In honor of the upcoming fifth season of TeleGeography Explains the Internet, we’re running you through the highlights of all 25 episodes from Season 4, five at a time.
Revisit part one to watch clips on energy conservation in the fiber optic space, the resurgence of satellite, the changing nature of technology, and more.
“Submarine cables account for over 99% of intercontinental data traffic” is regularly quoted in the press with no source given.
It’s time for some fact-checking.
We just wrapped up the fourth season of our podcast, TeleGeography Explains the Internet.
After three seasons focused primarily on the WAN, Senior Manager/Podcast Host Greg Bryan spent the last few months more broadly exploring the global business of connectivity with a wide range of guests.
A lot of ground was covered. In fact, if you were to binge the whole season at once, it would take around 20 hours to listen through all 25 episodes.
While that would be very impressive, we've made a highlight reel with bite-sized clips to help you catch up. Stay tuned as we work our way through the season, five episodes at a time.
How are submarine cables impacted by tectonic shifts beneath the seafloor?
This week's guests on TeleGeography Explains the Internet are well-positioned to tell us. They join us from the UK’s National Oceanography Centre: Isobel Yeo, Researcher in Geology and Volcanology, and Michael Clare, Principal Researcher of Ocean BioGeoscience and Marine Environmental Adviser to the International Cable Protection Committee.
Mike and Izzy are geologists specializing in the seafloor, so their research has become vital for the submarine cable community.
It's regularly cited in the press that $10 trillion of financial transactions flow over submarine cables every day. But is it true?
With a fresh map release, an updated e-book, a new presentation deck and more, March has been madness for TeleGeography.
Let's recap some stuff you might have missed.
On TeleGeography Explains the Internet, I typically interview guests who work in the telecom industry or manage telecoms at large enterprises.
Not this week!
Meet Aaron Chan, Founder and Managing Partner at Recurve Capital. As an investor in the “technology media and telecom” space—or “TMT” as they say in finance circles—Aaron has something of an outside perspective.
We're closing out February with our top five telecom reading recommendations from the month.
First up: a look at how submarine cables are vulnerable to sea-level rise, storms, and other climate impacts.
