Growing pains in telecoms. With Joel Brand, Marvell

Telecoms has become a mature industry after decades of explosive growth. How do we manage innovation, the introduction of new technologies, and the growth expectations in this new environment?
I talked with Joel Brand, at AVP Product Management at Marvell, about how we can adjust to the new environment and what changes we need to make. Telecoms has been and still is an astounding success, even though we often complain about not meeting our expectations. We spanned many topics, including dumb pipes, utilities, replacement rates, power efficiency and sustainability, network capacity and efficiency, 5G, learning from other sectors, the Lego model, AI (and hype) and AI-RAN.

Better indoor Wi-Fi connectivity with Passpoint and Wi-DAS. With Howard Buzick, American Bandwidth

Most indoor connectivity already goes through Wi-Fi. Why do we need Passpoint to improve access to Wi-Fi networks? How can a Wi-DAS deployment help? Howard Buzick, Co-Founder at American Bandwidth, told us how Passpoint makes our Wi-Fi connections more seamless and secure and how American Bandwidth helps retail, healthcare, education and government organizations use Passpoint and a Wi-DAS architecture to make it easier to connect to their networks and to improve coverage.

Wireless ticketing on trains in the US: Why is it so hard? With Jim Allison, CCJPA

If you use public transportation across countries, you probably noticed how much easier it is to pay with your phone in Europe or Asia than in the US. In part, this may be due to the more limited public transportation infrastructure and use and lower use of contactless payments for non-cash payments (half that of Europe).
But what I learned from talking to Jim Allison, Manager of Planning, Capitol Corridor Joint Power Authority (CCJPA), is that setting up wireless ticketing in the US is extremely complex – more so that, say, in the UK. Jim managed to pull it off and tells us how he did it. It is a fascinating story about how regulation and ecosystem structure exert a power that no amount of technology can match.
I have worked with Jim for a very long time to get Wi-Fi on CCJPA and Amtrak, and we talked about that too. We now take free Wi-Fi on trains almost for granted, but it took some time and effort to get there.

Real-life, revenue-generating network APIs at TIM Brazil. With Leonardo Siqueira, TIM Brazil

Commercial adoption of APIs is still in the early days in most markets, but there are a few exceptions. Brazil is one of them, with operators offering them to app developers and getting revenues from them, supported by market demand and a facilitating regulatory environment. I talked with Leonardo Siqueira, Data Monetization and Mobile Ads Director at TIM Brazil, about the API rollout from 2023, the use cases, business models and what lies ahead.

Open DAS: Open RAN and DAS converge. With Upendra Pingle, ANDREW

It is hard to overstate the need for more indoor capacity and better coverage when you think that over 80% of traffic comes from indoor locations. And to address this need, we need more indoor infrastructure. But what’s the best way to get there? DAS or small cells? Or is Wi-Fi enough?
I talked to Upendra Pingle, General Manager, Indoor Cellular Networks at ANDREW, an Ampehnol company, one of the most passionate advocates of indoor coverage, and we talked about what could be a third way: Open DAS. It is different from the expensive and complex traditional DAS, and closer to a small-cell open-RAN architecture. How should we think about the Open DAS? How can DAS benefit from disaggregation? And are we at a point where DAS and small cells converge into a hybrid model?

Attracting talent in telecom. With Simona Marinova, Bell Canada

Telecom is no longer the magnet for talent that it was when I joined. Talented people entering the job market now often prefer to work for hyperscalers or other high-tech companies. Why is it so? And how can we make telecom more attractive to the younger generations?
I talked to one of the super-talented young people, Simona Marinova, Solution Architect at Bell Canada, who bucked the trend and joined Bell Canada while doing her Ph.D. at the University of Toronto to see what motivated her to get into telecom and to talk about what we can do as an industry to attract her peers.

Blockchain enables new offload and sharing models. With Mario Di Dio, Nova Labs

Offload can improve subscriber experience and reduce operators’ costs, but it is still limited because we do not have the right economic incentives and transparency on the quality of the offload. Can blockchain help create new business models that combine transparency and incentives and that will get offload off the ground? Mario Di Dio, GM of Network at Nova Labs/Helium, presents a new offload model that uses blockchain to share KPIs and the real-estate value of Wi-Fi offload connections and to create a market for Wi-Fi hotspot owners and operators to manage offload.

5G lessons learned. With Azita Arvani

We are midway in our 5G journey. It may not have been as game-changing as many expected, but it did improve connectivity, and it is an impressive new technology. There is ample room for improvement, this much is clear.
What can we learn from the beginnings of 5G to continue the innovation? What should we do differently? Azita Arvani, ex-CEO at Rakuten Symphony North America, and I agree that we should not give up on 5G and wait until 6G arrives. But how aggressive should we be in pushing technological innovation in an affordable way?

Wireless/Wireline: Is the contraposition still relevant? With Mark Gilmour, ConnectiviTree

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.

QuickFire | Was 5G a failure? With Geoff Hollingworth at Rakuten Symphony

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.

QuickFire | Why does it take so long to innovate? With Sumit Roy, University of Washington

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.

QuickFire | What should 6G do for us? Part 2 With Preston Marshall, Google

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.

QuickFire | Why monetization is harder to find than love

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.

QuickFire | What should 6G do for us? With Preston Marshall, Google

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.

QuickFire | The software developer view on telco APIs, with Magnus Olden, Domos

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)
