We usually think about wireline and wireless as alternative, complementary and at times competing ways to provide connectivity. But increasingly connectivity to any device requires the combination of wireline and wireless components. Access is mostly wireless through cellular, Wi-Fi, Bluetooth or other interfaces, and, eventually, the connection is transported to fiber. What is variable is where the wireless signal moves into the wireline realm. For instance, backhaul can be wireless or wireline.
Does it still make sense to think of wireless and wireline as separate? Or are they both inherently necessary components of connectivity? I debated these questions with Mark Gilmour at ConnectiviTree. He has been the wireless guy when working with wireline companies, and the wireline guy when working for mobile operators or vendors, so he has a uniquely deep and multi-sided perspective on the wireless/wireline contraposition.

Geoff Hollingworth, CMO at Rakuten Symphony, and I agree on many things, but we have sharply different views on the success of 5G. I think 5G did just fine; Geoff thinks it was a failure. So we set to debate this, and we had quite a revealing conversation (I don’t want to spoil it) on technology, standardization, 3GPP, monetization and, of all things, communism.

We often may feel that much of technology innovation in wireless either does not get deployed in commercial networks or that the process is very slow. Is that the case? And what sets the pace of innovation? Are there areas where we should be innovating at a faster rate to meet our connectivity needs, especially those of enterprises and other verticals?
Sumit Roy, a professor at the University of Washington in Seattle, shared his perspective gained in work in the private sector, government and academia.

This is the second part of the discussion I had with Preston Marshall, Director of Wireless Standards and Policy at Google Internet Evangelism, Co-Chair of Spectrum Sharing Committee at WInnForum, and Chairman, OnGo (CBRS) Alliance.
At the end of the first episode, we realized we did not cover many of the topics we had on our list, so we recorded a second episode. We still did not cover all of them, but we made some progress. In this episode, we talked about 3GPP, spectrum, private networks, CBRS, phone numbers and SIM cards.
Again, our discussion took inspiration from Pres’ new book, Evolving to 6G: The Case for a New Approach to 6G and Beyond, an excellent analysis of what we have achieved so far in wireless, what we still need, and what we want 6G to do.

Everybody pursues monetization, yet it appears to be increasingly elusive. Just as love can be. Yet, I argue that finding love in life is easier than finding monetization in wireless.
Not everything is lost, as long as we think of monetization not primarily in terms of new or larger revenue streams but in terms of profitability—which takes us to selective adoption of technology to increase efficiency rather than get a few dollars from unwilling subscribers.
It may help to think of direct and indirect monetization and how they both address the opportunity for additional revenue and increased efficiency, and the risks that each entails. We may revise the largely held view that 5G has been a failure and the fear that 6G may be a repeat of that experience.

We still do not know what 6G is going to be, but it is the right time to decide what we want it to do. I talked to Preston Marshall, Director of Wireless Standards and Policy at Google Internet Evangelism, CoChair of Spectrum Sharing Committee at WInnForum, and Chairman, OnGo (CBRS) Alliance, about what users, the operators and the rest of the wireless ecosystem need 6G to do differently, and not just better, than 5G.
Pres and I talked about how to think about monetization in 5G and 6G, the crucial role of the core in the evolution of wireless connectivity, the roles of Wi-Fi and cellular in providing connectivity for different use cases, private networks run by the enterprise, and Wi-Fi and cellular coexistence.
Throughout the discussion, we refer to Pres’ new book, Evolving to 6G: The Case for a New Approach to 6G and Beyond, which I highly recommend not only for its vision for 6G, but also for the insightful and frank assessment of past and present of cellular and Wi-Fi connectivity.
A second episode with Pres covering other topics from his book will be soon available.

Magnus Olden, CTO at Domos, comes to telco API from an IT and Wi-Fi background and works to make API less complex, more easily usable and valuable to application developers.
We talked about what app developers need, and how their perspective can be very different from that of operators and the telco ecosystem. How could we get telcos and app developers to both benefit from API? How can we get APIs to also cover Wi-Fi access? What are the implications for API adoption and monetization? We squeezed a lot in our half-hour conversation.
I highly recommend the meeting that Magnus organized recently (and that convinced me to write my upcoming report on network APIs)

John Baker is the SVP of Business Development at Mavenir and one of the strongest proponents of Open RAN, since the very beginnings. We have talked about Open RAN in a previous Sparring Partners, and this is an update on the progress of Open RAN and the market outlook.
How are we moving from Open RAN to end-to-end open networks? How is the concept of Open RAN evolving? Open RAN deployments are taking longer than some initially expected: Does it mean that Open RAN is not working as expected, or that it simply takes time to get all the parts working together? How effective are open interfaces in opening the network to a more complex, larger ecosystem? How useful are market forecasts for Open RAN? How should we define Open RAN in a market forecast (or in other contexts)?
You can get the latest version of the O-RAN ecosystem slide from John Baker's LinkedIn posts

A conversation with Markus Kümmerle, Deutsche Telekom and CAMARA, Daryl Schoolar at Recon Analytics and Monica Paolini at Senza Fili on the value, benefits and challenges of APIs
APIs have been around for a long time, but in the last couple of years have become one of the brightest beacons of monetization, even though their role is much wider than that. With the GSMA launch of the Open Gateway, there are signs of growth and adoption, but also questions about adoption paths, use cases and business models.
In this Sparring Partners, Markus Kümmerle, Deutsche Telekom and CAMARA, Daryl Schoolar at Recon Analytics and Monica Paolini at Senza Fili dissected the opportunities and challenges of APIs and look into what’s ahead for operators, application developers, hyperscalers, and everybody else in the ecosystem.
Use cases: What are APIs good for?API definition: What’s the role of open, internal, operator-specific and vendor-specific APIs?Monetization: Will APIs be better at improving network efficiency or at generating new revenues?Business models: Who will pay for APIs? What services need APIs?You can watch the video of the Sparring Partners at https://senzafili.com/videos/sparring-partners-apis-the-good-the-bad-the-debatable/

In network operations, we are always looking for areas for improvement. How should we manage applications to best serve end customers? How can we use end-to-end visibility of application and service performance to end customers, anomaly detection for automated pattern discovery and prediction to improve quality of experience? How should we utilize software-driven networks to deliver new services and support monetization strategies?
In this Sparring Partners with Rick Fulwiler, Chief Solutions Architect at NETSCOUT, we discussed how AIOps is becoming the focal point driving the transformation to improve network operations across all lines of business—IT, enterprise, cable, security and wireless. However, all these efforts will fail without being able to feed rich and reliable network data to AIOps.

Most of the time, we talk about how AI, ML and GenAI change the way we run and operate networks, enable automation, tame complexity, and improve efficiency. They also change the way we – the humans in telecoms – operate, the skills we need, and how we deal with AI-based platforms. This will require profound changes and our ability to meet the cultural and technological challenges is going to be crucial to benefit from AI.
In this Sparring Partners, we talked with Azita Arvani, formerly at Rakuten Symphony, and Paul Patras at Net AI and the University of Edinburgh about how AI, ML and GenAI will change our networks and the people working with them – vendors, service providers, researchers, analysts and everybody else.
Are we ready for the challenge? How can we prepare for it? How do organizations need to change? Can we attract the talent we need in telecom?

It is not coincidental that networks are evolving towards openness and automation at the same time. Openness brings flexibility and choice, but also increased complexity. Automation, aided by cloudification and AI, enables operators to manage complexity and benefit from the flexibility in the network. Together, openness and automation change the way we operate networks and deliver services.
In this Sparring Partners with Brandon Larson, SVP, GM, Cloud, AI & IMS at Mavenir, we talked about how openness and automation work together to
