Municipal Wi-Fi

Boston's plan to blanket the city with wireless internet access has met a series of obstacles which seriously threaten the project.

Officials in the California city of Sebastopol have gone back on an agreement with an Internet provider that was planning to create a municipal Wi-Fi network for the city. They cited health concerns in their decision.

An innovative proposal seeks to deal with both vehicle and internet congestion by placing Wi-Fi access transmitters in cars driving through urban areas.
