614: An FCC Commissioner Explains Spectrum Allocation and Broadband Expansion

Joining us today is FCC Commissioner Nathan Simington.

Commissioner Simington has served on the Commission since late 2020. He brings a diverse background to the role, including experience with the NTIA.

The Commissioner and Host Greg Bryan cover several key issues facing the FCC:

👉 Several issues surrounding spectrum allocation and use. We talk about how FWA and LEO fit in spectrum plans, CBRS, unlicensed spectrum, and, of course, a bit on spectrum auctions.

👉 BIL and broadband development and the role wireless can play in closing the digital divide.

👉 The FCC’s role in submarine cable development and the Commissioner's views on ensuring submarine cable security.

👉 The Cyber Trust Mark and the FCC’s role in securing the ever-expanding threat perimeter and the Commissioner's views on how to get OEMs invested in keeping users safe.

612: Lightyear Considers the State of Connectivity

Dennis Thankachan, Co-Founder and CEO of Lightyear (https://lightyear.ai/), is back on the pod.

We discuss Lightyear's State of Connectivity Report (https://lightyear.ai/ebooks/lightyears-state-of-connectivity-2025), which dovetails with the topics we research here at TeleGeography. It may be a perfect companion to our State of the Network effort. (https://www2.telegeography.com/download-state-of-the-network)

609: A Telecom Year in Review

As the year ends, a few teammates joined us on the podcast to review the major telecom events of the past 12 months and chat about what we might anticipate in 2025. Some highlights 👇

⛓️‍💥 Analyst Lane Burdette joins the show to review some of the most headline-grabbing trends (https://blog.telegeography.com/what-to-know-about-submarine-cable-breaks) we saw in the submarine cable world.

☁️ While cables keep the continents connected, Principal Analyst Patrick Christian got on the mic to discuss one of the key reasons for that connectivity demand: cloud services.

📈 Of course, data centers underpin the cloud. For that conversation, we welcomed back Senior Manager Jon Hjembo after explaining our new Market Connectivity Score a few weeks ago (https://blog.telegeography.com/a-guide-to-calculating-the-worlds-next-interconnectivity-hub-according-to-you).

🐝 When it came to enterprise networks in 2024, it was hard to have a conversation that didn’t involve NaaS and security (https://blog.telegeography.com/when-networking-and-security-collide), specifically SASE. To talk about the trends surrounding the buzzwords, we had to call on Research Manager Brianna Boudreau.

🌎 So many of these conversations are underpinned by the transport network. To chat about the cost of sending bits around that global network, we were thrilled to welcome Research Director Rob Schult to tell us what was noteworthy in the world of telecom pricing in 2024.

607: Internet Sourcing, as Explained by an Internet Aggregator

Our guest today is Rutger Bevaart, CEO and Co-founder of GNX. Rutger has a deep history in the telecom industry and founded GNX to streamline internet sourcing, which is undoubtedly a pain point for many listeners.

We discuss the shift away from MPLS and toward the internet and how that transition can bring many benefits to an enterprise; however, it also comes with complexity and new challenges, especially in sourcing and managing internet links worldwide.

605: A Guide to Calculating the World's Next Interconnectivity Hub (According to You)

Where are we building data centers? Why? What markets are primed for interconnectivity glory? Which ones are getting left in the dust?

We've heard these questions repeatedly, so we did what any reasonable telecom data provider would do: we developed an interactive tool to rank the world's best-connected and fastest-growing cities, scoring them on a scale of 0 to 100 across nine key categories.

This week's guest is resident data center expert Jon Hjembo. He explains how we developed the Market Connectivity Score and reveals what initial rankings tell us about the interconnectivity landscape and metro areas to watch, like Kuala Lumpur.
