This Mobile Network In A Backpack Lets You Make A Call In A Disaster

In a disaster, cell phone networks can be one of the first things to go. But cell phone networks don’t have to be confined to giant towers: The latest mobile network, from Vodafone Foundation, can fit in a backpack.

The network can’t reach very far, with a coverage area that’s only a 328-foot radius. But it’s strong enough for relief workers in a temporary office to send thousands of text messages, and make five simultaneous calls. For people who rely on their phone for banking, the device can also provide access to money. If electricity is out in the area -- a likely scenario -- the device can be charged with solar power or a car cigarette lighter.
