Behind the 'Internet of Things' Is Android—and It's Everywhere

Ken Oyadomari’s work space at NASA Ames Research Center in Mountain View, Calif., looks like a triage tent for smartphones. Parts from dozens of disassembled devices are strewn on workbenches. A small team of young engineers picks through the electronic carnage, carefully extracting playing card-size motherboards—the microprocessing heart of most computers—that will be repurposed as the brains of spacecraft no bigger than a softball. Satellites usually cost millions of dollars to build and launch. The price of Oyadomari’s nanosats, as they’ve become known, is around $15,000 and dropping. He expects them to be affordable for high school science classes, individual hobbyists, or anyone who wants to perform science experiments in space.

A big reason nanosats are so small and cheap: They run on Google’s Android operating system, familiar to anyone who’s shopped for a smartphone or tablet. It’s the No. 1 mobile OS by a wide margin; Android handsets outsell Apple’s iPhones globally by about 4 to 1. Impressive as those numbers are, they actually understate Android’s prevalence, because increasingly it’s the operating system behind just about anything with a computer chip. Along with Oyadomari’s nanosats, three of which recently went into orbit, Android runs espresso makers, video game consoles, refrigerators, rifles that post video to Facebook, and robotic harvesters for farms.

Android is becoming the standard operating system for the “Internet of things”—Silicon Valley’s voguish term for the expanding interconnectedness of smart devices, ranging from sensors in your shoe to jet engine monitors. As each of these devices hits the market, Google further outflanks Apple and Microsoft as the dominant software player in a connected world.

Android’s risen so fast in part because Google gives away the software to device makers and developers. Google is counting on making money from ads and other services on Android phones and tablets. The software is also open-source: Anyone can tinker with the code and use it in any gadget they want. The NASA engineers fine-tuned the operating system to require less power, letting their tiny satellites run for days on a handful of batteries. “If we can have satellites that are really small and really cheap, it will be interesting to see what some guy in his garage will be able to do with them,” says Oyadomari.  (...)

Google isn’t the only tech company to introduce its own minimalist, Linux-based operating system. Years ago, Intel developed a version of Linux for mobile called Moblin, while Nokia built another version called Maemo. Palm’s WebOS also had Linux at its core. As usually happens with operating systems, such as Microsoft Windows on PCs in the 1990s, tech companies coalesced around one product. For just about everything that isn’t a server or a PC, the winner is Android.

Jim Zemlin, executive director of the nonprofit Linux Foundation, says Android has conquered the device market from the bottom up. The operating system ran on 75 percent of the smartphones—162 million units—shipped during the first quarter of this year, according to the research firm IDC. While iPhones and iPads come in very few versions and only from Apple, Android-powered mobile hardware of all shapes and sizes and brands has flooded the marketplace. The companies that build components have had to scramble to make sure everything they make functions well with all those gadgets. The result is a huge and growing number of hardware makers and software companies becoming expert in all things Android. “Every screen variant, mobile chip, and sensor known to man has been tuned to work with Android,” Zemlin says. “There’s this network effect, so that now anyone who wants to make a custom product can take Android and morph it into anything.”
