FireChat gives users a way to connect off the grid

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 myriad devices to connect like links in a chain.

The technique might 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're 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.

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 chain of devices to extend the reach of a local network.

If this works, a FireChat user sitting in the right-field bleachers of a baseball game would be able to text with a friend on the other side of the stadium if enough other iPhone users in the ballpark also are on FireChat.

This extended range will be available immediately on FireChat's Android app because Open Garden released a mesh networking app for that operating system nearly two years ago.
