Wireless network via street lamps

"CIO — Researchers at Harvard University and BBN Technologies have designed an intriguing wireless network capable of reporting real-time sensor data across an entire city, Cambridge, Mass. Scientists will initially use the CitySense network to monitor urban weather and pollution. The network could eventually provide better public wireless Internet access. "

They plan to install 100 nodes by 2011 in the Cambridge area, and have nodes transmit data by forming a mesh with surrounding nodes.

"Each node will include an embedded PC running the Linux OS, an 802.11 Wi-Fi interface and weather sensors, says Matt Welsh, assistant professor of computer science at Harvard."

This project will let researchers worldwide log in and submit experiments to be run on the network.
