Google Inc. and EarthLink Inc. submitted a joint bid to offer free wireless Internet access in San Francisco, a venture that might spark new competition for Comcast Corp. and AT&T Inc.
Under the proposal, Google would provide a free service sponsored by advertising and EarthLink would offer a paid service with higher access speeds, Donald Berryman, president of EarthLink's municipal networks unit, said. The bid was one of six offered to the city by Internet access providers.
