Comcast Increases Upstream Speeds for Its High-Speed Internet Customers for No Additional Charge.

Upstream Speed to Nearly Triple for Customers with 6 Mbps and More than Double for 8 Mbps Customers

MIRAMAR, Fla. -- Comcast, South Florida's leading provider of entertainment, information and communications, announced today that it is increasing upstream speeds locally for its residential high-speed Internet customers at no additional cost to comcast.net customers.

Comcast will nearly triple the upload speed of its 6 Mbps/384 Kbps tier to 6 Mbps/1 Mbps and more than double the upload speed of its 8 Mbps/768 Kbps tier to 8 Mbps/2 Mbps.

"As the Internet evolves, so will our services and offerings," said Filemon Lopez, Comcast's Senior Regional Vice President for South Florida. "We've been proactive by making a number of complimentary speed increases over the last few years. This time we focused on increasing upstream speeds so our customers can take even better advantage of the ever-expanding amount of interactive applications the Internet has to offer."

Along with increased upstream speeds, Comcast customers can still enjoy faster download speeds with Comcast's PowerBoost[TM] technology, also at no additional cost. With PowerBoost technology, Comcast customers can get up to 12 Mbps downloads on the 6 Mbps tier and up to 16 Mbps downloads on the 8 Mbps tier for files such as videos, games, music and digital photos.

Increasing upstream speeds is one of several speed enhancements Comcast has implemented in 2008. Earlier this year, Comcast announced it would be evolving from broadband to wideband with the deployment of DOCSIS 3.0 (Data Over Cable Service Interface Specifications) technology, which sets a new standard for delivering high-speed Internet service across fiber-optic cable networks. Comcast recently launched its first DOCSIS 3.0 market in the Twin Cities, offering residents and businesses one of the fastest broadband services available in the U.S. today: with up to 50 Mbps download speed and 5 Mbps uploads. Comcast expects to deliver even faster speeds of up to 100 Mbps to its customers over the next two years with the capability of delivering higher speeds of 160 Mbps or more in the future.
