How Does WiFi Work on Airplanes?
SpaceX has plans to use its low-Earth orbit Starlink satellites to offer in-flight WiFi for "several" airlines. Most airlines do already offer in-flight WiFi, usually for a fee, but it's more primitive. There's no timeline for the Starlink airline project yet, but when it does go live, it will significantly expand Starlink's terrestrial WiFi coverage. Elon Muskvia Starlink, a division of SpaceXis in talks with "several" airlines to provide in-flight WiFi for passengers. His plan is to use Starlink's ever-growing megaconstellation of satellites to equip customers with better WiFi while they fly the friendly skies.  You love cutting-edge tech. So do we. Lets explore it together. Jonathan Hofeller, SpaceX's vice president of Starlink and commercial sales, gave out details on the ambitious plan during a panel at the Connected Aviation Intelligence Summit on Wednesday. "We're in talks with several of the airlines," Hofeller said during that panel, according to The Verge. "[W]e've already done some demonstrations to date, and looking to get that product finalized to be put on aircraft in the very near future."

One of the current industry leaders, Hughes, employs a small number of satellites to provide internet access to about 25 million people. Its internet offerings could soon pale in comparison to Starlink's; SpaceX has already launched about 1,800 of the 4,400 satellites it needs to deploy its high-speed connection. Well, in Starlink's case, SpaceX has used rockets to launch dozens of satellites at a time into low-Earth orbit (within a 1,200-mile altitude). Folks who have signed up for Starlink's public beta program each have a special Starlink satellite dish that can align itself with the 1,800 satellites orbiting Earth. Starlink notes on its sales website that it's normal for beta users to experience signal blackouts, which illustrates just how nascent the program is. Still, tens of thousands of users have signed up. It's a smart way to soft-launch a product, while still soliciting tons of critical user feedback as development continues. It's both harder and easier to make happen, depending on your criteria. Hofeller said that SpaceX will design and fabricate new antennas for the airline industry, similar to the ones Starlink already uses for ground internet service, but "with obvious enhancements for aviation connectivity." These antennas, outfitted on planes, will communicate with ground stations that link up with Starlink satellites. That's great for a flight from Pittsburgh to Los Angeles, but cause for concern if you're boarding a transatlantic flightafter all, there aren't exactly satellite base stations installed in the middle of the ocean. So, Starlink satellites will have to communicate with one another, rather than rely on a connection with ground stations. Today's in-flight WiFi faces similar issues. There are two primary options that airliners use to provide internet to customers, both of which begin on the ground. First is "air-to-ground WiFi," which uses cellphone towers to nab a signal, similarly to how your smartphone pings 4G or 5G base stations. Just think of the airplane like a giant smartphone operating as a hotspot. This content is imported from YouTube.

The second option for airplanes is satellite internet, wherein a signal beams from the ground and bounces from a satellite to the airplane, in the same way that Starlink and Hughes provide WiFi to home users. By using a high number of satellites, and installing interconnectivity functionality between those satellites, Starlink will change the game for transatlantic flights, where coverage has traditionally been spotty or slow due to the distance the signal must travel. Unfortunately, we have no timeline for when Starlink's new airline coverage will go online. To be determined. Don't know. Hopefully sooner rather than later," Hofeller said. Meanwhile, rival satellite internet company OneWeb was happy to announce its timeline for in-flight WiFi, which is sometime in the middle of 2022. But then again, Elon Musk has always operated on his own schedule.
