Wanna look at some cool voice data? The recent expansion of the i3forum's Insights tool has quite a bit of that. I've been itching to talk about it on TeleGeography Explains the Internet. So today we're chatting with the i3forum, a nonprofit industry body focused on "accelerating transformation across the carrier ecosystem." Put another way: this consortium of carriers routinely collaborates on solving some of the biggest challenges facing their industry. And they have a really innovative...

You'll hear Aaron's view of the long-term profitability of network operators and what he looks for in making investment decisions in the telecom space. We...


418: Behind the Seas—Making Our Famous Submarine Cable Map

There's a good chance that you first heard about TeleGeography through one of our maps. Our own Research Analyst Lane Burdette was introduced to TeleGeography when she came across our Submarine Cable Map a few years ago. Now part of the team that creates this map, Lane is understandably stoked about this week's 2023 Submarine Cable Map launch. It seems like the perfect time to welcome Lane—along with our incredibly talented Designer and Cartographer Larry Lairson—to TeleGeography Explains...

We talk about the history of telecom and how voice and internet networks compare—and how that is impacting voice traffic and revenue. The conversation also covers the cash cow that voice once was and what's happening now. Voice enthusiasts will...


415: Unpacking Telecom Predictions of the Past

It's one thing to make predictions. It's another to go back and assess how those predictions shook out. One month into 2023, Mattias Fridström, Chief Evangelist at Arelion, very kindly agreed to scrutinize his 2022 forecast with us. As you will hear, Mattias has been at Arelion (formerly Telia) for a long time. From his perspective within a tier 1 provider, he has an outstanding view of the industry. He uses that vantage point to write a forward-looking article every year, reviewing trends...

In this interview, he describes how enterprise networks have changed and why we need an approach beyond MPLS and SD-WAN. We also...

When we reached out to today's podcast guest—Jim Poole, Vice President of Business Development at Equinix—about being on the show, we asked if he'd be willing to dig into NaaS or edge data centers.
