A new mobile messaging application called FireChat is empowering nearby smartphone users to stay in touch even when there's no cellular service or Internet connection.
In just two weeks since its release on the iPhone, FireChat already has provided a flicker of hope for people pining for more effective, secure and affordable ways to communicate. That's because the free messaging app harnesses a technology called wireless mesh networking, which might someday allow a myriad of devices to connect like links in a chain.
The technique might someday be used to tie together thousands of devices with built-in radios and make it possible to be online without having to pay for the access. It could also enable online communications in remote areas or disaster zones without Wi-Fi or cellular signals. Furthermore, the conversations in these so-called "off-the-grid" networks can't be easily hacked into by spies and mischief makers or shut down by governments trying to stifle free speech.
"We trying to create networks built by the people for the people," said Micha Benoliel, CEO of Open Garden, maker of the FireChat app.
Open Garden, a San Francisco startup with just 10 employees, is taking another step toward its ambitious goal with Thursday's release of a FireChat app for Android phones.
FireChat could be an even hotter commodity on Android given the demographic differences between that platform's user base and the typical iPhone owner. The app already has been installed on more than 1 million iOS devices.
Many smartphones running on Google Inc.'s free Android software are cheaper than Apple Inc.'s iPhone. That has made Android phones the top-selling mobile devices in less affluent countries, including in regions where Internet access is inadequate or expensive.
Google is among the big Internet companies intrigued with mesh networking's potential to bring more of the world online.
Sundar Pichai, Google's executive in charge of Android, has touted mesh networks as a way to connect wearable computers, such as the company's Glass eyewear. Mesh networks also could be used to bring a wide variety of everyday appliances online, helping to build an Internet of things instead of just websites.
FireChat's reach so far is limited. When connecting off the grid, iPhone app users have only been able to send text and photos to other FireChat users within a range of 30 to 100 feet.
Later this year, Open Garden plans to upgrade FireChat's iPhone app so off-the-grid users will be able to hopscotch through a daisy
