Drones, and Loons, and Satellites! Oh, My!

In an age of constant connectivity and technological advancement, there remain many people who are still unable to access the Internet and all it has to offer. Not to worry though because companies like Google, SpaceX, and Facebook have some very innovative designs that hold great potential for providing reliable high speed Internet to the world. 
Google’s groundbreaking plan, which would be comical if they weren't successful, involves balloons. Google wants to use balloons that float around 12 miles up in the stratosphere. Project Loon is designed to have a communication network composed entirely of solar powered balloons, all of which can communicate with each other and pass data along from one balloon to another until the data reaches a balloon that is within range of a desired ground receiver. By using LTE, Loons are able to connect with mobile phones as well as base stations that have a special antenna. Incredibly and despite some balloon experts expectations (who knew there are balloon experts?), Google eventually was able to engineer balloons that can remain afloat for at least 100 days! Google was able to accomplish this feat because, “Loon engineers concluded that one of the biggest factors in failure were small, almost undetectable leaks in the polymer skins that must withstand huge atmospheric pressure and up to 100 mph winds. Even a pinhole can shorten a balloon’s lifespan to a few days.”
I really like the above illustration. It is fascinating to follow the flight path of Ibis 152, a balloon that flew for over 100 days. Isn’t it incredible how a balloon can circle Antarctica several times? Another balloon named Ibis 162 circled the globe three times and broke a world record by completing one circumnavigation in 22 days.
SpaceX, on the other hand, promises to deliver Internet to the world by launching a massive satellite network into low-Earth orbit at approximately 750 miles up. Elon Musk, CEO of SpaceX, is planning a network that is very similar to that of Google’s Project Loon but instead of using balloons to deliver Internet, Musk wants to launch hundreds or even thousands of satellites into orbit. Musk certainly has an advantage in this game since he has SpaceX at his disposal for all the satellite launches; however, satellites are not as easily fixed or updated. Unlike Project Loon or Facebook’s Internet drones, satellites cannot be maintained as easily. Both Google’s Loons and Facebook’s drones can land which allow hardware and software to be more easily maintained and upgraded on regular occurrences. This is why Musk is investigating using optical lasers for communication between satellites instead of radio spectrum. Musk is claiming that a network built upon satellite communication will be faster than a fiber optic caber because electromagnetic waves move faster in the vacuum of space.
It is hard to decide which project I find more thrilling: Facebook’s drones, Google’s Loons, or SpaceX’s satellites. All the companies are competing in different and exciting ways to reel in the next Internet market and thus become their Internet providers. Honestly, I’m not so fond of Facebook Internet drones and the same goes for Amazon’s proposed drone delivery service. Drone projects pose some pretty serious security and safety issues that require a great deal of thought and work. Developing countries will not be the only ones who will benefit if one of these technologies becomes a reality. Projects like Loon can fill in the gaps in service in rural areas or even cities where cell towers sometimes cannot reach or fail to connect due to hills, skyscrapers, or other types of interference. So the next time you see a balloon in the air, check your phone because you may be connected to Google’s Wi-Fi.

  1. While Loon and Faceboook's drones do seem easier to service, they seem like a band-aid solution to the problem of haven an established internet infrastructure in third-world countries and rural areas. In Elon Musk's solution, we would have a strong, long-lasting infrastructure that requires little maintenance. Satellites orbit the Earth in the vacuum of space, free from any atmospheric turbulence, and their lifespan are much greater than that of a weather baloon or equivalent (Loon). In my opinion, I would have to say that SpaceX's solution is the better one here.

  2. I'm happy for all of these projects because they prove that we are trying to provide these utilities to Third World Countries, in places that would be next to impossible to provide your typical broadband or even cellular service. I agree that the SpaceX solution seems the most concrete and long-lasting, but all of these are, at a minimum, a fantastic effort.
