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.
While most planned satellite constellations used for connectivity fly in low earth orbit (LEO), some fly in geosynchronous equatorial orbit (GEO) and circle the earth from a much further distance.
Because of this distance, LEO satellites tend to have lower latency and higher bandwidth than their GEO counterparts.
So when MetTel tried to cross its SD-WAN offering with HughesNet's GEO connection, it got latency.
More on this story and our other January telecom reading recs below.
The international voice market's trajectory is down, and there's no reason to believe it's coming back.
Our recently updated TeleGeography Report and Database shows us exactly how fast traffic volumes are plummeting.
This week on TeleGeography Explains the Internet we welcome Jeremiah Ginn, Software Defined Cybersecurity Evangelist at AT&T and author of Diving into SASE.
Back in 2018, the Panamanian government rubber-stamped long-gestating plans to reduce the mobile market from four players to three, seeking to make better use of the country’s spectrum resources.
Despite multiple meetings, no breakthroughs were achieved, and all four operators were unwilling to concede ground.
Five years later, multiple international telecom groups have exited Panama and the authorities find themselves in the unusual position of trying to attract a new operator to fill the void.
Today, we track the key events that led to this point.
This week's guest on TeleGeography Explains the Internet has a deep history in networking.
Khalid Raza was involved in some of the earliest large-scale MPLS deployments. Then, after seeing the limitations of MPLS, he co-founded Viptela–diving head-first into the SD-WAN revolution.
Khalid is now the Founder and CEO of Graphiant, a Silicon Valley-based startup. In this interview, he describes how enterprise networks have changed and why we need an approach beyond MPLS and SD-WAN.
If you've been involved in the WAN/IT infrastructure space for the past few years, you've probably heard about SASE, or Secure Access Service Edge.
The enterprise market is just beginning to integrate this new technology into network security strategy and many professionals are still broadly unfamiliar with it. As a result, it's common for WAN speakers and writers to repeatedly clarify what SASE is (and speculate on whether vendors are “SASE washing”).
In fact, our 2021 WAN Manager Survey found that only one-third of enterprises had adopted either SASE or Zero Trust. And one in ten respondents had never even heard of SASE.
U.K.-based Vodafone Group has agreed to leave the Hungarian telecom market after more than 20 years of competing in the country’s mobile and fixed sectors.
Our first new map of 2023 is here! Meet the brand new Africa Telecommunications Map.
This edition depicts 72 cable systems connected to Africa that are currently active or under construction.
The TG team is enjoying OpenAI's new ChatGPT—an artificial intelligence assistant trained to answer questions and provide information on a wide range of topics—and our Slack channels show it.
As usual, we can't help talking about telecom, so our analysts have made a game of testing ChatGPT's submarine cable knowledge.
How well has it fared?
