importantly, the SNE VA expanded the VA scope to include fixed wireless access (FWA) devices, increasing the residential market coverage by 13 million more subscribers, and added T-Mobile as a signatory.

The U.S. STB Voluntary Agreement brings together the largest pay-TV providers, manufacturers and energy efficiency advocate ACEEE (American Council for an Energy-Efficient Economy). Similarly, the SNE Voluntary Agreement includes the leading residential internet providers, major equipment manufacturers and Pacific Gas and Electric Company (PG&E) as the efficiency advocate. In Canada, CEEVA signatories include the country’s largest internet and pay-TV service providers and key manufacturers in close collaboration with Natural Resources Canada (NRCan).

CableLabs provides the technical leadership behind the voluntary agreements, working in close partnership with the Consumer Technology Association (CTA) and NCTA – The Internet & Television Association to deliver these measurable results.

Signatories

Why It Matters

Energy efficiency in household electronics doesn’t make headlines the way solar farms do. But the cumulative effect is enormous. Collectively, these voluntary industry agreements have prevented billions of dollars in electricity usage and eliminated hundreds of millions of metric tons of CO2 emissions. They’ve also shown that efficiency and innovation can go hand-in-hand: faster broadband, sharper video, and smarter networks don’t have to mean higher utility bills.

As we spend more time streaming, gaming, and connecting, it’s worth remembering that the invisible progress inside our routers and set-top boxes is part of the bigger climate solution. These improvements underscore how voluntary agreements can drive efficiency gains without compromising performance.

Over the last year, the term agentic AI has become ubiquitous. It’s been described as everything from a personal assistant to a replacement for human workers. In reality, agentic AI is a powerful new form of automation that is most effective when given clear tasks, guided by expert information and integrated with human-in-the-loop workflows to ensure accurate and efficient automation.

In this blog post, we explain how agentic AI is revolutionizing automation by creating systems that don’t just follow pre-programmed rules but understand and adapt to their environment, make informed decisions and take autonomous action to address real-world challenges.

What Is Agentic AI?

Agentic AI is a system composed of multiple AI agents that collaborate to complete complex tasks. Key components include:

• Planner: A planner agent leverages expert information to break down complex tasks into steps that can be distributed among agents, ensuring alignment with organizational and industry best practices.
• Supervisor: A supervisor agent uses the plan identified in the previous step to coordinate work among specialist agents. It determines task completion and manages workflow.
• Specialist: Each agent has a specific role, executing steps in the plan using assigned tools and reporting back to the supervisor.
• Tool calling: Tools are executable functions that enable agents to take autonomous action by connecting AI agents to data sources and performing specific functions.

Enhancing the In-Home Experience

For broadband operators, in-home Wi-Fi issues are a leading driver of customer support calls. It’s difficult for operators to resolve these issues remotely, and sending a field technician is both time-consuming and costly.

CableLabs is developing an agentic AI system to autonomously and proactively detect and resolve in-home network issues, transforming both in-home Wi-Fi management and access network operations — and reducing the number of support calls operators receive. The key components of these systems include:

Continuous Wi-Fi KPI Streaming and Analysis

Using OpenTelemetry and OpenWRT, Wi-Fi KPIs including jitter, latency, airtime utilization and packet loss are collected in real time. Machine learning (ML) models correlate network and application-level KPIs to determine quality of experience.

Wi-Fi Impairment Detection

If degraded performance is detected, ML models identify specific impairments:

• Congestion: Too many devices or applications competing for airtime, leading to higher latency and jitter. In real-time apps like Zoom, this can cause choppy video, skipped frames, audio dropouts or lip-sync issues.
• Signal attenuation: Weak signals from distance or interference, reducing speed and reliability. Devices with a weak signal often transmit at slower speeds (lower Modulation and Coding Scheme, or MCS, rates), consuming more airtime and potentially slowing down the entire network.
• Interference: Competing signals from nearby Wi-Fi networks or non-Wi-Fi devices (like microwaves or Bluetooth) disrupt communication. In apartment or condo buildings, overlapping signals from neighbors’ routers can crowd the airwaves, reducing capacity for everyone.
• Sub-optimal channel selection: The access point remains on or switches to a channel that is already saturated or prone to interference, often due to misconfiguration or poor channel selection logic.
• Coverage gaps (possible access point placement issue): Persistent low signal strength and throughput in certain areas of the home, often caused by the access point (AP) being too far from devices or blocked by walls/furniture. While placement can’t be confirmed from Wi-Fi stats alone, patterns in signal and performance data can indicate that moving the AP may improve coverage.
• Sticky clients: Devices remain connected to a weaker AP or frequency band instead of roaming to a stronger one, causing sustained poor performance. Because the decision to roam is often controlled by the client device, it’s not always possible for the network to force the change. However, by detecting and reporting sticky client behavior, we can provide vendors and device manufacturers with the data they need to adjust roaming logic and improve performance.

Automated Resolutions

AI agents can apply QoS mechanisms automatically to restore performance or notify the user of actions they can take, such as relocating their router or adding a Wi-Fi extender or mesh node.

Detecting and Resolving Access Network Impairments

On the access network side, signal impairment detection remains a challenge, making it harder to resolve issues that degrade a user’s quality of experience. To address this, CableLabs is developing:

Robust Impairment Detection Algorithms

These algorithms analyze upstream and downstream KPIs and data for evidence of impairments. Instead of using hard-coded, deterministic algorithms, machine learning models are trained on robust datasets of upstream and downstream KPIs. Separate ML models are used for impairment detection in each direction, yielding improved accuracy compared to a combined model. This approach, when combined with data from numerous network configurations, ensures that the impairment detection process is robust across multiple operators without needing customization for each network.

Real-Time Telemetry Data Analysis

While machine learning models can be trained on infrequently collected data, the accuracy of these models improves dramatically when data are collected more frequently. Real-time or near real-time data collection produces more accurate impairment detection models and enables real-time or near real-time impairment detection. The ML models must also be lightweight enough to run at the edge to minimize data collection costs and ensure faster impairment detection by eliminating the need to send the data to a centralized location for processing.

Agentic AI Systems for Guided Impairment Resolution

The impairment detection algorithms integrate with agentic AI systems that autonomously collect the upstream and downstream KPIs and perform impairment detection. Once impairments have been identified, the agentic AI system uses expert information to provide step-by-step resolution plans for field technicians. Instead of providing static plans, the system guides field technicians through each step, pulls real-time data from their meters and updates steps based on collected data to ensure accurate and timely impairment resolution.

What Are the Challenges?

Real-Time Data Availability

The ability to obtain real-time, streaming telemetry data from devices on the network is essential to producing accurate impairment detection algorithms, without which the proposed resolutions will not succeed in resolving the quality of experience. While real-time data can be collected from devices on the network, Simple Network Management Protocol (SNMP) is usually the only option for collecting these data but it is not fast enough to support real-time data collection at the scale required for robust impairment detection. Consequently, real-time data streaming must be supported more robustly throughout the industry to enable autonomous impairment detection and quality of experience restoration.

Edge Compute Limitations

Traditionally, edge compute devices in broadband networks, especially customer premises equipment (CPE) such as cable modems and routers, have very limited compute resources. The limited compute capabilities of these devices present challenges to running inference with ML models and small language models (SLMs) on these devices. For lightweight ML models that are not based on neural networks, the compute capabilities of CPE devices are sufficient for performing inference. Some small neural networks and very small SLMs can perform inference with the compute resources on these devices, but larger neural networks and most “edge” SLMs are not capable of running on these compute resources. Additionally, the lack of access to graphic processing units (GPUs) or neural processing units (NPUs) on CPE devices further limits the feasibility of using machine learning models and SLMs for inference at the edge. This is because it results in much slower inference latency compared with GPU- and NPU-enabled models.

Edge Storage Limitations

There is an increasing number of options for SLMs that were designed to function as AI agents on edge devices. These SLMs are small enough to run in compute-limited environments and can typically be run using only CPU instead of requiring at least one GPU; however, the weights for even the smallest of these models exceed 1 GB. Therefore, in addition to requiring sufficient edge compute for low-latency AI agent responses, the edge device must also have sufficient storage to store the weights for these SLMs. While some edge devices have enough storage to hold the weights, the compute and storage capabilities of cable modems and routers are frequently insufficient for these use cases.

Data Privacy and Security

Making real-time, streaming telemetry data available to agentic AI systems at the edge enables real-time impairment detection and autonomous impairment resolution, but it also creates an attack vector and opens questions about data governance and privacy. While edge-hosted SLMs remove concerns about sending sensitive data to cloud large language model (LLM) providers, they open concerns about malicious code being embedded in the model weights and data exfiltration through model response analysis or backdoor attacks. Additionally, careful attention must be paid to how the interfaces that provide access to network data are constructed to prevent unauthorized access and unauthorized actions by the agentic AI system.

The Road Ahead

Agentic AI provides a powerful new form of automation, enabling agents to access and interpret information from their environment and external data sources, determine the appropriate course of action and autonomously take action to resolve issues within their environment.

By leveraging agentic AI at the edge, networks can become self-healing by detecting and resolving impairments autonomously and proactively addressing degradations and potential impairments before they impact subscribers’ quality of experience. In addition to acting autonomously to maintain network quality, agentic AI systems can guide field technicians through the impairment resolution process using expert information from veteran field technicians, reducing the time required to train new field technicians and drastically reducing mean time to resolution for impairments.

Last month’s Hacker Summer Camp brought together hackers, researchers, practitioners and leaders in cybersecurity to review the cutting edge of security research, share tools and techniques, and find out what’s at the front of everyone’s mind in the security space.

So, what was at the forefront of the conversation this year in Las Vegas, and what trends in cybersecurity do you need to be aware of?

We outline our takeaways from Black Hat USA and DEF CON in a new CableLabs technical brief, available exclusively for our member operators. We’ll also dive into the conferences further during a members-only webinar on Wednesday, Sept. 17. Members can register here to join us.

For now, some of our high-level insights are summarized here.

What’s Old Is New Again: Hacking Like It’s the 90s

With the rapid adoption of tooling like generative AI and its agentic variants, the implications of overlooking the basics in security are more impactful than ever. Many different presentations at Hacker Summer Camp focused on this theme, in which researchers consistently demonstrated how classic cyberattacks are still thriving, now applied to modern contexts like agentic AI. The takeaway? AI-centric software is still software; thus, the basics apply: applying least privilege, separation of interests, thorough input sanitization and more.

AI: Your New, Non-Deterministic, Insecure Execution Environment

Unsurprisingly, AI remains at the forefront of the discussion. Novel from recent years was the notion that AI is no longer simply a chatbot interface added to your architecture, but a whole new execution environment. Many presentations and demonstrations showcased how large language model (LLM)-powered applications and agentic AI constructions can be abused or confused, with several undesirable outcomes. While there’s a great deal of work to be done to secure emerging AI technologies, many strategies for mitigating attacks were recommended. AI is being adopted in cybersecurity too, from both the adversarial and defender perspectives, which makes it clear that another cybersecurity arms race is underway.

Automation Pitfalls: Deploy Fast, Break Faster — With a Bigger Blast Radius

Automation tooling, such as continuous integration and continuous delivery (CI/CD), took center stage for many discussions, where simple and subtle misconfigurations resulted in significant consequences, from initial access and lateral movement. With one of the killer use cases of agentic AI being coding assistants and source code reviews, today’s relationship between AI and automation tooling is a close one. The aforementioned attack surface of those AI components thus has direct implication to that of the automation tooling.

Initial Access: CI/CD, Developers and Supply Chain Attacks

Finally, the conferences this year demonstrated the increasing burden of developers to act as bastions of security. However, the attack surface faced by the average developer is also increasing. This is due in part to the addition and management of AI assistants with access to code as well as the use of plugins for Integrated Developer Environments (IDEs) like Visual Studio Code that are ubiquitous across the industry. Developers and the tools they interact with are increasingly valuable for adversaries to target, creating opportunities for initial access and even executing supply chain attacks.

Cybersecurity Evolution Continues Moving Forward

Hacker Summer Camp 2025 made it clear that the rapid shifts we’re seeing in technologies like AI have left significant gaps in ensuring that the basics of security remain covered. It also demonstrated that cybersecurity professionals and enthusiasts are doing the work required to address those gaps, as well as adopting new and adapting classic approaches to bolster cybersecurity controls.

Register for TechExpo25 today to connect with global operators, policymakers, vendors and innovators next month in Washington, D.C., and join the conversations shaping the industry’s future.

The broadband industry is preparing to bid farewell to one of its most influential leaders. Michael Powell's retirement from NCTA – The Internet and Television Association caps a distinguished tenure marked by revolutionary policy innovation and unwavering commitment to increasing access and advancing connectivity for all Americans — a transformative chapter that paves the way for continued progress.

As the former chairman of the Federal Communications Commission (FCC), Michael brought a unique perspective to policy shifts in the industry. Over the past 15 years as president and CEO of NCTA, he has advocated for policies that support innovation, helping to shape the future of connectivity.

Michael announced his retirement in February. This week, NCTA announced the appointment of his successor, former U.S. Sen. Cory Gardner, who represented Colorado in the Senate from 2015 to 2021 and in the U.S. House from 2011 to 2015. He will officially join the association later this month.

Champion of Broadband Access and Innovation

Michael has been called a champion of the industry by many, but his vision for the future of connectivity extends far beyond traditional broadband infrastructure.

He has been a steadfast industry ally throughout his career, first as FCC chairman, fighting battles over Title II broadband regulations, and later as president and CEO of NCTA, where he has led some of the most significant efforts toward seamless connectivity through the 10G initiative.

Michael’s advocacy for the 10G initiative — which enables widespread seamless connectivity and enables technologies that will fundamentally change how we live, work, learn and play — exemplifies his commitment to pushing the boundaries of what's possible in broadband technology. Advocating for improved speed, access and reliability for all, Michael has described 10G as “not the picture, (but the) canvas on which the demands of our imagination will be built,” underscoring the massive opportunities for innovation such a network can offer.

His ability to recognize future connectivity needs and champion the policies to make them reality has been invaluable. When the COVID-19 pandemic accelerated the need for reliable, secure and fast connectivity, the broadband industry showed it was not only ready but performed exceptionally well. Michael’s efforts and contributions to the 10G initiative helped move us forward into the connectivity that we know today and set the stage for the innovations that will drive our future.

His work with the initiative is foundational to the Technology Vision for the future of the industry, the next generation of connectivity innovation.

Spectrum Leadership and Wi-Fi Advocacy

Michael’s tireless advocacy for unlicensed spectrum and innovative solutions to unlock these wireless resources has been instrumental in shaping the industry's future. His support for spectrum sharing solutions like Citizens Broadband Radio Service (CBRS) has increased access to critical spectrum resources, enabling additional mobile capacity to enhance consumer choice in mobile services while extending high-speed internet access to Americans in rural and underserved areas.

Earlier this year, Michael testified before the House Energy & Commerce Committee, advocating for a more comprehensive approach to spectrum management and emphasizing its essential role in maintaining America's economic and technological leadership. He argued that efficient spectrum use is fundamental to the country's competitive advantage in the global marketplace.

Michael’s advocacy stems from his conviction that “Wi-Fi is more than just convenience — it's a game-changer for our economy and innovation.”

The CableLabs Connection

For many years, Michael has served as a non-voting member of the board of directors at CableLabs. Michael’s policy work and vision for "permissionless innovation" — the idea that individuals and companies should be able to experiment and innovate with new technologies without extensive regulatory barriers — is a philosophy that has guided much of his work and helped create an environment where breakthrough technologies can flourish.

CableLabs President and CEO Phil McKinney reflects on Michael’s impact:

"We at CableLabs are immensely grateful for Michael’s leadership and advocacy. He has certainly contributed to our ability to innovate and build the networks of the future.

"He has been a guiding light on policy in the broadband industry and has brought us to where we are today. Michael has an uncanny ability to balance competing interests, promote innovation and navigate complex government and policy issues.

"The foundations he has laid will continue to benefit all of us for years to come. We’re all stronger, more innovative and better positioned for the future because of his efforts.”

Michael — who was inducted into the Broadcasting & Cable Hall of Fame in 2016 and the Cable Hall of Fame in 2022 — leaves a legacy of impact that will continue to position America as an economic and technology leader far into the future. CableLabs is grateful for his efforts and wishes him success and happiness in his well-deserved retirement.

CableLabs engineers and technologists are actively contributing to the Reference Design Kit for Broadband (RDK-B), an open-source software platform deployed by many CableLabs member companies to power connected home experiences. RDK-B forms the foundation for key residential gateway features, including set-top box (STB) integration, IoT device management and managed Wi-Fi in both single-family homes and multi-dwelling units (MDUs).

As a vendor-neutral, open-source software stack, RDK-B offers operators flexibility, transparency and control over their broadband infrastructure — values that align closely with CableLabs’ mission to drive interoperable innovation at scale.

Elevating Mesh Networking with EasyMesh

In 2024, the RDK-B community launched a major initiative to integrate support for Wi-Fi Alliance’s Wi-Fi CERTIFIED EasyMesh™ standard — prompting CableLabs to get directly involved. As longstanding contributors to the Wi-Fi EasyMesh specification, CableLabs is uniquely positioned to enhance RDK-B’s implementation and help ensure seamless, vendor-agnostic mesh networking experiences for operators and their subscribers.

Wi-Fi EasyMesh represents a significant evolution in home networking. Unlike proprietary mesh solutions, Wi-Fi EasyMesh is an open standard, enabling multi-vendor interoperability among access points, extenders and controllers. This is particularly important for operators looking to break free from vertically integrated, locked-in ecosystems that limit flexibility and slow innovation.

By standardizing mesh behavior — including topology formation, channel management and band steering — Wi-Fi EasyMesh gives operators a common framework to manage and optimize Wi-Fi networks across diverse hardware. It also opens the door for competitive procurement, reduced vendor dependency and consistent user experiences across device brands and firmware versions.

Advancing Wi-Fi Easy Connect and Seamless Onboarding

CableLabs’ first major upstream contribution to RDK-B was the industry’s first fully open-source implementation of the Wi-Fi Alliance’s Wi-Fi CERTIFIED Easy Connect™ protocol, also known as the Device Provisioning Protocol (DPP). This milestone brings support for Zero-Touch Onboarding (ZTO) to RDK-B, enabling secure, user-friendly network enrollment via QR code — without requiring users to know or input Wi-Fi credentials.

DPP is particularly well-suited to modern mesh deployments, where adding new devices (e.g., access points, IoT endpoints, controllers) needs to be fast, secure and reliable. With Wi-Fi Easy Connect now part of the RDK-B Wi-Fi EasyMesh stack, operators can deliver a smoother out-of-the-box experience for end users while enhancing network security through modern cryptographic provisioning methods. Again, CableLabs is uniquely positioned to contribute Wi-Fi Easy Connect functionality due to our continuing leadership and contributions to the specification during its development in Wi-Fi Alliance.

CableLabs publicly showcased the integration at RDK Summit 2025 in London, where I gave a featured technical talk highlighting the importance of seamless and secure onboarding in connected home environments. Simultaneously, my colleague Ben Carlson hosted a live demonstration booth, offering hands-on insight into CableLabs’ open-source contributions and their impact on RDK-B’s capabilities.

Strategic Synergy Between CableLabs and RDK-B

The collaboration between CableLabs and the RDK-B community represents a natural synergy. Both ecosystems are built around the values of interoperability, openness and scalable innovation. RDK-B provides a robust deployment vehicle, and CableLabs brings a deep well of standards leadership, cross-industry coordination and forward-looking technology development.

By contributing directly to RDK-B, CableLabs can help ensure that its latest innovations — many of which are defined in collaboration with operators, original equipment manufacturers (OEMs) and global standards bodies — are production-ready and deployable across member networks. The result is a faster path from spec to field deployment, enabling member companies to move with greater agility and confidence.

RDK-B also benefits from CableLabs’ neutrality and long-term vision. Our work with Wi-Fi EasyMesh, Wi-Fi Easy Connect and the broader Wi-Fi ecosystem is guided by industry consensus and technical rigor, helping RDK-B implementations remain future-proof and aligned with operator priorities.

RDK-B as a Strategic Distribution Platform

Because RDK-B serves as the networking software platform for many CableLabs members, it offers a compelling vehicle for delivering and scaling future innovations across the broadband ecosystem. Beyond Wi-Fi EasyMesh and Wi-Fi Easy Connect, CableLabs is actively exploring opportunities to leverage RDK-B for deployment of:

• Low Latency, Low Loss, Scalable Throughput (L4S)
• Wi-Fi CERTIFIED Data Elements™ for advanced telemetry
• Enhanced security and diagnostics capabilities
• Multi-access and hybrid access techniques
• Additional next-generation technologies in development

By aligning closely with the RDK-B community and contributing robust, standards-based enhancements, CableLabs is helping ensure that our members have access to a secure, flexible and future-ready broadband platform — one that evolves in tandem with the needs of modern connected households.

Together, RDK-B and CableLabs are building the foundation for the next generation of broadband. If you use the RDK-B platform, be on the lookout for these and other new features.

The latest DOCSIS® 4.0 interop event wasn’t just another gathering of broadband innovators — it was another significant step forward for the industry.

With more than 50 attendees from around the globe, the energy in the room was palpable. This event wasn’t just about checking boxes for protocol compliance; it was about pushing the limits of broadband technology and seeing what happens when the brightest minds and the fastest modems in the business are brought together at CableLabs.

The Interop·Labs event, held Aug. 11–14 at CableLabs headquarters, gave suppliers an opportunity to verify interoperability between equipment designed to comply with DOCSIS 4.0 specifications. It focused on three key areas: speed, stability and a diverse ecosystem. Each of these components directly impacts the quality and reliability of broadband service.

Ten Modem Suppliers, One Goal

One of the standout aspects of this interop was the 10 participating modem suppliers. Each supplier brought their own unique hardware and firmware optimizations to the table, creating an environment where innovation could thrive.

Once again, attendance at the event was the highest yet and included three operators on hand to observe demos and share their DOCSIS 4.0 network progress.

Three suppliers — CommScope, Harmonic and Vecima — brought DOCSIS 4.0 cores to the event. Again, we saw five Remote PHY Device (RPD) platforms from Calian, CommScope, Harmonic, Teleste and Vecima. And, of course, the icing on the cake was the number of DOCSIS 4.0 modem suppliers in attendance — Arcadyan, Askey, Compal, Gemtek, Hitron, Sagemcom, Sercomm, Ubee, Vantiva and WNC — who brought multiple modem models.

Chipmakers Broadcom and MaxLinear brought local engineering support for their cable modem partners, and Calian participated with its test solutions.

Every supplier was aligned on one common goal: proving that DOCSIS 4.0 technology is not simply a theoretical leap forward but that it is a commercially viable technology ready for wide-scale rollout. The interoperability tests weren’t simply about passing; they were about performance headroom, feature robustness and forward-compatibility.

And the results? Let’s just say fast doesn’t even begin to describe it.

The Showstopper: 16 Gbps Downstream

If there was a single number everyone walked away talking about, it was 16 Gbps downstream. Achieving this kind of throughput in a lab environment is one thing; demonstrating it live in a collaborative interop environment — across multiple suppliers — is something else entirely.

This wasn’t an isolated “best case” setup either. Several configurations reached double-digit gigabit speeds, showing that DOCSIS 4.0 technology isn’t just an incremental step — it’s a foundation for multigigabit service tiers that can compete head-to-head with fiber.

Collaboration Is the New Competition

Perhaps the most inspiring part of the event wasn’t the hardware or the speed tests — it was the culture of collaboration. Ten different modem suppliers, each with their own market goals, came together to ensure that when DOCSIS 4.0 technology hits the field, it will work seamlessly across the ecosystem. The modems spent most of the interop working on the three cores, driving interoperability across the wider ecosystem with the RPD suppliers.

This spirit of cooperation ensures that innovation isn’t locked in silos. When suppliers solve interoperability challenges together, operators and consumers benefit from a smoother, faster rollout of next-gen services.

Additional Cable Modem PNM Operations

With a record number of modems in attendance, we rolled out the proactive network maintenance (PNM) tests for the modems. More and more, the signals on the plant are orthogonal frequency division multiplexing (OFDM) and orthogonal frequency division multiple access (OFDMA), which provide higher speeds and capacities than traditional quadrature amplitude modulation (QAM) signals.

At this interop, we ran five PNM tests on the modems, specifically getting data from DOCSIS 4.0 modems and verifying interoperability with the application programming interfaces (APIs) and with the data generated by the modems. This PNM data will enable the most efficient operation of the coaxial cable network, keeping the data levels at their peak by using the more efficient OFDM and OFDMA signals.

DOCSIS 3.1 Plus: Beyond the Buzzword

DOCSIS 3.1 Plus (DOCSIS 3.1+) was also prominent at the interop with several modems in attendance. The leap from DOCSIS 3.1 to DOCSIS 3.1+ is about raw speed. The “Plus” brings expanded support for more OFDM channels, which means more downstream speed. More than slides in a presentation, these advancements were tested, measured and verified in real time.

Operators are already discussing how these capabilities could fit into their network evolution plans. With the cost efficiency of leveraging existing HFC plant and the performance benefits on display, DOCSIS 3.1+ has emerged as a compelling strategy for rapid, wide-scale multigigabit deployment.

What’s Next

With the success of this record-breaking interop, the stage is set for even more ambitious goals. The industry now has proof that multi-vendor DOCSIS 4.0 systems can deliver and play nicely together. The next steps will likely include refining firmware for even better efficiency and starting the migration path toward DOCSIS 4.0 technology.

There are lots of moving parts in these interops, but one thing is certain: the 16 Gbps milestone will be remembered not just for the number but for what it represents — the moment when the industry saw the future of HFC networks and realized it was already within reach.

This interop wasn’t just an event — it was a benchmark for the broadband industry’s future. With record attendance, diverse vendor participation and real-world proof of DOCSIS 4.0 capabilities, the path to multigigabit broadband has never been clearer.

Another DOCSIS 4.0 interop is planned for the week of Oct. 20 at CableLabs. Consider joining us to see the speed and service possibilities firsthand!
