Today Google Fiber began taking signups in Salt Lake City, Utah, the gigabit ISP's seventh metro area.

Gigabit Internet will be available for $70 a month and 100Mbps will cost $50 a month. Gigabit Internet with TV service is $140 a month. There are no data caps on any of the tiers. Phone service can be added for $10.

The initial deployment "will cover roughly 112 blocks from 100 South to 800 South between 400 West and 1300 East," The Salt Lake Tribune reported today. Assuming demand is high, installations "could take a week or more after customers apply." Google Fiber said that other parts of the city will get the service within months but offered no more specific timeline.

Comcast in Salt Lake City offers its 2Gbps fiber service, which costs $300 a month with up to $1,000 in installation and activation fees. Comcast's somewhat cheaper gigabit cable service hasn't rolled out to Utah yet.

Google Fiber was already available in Atlanta, Georgia; Austin, Texas; Charlotte, North Carolina; the Kansas City metro area in Missouri and Kansas; Nashville, Tennessee; and Provo, Utah. Google Fiber lists another 16 metro areas where it has either firm or tentative plans for expansion.

Whether those expansions will use fiber or wireless is an open question, however. Google Fiber is considering using point-to-point wireless technology to quicken deployment, with the purchase of wireless ISP Webpass. But while Webpass' wireless service provides fiber-like speeds, it's designed for multi-unit residential buildings and businesses rather than single-family homes.
