Bay Area nonprofit Green Wi-Fi's solar-powered networking gear is designed to provide wireless broadband access in developing countries where sources of electrical power might be unreliable or nonexistent. Here is the latest version of the organization's Wi-Fi's access node, which consists of a small solar panel, a heavy-duty battery, a router and an "intelligent" charge controller that moderates power use based on sunlight intensity. The network is designed to automatically limit broadband access when solar-power levels are low, which enables the system to stay in continuous operation for as long as a month in weak sunlight.
