From Inspiration to Pitch: How Innovation Boot Camp Launched the Idea for ARC HotSpot

CableLabs Innovation Boot Camp


Mar 21, 2023

Innovation isn’t just about creating new products. It’s about bringing together diverse thoughts, perspectives and experiences to solve big problems. At Innovation Boot Camp, CableLabs members and employees work together in an intimidation-free zone to immerse themselves in the innovative process, from inspiration to final pitch.

During the week of April 24–28, 2023, CableLabs will host the 20th Innovation Boot Camp, where innovators will receive hands-on experience and live coaching from CableLabs CEO Phil McKinney and other expert speakers and coaches. In this spring’s all-virtual format, participants will learn the FIRE framework (Focus, Ideation, Ranking, and Execution), experience the innovation process end to end; and learn strategies that they can apply to their own teams and projects immediately.

It’s an inspiring environment designed to bring the industry closer together and share new ways of creating and innovating.

But do any of the ideas developed at Innovation Boot Camp actually make it to market? Yes, they do.

A Market-Ready Solution to a Real-World Problem

Innovation Boot Camp pulls out all the stops to help participants tackle real issues that they’re facing in their businesses or other contexts. The innovative process we teach is designed to generate ideas that result in viable solutions, many of which have gone on to production.

One of those ideas was Kyrio’s ARC HotSpot, a technology that delivers automated failover for broadband networks. The idea for ARC HotSpot was born out of the 2020 Innovation Boot Camp, which took place during the COVID-19 pandemic, when companies urgently needed reliable remote-work solutions. By holding the very first virtual Innovation Boot Camp in the midst of this new world of work, CableLabs gave participants an opportunity to collaborate and innovate despite lockdown restrictions.

The challenge of the 2020 Innovation Boot Camp was to come up with a technology idea that would make working from home a better experience. Participants learned from veteran coaches, then broke into teams to begin the ideation process. One of those teams was Team Echo, which consisted of CableLabs employees from various backgrounds and areas of expertise, including CableLabs’ Director of Procurement Zen Mykytyn.

During a brainstorming session, Zen observed that one of the most difficult challenges of navigating virtual work and school was keeping everyone connected during a service outage. With two parents working from home and kids logged in to Zoom classrooms, even a short outage resulted in house-wide panic as meetings were disrupted and no one could do their work.

But what if there was a technology that could solve that problem?

Zen’s observation was the spark that launched a week of brainstorming, iterating, investigating and developing the idea that eventually became ARC HotSpot.

From Inspiration to Pitch

With the idea in hand, Zen and the other members of Team Echo started developing a solution. Coached by John Bahr, the team came up with the idea of using a smartphone as a hotspot for the entire home network. They conducted a live customer experience conversation to get real feedback on the idea, put together a one-sheet and a storyboard, and developed a pitch that they would present to the Innovation Boot Camp panel at the end of the week.

“CableLabs’ Innovation Boot Camp, while a fun learning experience, is also a place where game-changing ideas happen,” said coach John Bahr. “My team came up with a solution to a problem that was at the forefront of real customers’ minds during the height of the COVID-19 lockdown. Executing on that solution to turn it into a real product was just so cool!”

At the end of the week, Team Echo pitched their idea over Zoom. Just a few short minutes after Zen began presenting, his connection dropped. One of the other team members picked up the pitch as everyone waited for Zen to re-establish his connection. It was a brilliant, planned demonstration of the exact use case that made the team’s idea so relevant, and the panel agreed it was an idea worth pursuing.

After Innovation Boot Camp ended, John Bahr gave a demonstration that generated significant interest. Kyrio non-exclusively licensed the intellectual property from CableLabs and developed its own implementation, and ARC HotSpot was born.

Innovation Is a Team Sport

Zen strongly believes that the positive, nurturing environment of Innovation Boot Camp and the diversity of the team made it possible for his idea to come to fruition.

“My team included John Bahr, Greg White and Mark Bridges,” he said. “They’re all really smart guys and experts in their fields, but they’re all different. My field isn’t technical thinking or awareness, but working with them gave me a glimpse into what they do every day and how they think. My idea wouldn’t have come to be without the rest of the team.”

That diversity of experience lies at the heart of Innovation Boot Camp’s mission. We believe that great ideas can come from anywhere—and they do. Innovation is a team sport that thrives when diverse thinkers come together in an intimidation-free environment to make things better.

If you’re looking for a hands-on experience that puts words and ideas into action, Innovation Boot Camp is ideal for you. You’ll learn to challenge your thinking, develop new skills and put those skills into action as you work with a team of other innovators.

Ready to see what it’s all about? Join us for the next CableLabs Innovation Boot Camp. Spots are limited, and innovation topics do vary.

Step Inside the Future: Experience Exhilarating Virtual Worlds with Immersive Technology

Step Inside the Future


Mar 7, 2023

How we experience the digital world is about to get a whole lot more exciting. The newest film in the “Near Future” series shows what a day in the life of a family looks like as technology transforms how they work, study and engage with each other. Imagine interacting with virtual people and places that feel real and propel you into new worlds. This is the future that the “Step Inside” film explores—and it’s not that far off.

Immersive Media

In the film, a virtual 3D talking rabbit and a lifelike prowling tiger enhance the children’s learning and play through an immersive experience. With holographic and light field technologies, characters come to life with realistic depth and presence so that the family can interact with them.

Light Field Displays

Imagine 3D displays that don’t require special glasses or headsets. This is what the main character, Clara, experiences when she’s in the meeting with her investors and they can exchange glances. With light field technology, multiple people can view the same thing at the same time using displays on walls, tabletops or even entire stage floors.

Holographic Telepresence

As Clara is briefed on a developing hurricane, she and her remote team can observe the storm’s pathway simultaneously via a life-size holographic projection. Holographic telepresence technology allows multiple users to experience the same three-dimensional media at the same time and from different angles. Clara also presents remotely to her board members as if they are all in the same room together. With holographic telepresence, it’s easier to build bonds and create deeper connections. These holograms are three-dimensional images formed by the interference of light beams from lasers or other light sources.

Advanced AI Avatars

In the film, Clara’s assistant helps her prepare for her presentation and also sees she’s nervous and provides her with guidance to calm her. AI avatars are digital representations of a human in a virtual setting powered by artificial intelligence. These avatars can take the form of a multitude of personas that are capable of authentic, human-like communication and designed to educate, guide and entertain us.

AR Smart Glasses

Ben and Clara take their avatars on the go with technologically sophisticated glasses that look like the eyewear many of us wear today. The difference? AR smart glasses will bridge our real-world experiences with our digital lives. Instead of head-mounted displays (HMDs), the sleek smart glasses of the future will allow us to interact with digital objects and information overlays directly within our field of vision.

Quantum Computing

Clara is with her team watching the developing hurricane. Quantum computing is powering the highly detailed storm analytics. In Clara’s case, this technology reroutes the ships, potentially saving lives and the business. With quantum, computers can simulate complex scenarios and optimize advantageous outcomes faster than classical computers.

What’s Next?

Each of these innovations is already in development, paving the way for our next-generation experiences. CableLabs is at the forefront of what’s new and next, innovating today for the broadband of tomorrow.

How 3GPP Is Fostering Network Transformation for Edge Compute

Edge Compute Applications

Arun Yerra
Principal Mobile Network Architect

Feb 27, 2023

Edge computing is expected to grow tremendously in the near term—between 40 and 70 percent by 2028. In the short term, cloud-native applications deployed closer to client devices will be used to solve edge use cases. In the long term, edge computing infrastructure demand will be driven by edge-native use cases—such as augmented reality (AR)/extended reality (XR), autonomous vehicles and vehicle-to-everything (V2X) communications—that can only function when edge computing infrastructure capabilities are available.

Edge computing applications need last-mile networks that can support stringent requirements for end-to-end network latency, jitter, bandwidth, application-specific quality of service (QoS), reliability and availability. Challenges in edge networking go beyond latency and jitter. The network should support local breakout, dynamic insertion of data network attachment points and dynamic traffic steering.

Solving these challenges is important because edge computing will be a key driver in transforming mobile network operator (MNO) and multiple system operator (MSO) networks. Edge computing applications will gain a foothold in markets—including manufacturing, health care and retail—as well as benefit residential and mobile customers through smart home technologies, streaming services and content delivery, and virtual reality (VR) and AR.

Because last-mile networks are owned by communication service providers (CSPs) like MNOs and MSOs, these operators are well suited to play an essential role in edge compute infrastructure. They also own a lot of real estate and infrastructure, allowing them to host edge compute servers closer to the end user. Collaboration among hyperscalers, CSPs, edge service providers and edge application developers is essential for wider adoption of edge computing.

The Mobile Broadband Standard Partnership Project (3GPP) and partner organizations such as ETSI and GSMA are developing standards for defining network architecture and edge compute application architecture so that vendors can develop interoperable edge infrastructure and applications.

Edge-Compute Infrastructure Transformation

Transforming the applications and CSP infrastructure to support edge compute use cases can happen in two distinct stages based on short-term and long-term use cases. The first stage involves upgrading existing provider networks to be edge compute–ready so that cloud-native applications can support edge compute use cases without any edge infrastructure awareness. Edge-unaware applications are cloud-native applications that need to support an edge compute use case but aren’t capable of interfacing with edge compute infrastructure.

The second stage involves developing brand-new edge compute–aware applications capable of solving edge use cases. Edge-aware applications can utilize edge compute infrastructure features and APIs to optimize the connectivity between clients and servers so that they can support stringent service requirements of edge compute use cases.

In this blog post—the first in a two-part series—I’ll discuss 3GPP initiatives that support CSP network transformation, which will enable cloud-native, edge-unaware applications supporting edge compute use cases. In a later blog post, I’ll talk about the 3GPP SA6 edge app architecture that defined a framework for edge-aware applications to support edge-native use cases, such as AR/VR, V2X and so on.

5G System Transformation for Edge Compute

One of the main requirements of edge compute applications is to connect the most optimal application server instance to the client device satisfying latency requirements. An edge application typically will be hosted on a distributed cluster of application servers that are deployed in multiple data centers connected to a CSP network.

The 3GPP SA2 working group has defined procedures to discover the optimal server. The procedures involve resolving the application server’s fully qualified domain name (FQDN) to a server instance that is closest to the client device. SA2 introduced a new network function and procedures that intercept the Domain Name System (DNS) requests sent by the client for server FQDN resolution. This allows the network to redirect the DNS request to a data network—or, more specifically, a DNS server within the data network—that hosts the application server closest to the client. The Session Management Function (SMF) within the CSP core network plays a critical role in application server discovery. The SMF identifies the data network and local DNS server that resolves the application server FQDN based on the client device location.

SA2 introduced a new network function called Edge Application Server Discovery Function (EASDF), which is configured as a DNS resolver in the user equipment (UE). The EASDF sends a copy of DNS messages to the SMF for it to select a data network. To perform DNS server selection or data network selection, the SMF needs to learn all the Edge Application Servers (EASs) deployed in the data networks. The EAS information includes data network identification, EAS FQDNs, EAS IP addresses and the DNS server. CSPs push EAS deployment information to the network using Network Exposure Function (NEF) northbound APIs, whenever they deploy an EAS.

Edge Service Provisioning

Edge Service Provisioning

The edge service provisioning process includes the discovery of an optimal edge server. SA2 modified the Protocol Data Unit (PDU) session establishment procedure between client device and SMF to enable edge service provisioning. During the PDU session establishment, the SMF configures the EASDF as a DNS resolver on the client device through a protocol configuration option. The SMF also creates client device–specific DNS context that includes DNS rules in the EASDF so that the EASDF copies the DNS requests that the client device sent to the SMF. The copy of the matching DNS query messages from the client device will be sent to the SMF.

The SMF selects the DNS server to resolve the FQDN based on the client device location. The SMF informs the EASDF of the selected DNS server, and the EASDF forwards the cached request to the DNS server that the SMF selected. Similarly, the EASDF will match the DNS response from the DNS server against the DNS rules, and it may send the copy of the DNS response to the SMF. The SMF may dynamically insert a local PDU session anchor and Up Link classifier to steer traffic to the data network that hosts the application server if needed.

Edge Relocation

Edge relocation refers to the process of selecting and connecting to a new application server when the current application server becomes suboptimal. This happens if the client device moves to a new location or if available compute and network resources become too low.

This process completes the server transition with minimal service interruption. The edge relocation process within 5GS relies on 5GS service continuity procedures that are defined for UE roaming scenarios. Procedures for 5GS SA2 edge relocation can support only the client device mobility scenario, not the application server compute and network resource availability.

3GPP 5GS defines three service continuity modes, and 5GS can support edge relocation in SSC Mode-2 and SSC Mode-3 because a new PDU session is established in both these modes. Whenever a new PDU session is established, the client device will initiate a DNS query to resolve the application server FQDN. The network will discover the most optimal server based on the client device location, as mentioned above in the edge service provisioning procedure.

What's Next?

SA2 network architecture defines extensions to 3GPP 5G system architecture to enable edge-unaware applications to support edge compute use cases. These extensions help applications discover the optimal application server based on the client device location by resolving server FQDN to the closest application server by proximity. But optimal application server discovery based on other KPIs—such as compute resources, network resources, capabilities and so on—requires edge-native applications. The 3GPP SA6 working group defined an edge application framework to match application client KPIs with EAS capabilities to select the most optimal EAS.

Transformation of the CSP network is required to support edge-native use cases like AR/VR. The network transformation happens gradually by supporting edge-unaware applications initially and, later, supporting edge-native applications that require more stringent network KPIs.

  2023 Technology Predictions

2023 Technology Predictions

Phil McKinney
President & CEO

Jan 31, 2023

Technology impacts us in every way, touching our lives, businesses and communities. Over the last few years, we’ve experienced a major transformation in how we work and collaborate, which has introduced many benefits and challenges. But with adversity comes opportunity and innovation.

Some of the problems this year’s technology predictions aim to solve are an increased need for remote collaboration, flexible and efficient transportation, personalized technology and secure networks. The possibilities lying ahead are nearly limitless, and our annual tech predictions envision the development of technologies that will define our future.

Remote Work Becomes Serendipitous

We’ve increasingly become a culture that values the flexibility to work from anywhere. For many of us, that means working remotely or at least working in a hybrid environment. New technologies are enabling us to connect in serendipitous ways, leading to meaningful, chance encounters at the right place and time—like when we bump into a colleague in the hallway and the interaction sparks a new idea.

Now, cutting-edge technologies like virtual reality, holograms and smart glasses will transport us into augmented or virtual reality environments that feel real. These new technologies offer us flexibility and opportunities to connect in new ways, making remote work more collaborative. Other benefits include faster training and onboarding, and the need for less physical office space. These augmented and virtual reality innovations may even lead to increased happiness at work.

Autonomous Vehicles Revolutionize Transportation

Buckle up. We’re on the brink of a transportation revolution.

Autonomous vehicles are about to change the way we get around. Today, we understand that autonomous vehicles drive themselves without any intervention by humans other than them defining the destination. The trend toward safer, sustainable and possibly more equitable transportation systems is evolving.

Autonomous vehicles will contribute to lives saved, reduced traffic congestion and less pollution. An economic impact will be felt, too, with autonomous vehicles popular among those who don’t have a driver’s license or who live in areas with poor public transportation options.

It’s not a matter of if this new technology will be integrated into our transportation system—it’s a matter of how and when.

AI Becomes Personal

Artificial intelligence is here to stay and getting smarter every day. As a result, we can expect to see growth in AI as a personal aid in creativity and in health and wellness.

AI has evolved to be easily accessible in a variety of ways, especially because many tools are now open-source. Your favorite apps may even be powered by some form of AI-augmented tools to assist art and music creators. With this increased accessibility, AI has transformed health care for drug development, robotic surgery and telemedicine. As more data is collected and moved to the cloud, we’ll see more personalized services, including smart nurse bots, online health coaches and remote care assistance.

This increased accessibility to health care will be especially beneficial in rural areas and developing countries, and more self-service options will allow people to take better control of their health.

Quantum Networks Become Tangible

Quantum networks are the next step in secure communications. Bolstered by the promise of near-zero latency, elimination of physical network infrastructure and unhackable communications, quantum networks will make it possible to detect with certainty when communications have been intercepted. The networks use quantum phenomena such as superposition, no-cloning and entanglement that are not available in today’s broadband and wireless networks.

Research and investment in quantum networks are already accelerating as companies and governments around the world set up research labs to build large-scale quantum networks. This growth is paving the way for practical applications of the technology to transmit sensitive data and communications.

Defining Our Future

Whether transforming the future of work, enhancing transportation systems, augmenting our creativity or improving communications, technological advancements are addressing some of the most pressing issues of our time. I believe we’ll see some fantastic projects and products launched in 2023. Watch my video below to learn more about these technology predictions.



Charged Up and Gaining Ground: Global PlugFest Moves Open RAN Ecosystem Closer to Commercial Deployment

O-RAN Global PlugFest

Spiros Kapoulas
Principal RAN Architect

Jan 30, 2023

Service providers constantly reconsider their network architectures in search of economies of scale and new business model opportunities, keeping a close eye on open network architectures. Taking advantage of the continuous decoupling of hardware and software, the mobile industry has been working on a software-defined open radio access network (RAN) initiative called Open RAN.

What exactly is Open RAN? What does it mean for wireless network technologies? Finally, how is CableLabs actively involved in the initiative?

What Is Open RAN?

Open RAN is an open set of technical networking specifications realizing open interfaces and network programmability. The initiative enables mobile operators to deploy intelligence closer to where it's needed, whether at the antenna or at edge of a network, to improve operational efficiency and quickly adapt to new service models.

Open networking is also getting attention from governments. On Dec. 8, 2022, the governments of the United States, the United Kingdom, Australia and Canada announced in a joint statement the endorsement of these Open RAN principles:

  • Open disaggregation
  • Standards-based compliance
  • Demonstrated interoperability
  • Implementation neutrality

To demonstrate the principles in action, the O-RAN Alliance—a group of mobile operators, vendors, and research and academic institutions—has been holding bi-annual Global PlugFests.

O-RAN Global PlugFest

CableLabs was one of six hosts for the Fall 2022 O-RAN Global PlugFest. During the PlugFest, the Kyrio Open Test and Integration Lab—located at our main offices in Louisville, Colorado—made its state-of-the-art 5G facilities available to network and test equipment vendors. Overall, we observed that Open RAN equipment from various vendors can interpret the open standards correctly and interoperate successfully under load conditions, paving the path toward commercial deployments.

Seven participants—Calnex, Capgemini Engineering, Lumentum, Radisys, Sunwave, VIAVI and Xena Networks—collaborated, integrated and tested three scenarios to demonstrate interoperability based on open interfaces implementation. Specifically, the companies tested:

  • Multi-vendor Open RAN system integration and end-to-end system performance using 5G user equipment (UE) and 5G Core network emulators. The Open RAN system consisted of Centralized Unit (CU), Distributed Unit (DU) and Radio Unit (RU) components interconnected via third-party small form-factor pluggable (SFP). Upon successful integration, the participants measured the fronthaul latency impact on peak user throughput and cell throughput under various signaling and user traffic load conditions.
  • The interoperability of Open Midhaul (F1) and Xn interfaces for an Open Centralized Unit (O-CU) that adheres to the CU-DU Split gNB architecture defined in 3GPP. Both interface management and UE-context related procedures were verified.
  • Near-Real-Time Radio Interface Controller (Near-RT RIC) integration and testing with RIC Tester. The Open RAN E2 interface procedures, used to enable near-real-time software applications for network automation (xApps), were verified against an emulated 5G RAN. In addition, a QoS xApp was successfully integrated.

For more information about the fall event, visit the O-RAN Global PlugFest web page.

O-RAN Global PlugFest

Ongoing Interoperability Work

The Fall 2022 O-RAN Global PlugFest event was just another way CableLabs works with the industry and vendors to drive interoperable network technologies.

Also last year, CableLabs was recognized for its interoperability testing in mobile network technologies when it was named the host lab for the 5G Challenge’s Preliminary Event. The challenge was hosted by the National Telecommunications and Information Administration’s (NTIA’s) Institute for Telecommunication Sciences in collaboration with the U.S. Department of Defense.

In addition, Kyrio—a CableLabs subsidiary—provides Open RAN certification and badging testing services (conformance, interoperability, end-to-end) for those who want to certify their Open RAN component or system on their own time at their own pace. If you're interested in Kyrio’s testing services, learn more or contact the team.

What’s Next for Open RAN?

The fall PlugFest event allowed the industry to get the pulse of the Open RAN ecosystem. And our work continues.

CableLabs and Kyrio plan to continue hosting O-RAN PlugFest activities at our Kyrio OTIC lab. In the future, we'll be exploring innovative radio network implementations based on the Open RAN architecture. We welcome CableLabs members, vendors and application developers to join us at these upcoming events. To register your interest in participating, contact us using the button below.

Demonstrated by multiple operators and supporting equipment providers at the CableLabs 10G Showcase, DOCSIS® 4.0 technology is capable of supporting 9 Gbps downstream capacity and 6 Gbps upstream capacity today. This confirmation that hybrid optical nodes support both DOCSIS 4.0 technology and EPON services allows operators the flexibility to optimize how they will deliver 10G to homes and businesses.

Earlier this year, the NCTA partnered with the Future Today Institute to explore how 10G will transform our lives. Through research and the release of white papers, the two organizations brought to light the potentially transformative impact of 10G across four key critical industries: agriculture, health care, education and entertainment.

The 10G Challenge

Developed and executed by CableLabs from inception to completion on behalf of the industry, the 10G Challenge encouraged innovators to ponder transformative solutions that leverage the speed, security, reliability and low latency of the 10G network. This first-of-its-kind technology challenge was designed to accelerate the development of applications for emerging 10G networks. Innovators across the United States and Canada developed and submitted entries outlining solutions that will shape the ways we live, work, learn and play in the future. The six winners rose to the challenge, devising life-changing technologies that highlight the incredible capability of 10G.

The 5G Challenge

As the host lab for the 5G Challenge, CableLabs contributed the standalone 5G network on the 10G lab platform, as well as its expertise with open and interoperable network technologies. The 5G Challenge was presented by the NTIA’s Institute for Telecommunication Sciences in collaboration with the Department of Defense with an aim of accelerating the development and widespread deployment of open and interoperable 5G networks with true plug-and-play operation.

CableLabs’ Technological Advancement

Convergence Confirmed

At SCTE Cable-Tec Expo 2022, CableLabs leveraged the critical capabilities of the 10G Lab to test several network-as-a-platform concepts, and to successfully demonstrate how to improve scalability and reliability with the power of a converged network running on virtualized infrastructure.

As broadband traffic continues to surge, cable operators must upgrade networks to expand capacity and boost efficiency. Enter convergence. This broad converged platform can support multiple network software stacks using a common management interface. The goal? Enabling operators to mix and match wireline and wireless services over the same core infrastructure. The realization of full wireline-wireless network convergence ultimately improves scalability and reliability and serves as a foundational element on the road to 10G.

Successful Interoperability

Low Latency, Low Loss, Scalable Throughput (L4S) technology is a critical component of Low Latency DOCSIS. By exhibiting dramatic improvements in latency when using L4S at an interoperability event, CableLabs and its subsidiary, Kyrio—with support from Comcast, Apple and Google—demonstrated how L4S will enable the media interactivity and immersion necessary to unlock the metaverse. With L4S providing precise feedback to applications about impending congestion, the technology can help advance the speed, low latency and reliability of the multigigabit platform of the future.

Validating Point-to-Point Coherent Optics (P2PCO)

To support higher-capacity infrastructure—thereby supporting the speed, low latency and reliability necessary to deliver 10G—CableLabs’ Point-to-Point Coherent Optics (P2PCO) technology creates a network connection between two points that use coherent optical transceivers.

By using one laser for bidirectional, single-fiber transmission, P2PCO doubles the fiber’s capacity and takes existing access network fiber to the insanely fast speeds needed for 10G, meeting growing broadband consumer demand. In July, CableLabs confirmed that devices compliant with its P2PCO PHYv2.0 specification can transmit over roughly the same distance as devices compliant with the PHYv1.0 spec—and at double the operating capacity: 200 gigabits per second versus 100 Gbps per wavelength.

Standards and Specifications

This year, CableLabs and SCTE—a CableLabs subsidiary—submitted several specifications published as standards, including the Generic Access Platform (GAP) specification and standards for 1.8GHz actives to DOCSIS 4.0 technology. These standards and specs help provide operators with all the necessary technologies or tools to get to 10G.

Between convergence, L4S, P2PCO and emerging industry standards and specifications, CableLabs-driven technological advances are foundational in supporting most of the key tenets of 10G.

At CableLabs, we understand the vital need for network connectivity to power whatever our increasingly data-driven world demands next. That’s why we foster collaboration between members and technologists to move society closer to 10G speeds, lower latencies, enhanced network reliability and better security daily.

Up Ahead: Better Connections, Happier Users and Lower Costs

Whether at home, in the office, at a coffee shop or on the go, we all expect a dependable internet connection. Even when we're offered bundled services that combine wireless and wireline network access, uninterrupted connectivity often isn't as straightforward as it sounds. Simply providing connectivity over multiple access network types isn't sufficient for meeting customers’ expectations, and managing these as independent networks drives operational costs and complexity.

Wireless-wireline convergence (WWC) solves these problems for consumers and operators. WWC—or fixed-mobile convergence, as it’s sometimes called—enables ubiquitous connectivity that works seamlessly, meeting customers’ needs and simplifying network operations.

CableLabs is working with member and vendor communities to make this a reality. We’ve recently published a white paper that lays out the roadmap to WWC.

How Wireless-Wireline Convergence Works

The WWC architecture simplifies networks by eliminating redundant capabilities that exist across wireline and wireless access networks and enabling seamless operations across access technologies. These redundancies, which include subscriber databases, routing function and security capabilities, are converged under the WWC architecture.

At the heart of the WWC architecture is a single converged core based on the 3GPP 5G mobile core. The mobile core was selected as the foundation for the converged core over wireline cores since mobile cores support devices moving across access networks.

Wireline-Wireless Convergence Architecture

Under the WWC architecture, a single converged core will enable seamless wireless access across Wi-Fi and cellular networks.

When Will Network Convergence Become a Reality?

We’d all like to snap our fingers and begin reaping the benefits of a fully converged network tomorrow. However, because of a substantial installed base, as well as gaps in current products, standards and specifications, this is going to be a journey. Fortunately, the foundation for WWC is already being delivered with help from current technologies.

CableLabs’ member and vendor collaboration will help resolve the gaps in converging DOCSIS® networks, passive optical networking (PON) and Wi-Fi with mobile networks. Existing CableLabs and other industry specifications will be updated and extended, and new specs will be developed.

We’ve mapped out the WWC roadmap into three general phases—starting by connecting what is deployed today and progressing towards fully converged networks.

Wireline-Wireless Convergence Deployment Roadmap

The roadmap evolves toward a complete integration of wireline and wireless networks, beginning within the decade.
