Here is brief description from Google of what they are planning to build:
Google is planning to build and test ultra-high speed broadband networks in one or more trial locations across the country. We'll deliver Internet speeds more than 100 times faster than what most Americans have access to today over 1 gigabit per second, fiber-to-the-home connections. We'll offer service at a competitive price to at least 50,000 and potentially up to 500,000 people.
Of course I am biased as a resident of the Baltimore area, but I truly believe Baltimore is a fantastic location for this special opportunity. It is the location of superb higher educational institutions, research facilities, science and technology industry, and highly creative and innovative residents. Baltimore has a website that supports Baltimore's bid and it includes community support via videos and Google Maps.
You can also provide support for Baltimore's bid, if interested. The deadline for submitting your support for Baltimore or any of the other towns' bids is March 26, 2010.
