Dan Gilbert, founder and chairman of Quicken Loans Inc. and Rock Ventures LLC, confirmed today the formation of a new investment initiative, Rocket Fiber LLC, a Detroit-based high-speed Internet provider.

Rocket Fiber will provide Internet in downtown Detroit that is up to 100 times faster than the current residential average, Rock confirmed. Rock Ventures called the initiative a community investment that is "game-changing."

Construction is underway on the advanced fiber-optic Internet network that will serve residents, local government and businesses in and around downtown Detroit. Access then will be expanded to other areas of the city.

Matt Cullen, president and CEO of Rock Ventures, called the the new network "the generational leap forward" and leapfrogging where the city is at this point. It's starting in the downtown and hopefully spreading out to the neighborhoods. There is some interest along the riverfront.

The network originates west of downtown Detroit, and the initial scope covers the central business district from M-10 to the west, I-75 to the north, I-375 to the east and the Detroit River to the south.

After initial installation in downtown Detroit, Rocket Fiber will expand services to residents and businesses in Midtown along the Woodward corridor.

The system will operate on hard-wired fiber-optic lines that will be connected to buildings. Users will connect devices in their homes or businesses by either an ethernet cable or Wi-Fi. An outdoor Wi-Fi offering also will be available, Rock Ventures said.

Rocket Fiber was founded in 2014 as part of the Rock Ventures and Quicken Loans family of companies. More information on the rollout is expected to be released in the coming weeks and months.
