TechAssist will provide free wireless Internet access in the Dupont Circle are of Washington, DC, starting Friday. The wireless access will work inside the area and may work on surrounding blocks. The project will cost approximately $10,000. TechAssist does not have plans to make up that cost by using advertising on its website. The company considered other parts of the city but eventually settled on Dupont Circle. TechAssist will consider installing wireless access in Adams Morgan and McPherson Square in the future. Story
