Questions & Answers

Q: How does the internet travel across the ocean?

Internet traffic across the ocean is facilitated by submarine cables, which are laid down by specialized vessels and connected to internet hubs in various countries.

Q: What happens if an anchor cuts an underwater cable?

Damage to underwater cables can disrupt internet connectivity, as seen in the case of Tonga, where an anchor cut caused a 13-day internet outage.

Q: How does 5G technology make the internet faster?

5G uses higher frequency waves, allowing for more data to be transmitted. However, it requires more physical infrastructure and may not benefit those in rural or low-income areas.

Q: How does Loon's balloon internet work?

Loon sends balloons into the stratosphere to provide internet access to areas with limited connectivity. The balloons use radio waves and communicate with ground stations and other balloons to establish connections.
