Comcast Corporation, one of the nation's premier providers of entertainment, information and communications products and services, introduced XFINITY Internet 2go, high-speed wireless data service in the Sacramento, Calif. area.

Last month, the service was also launched in Stockton, Modesto, Lathrop and Visalia.

A mobile Internet solution via wireless data cards is provided by Comcast's (News - Alert) XFINITY Internet 2go. In addition to a nationwide 3G wireless service, Comcast offers 4G wireless services. This wireless service is being sold by Comcast independently or as an add-on with one or more of its popular XFINITY Internet, XFINITY TV or XFINITY Voice products, providing mobile broadband wherever and whenever customers need to be connected.

"California is known for its progressive cities that embrace technology and Comcast is proud to bring 4G and 3G wireless service to consumers who are on the go," said Curt Henninger, regional vice president for Comcast's California region, in a press release. "Comcast continues to drive innovation in the market whether it's with video, voice, the Internet or now wireless – all for the ultimate benefit of customers in the region."

Three different data cards and service plans are being sold by Comcast. Some of them are:

XFINITY Internet 2go Metro service uses a 4G-only data card, giving customers super-fast wireless service within the 4G metro coverage area. The 4G device operates only in a 4G network footprint.

XFINITY Internet 2go Nationwide service uses a 3G-only data card, giving customers nationwide wireless service. The 3G-only device operates on Sprint's (News - Alert) national 3G network.

XFINITY Internet 2go Nationwide Preferred service delivers fast metro 4G service plus coast-to-coast access on Sprint's national 3G network. The 4G/3G device operates by switching between available 4G and 3G networks.

In related news, Brian L. Roberts, chairman and CEO of Comcast Corporation, will participate in Citigroup's 21st Annual Global Entertainment, Media and Telecommunications Conference, being held in Phoenix, Ariz.
