Google said Tuesday it is teaming up with a New York City neighborhood business group to provide the company's first urban Wi-Fi network. The network will be available free to about a 10-block area surrounding Google's offices in Manhattan's Chelsea neighborhood, where Google has more than 3,000 employees. The area also is home to other tech companies, as well as high-end hotels and nightclubs and a housing project with more than 2,000 tenants.
