Comcast will introduce a 2-gigabit-per-second Internet service starting next month in Atlanta.

Marcien Jenckes, executive vice president for consumer services at Comcast Cable, said in a statement Thursday that the Philadelphia-based media giant hopes to make the service available to 18 million homes by the end of the year.

To be called Gigabit Pro, the service "is a professional-grade residential fiber-to-the-home solution that leverages our fiber network to deliver 2 Gbps upload and download speeds," Jenckes said.

She said 2-gigabits is at least twice the speed offered by any other provider.

Jenckes did not announce a price for the service.

A gigabit is the equivalent of 1 billion bits.
