Cable giant Comcast announced it will begin offering faster Internet service beginning today in certain parts of the Minneapolis - St. Paul region. Based on next-generation DOCSIS 3.0 gear, the new service will allow residential customers to get 50Mbps/5Mbps broadband service, albeit at a hefty price. The new service will cost $150/month, about triple the current cost. Along with the new tier, Comcast also plans to bump speed for current customers with the lowest tier getting 1Mbps upload speeds and the current premium tier seeing upload speed increases to 2Mbps. The new DOCSIS 3.0 technology acallows the use of four channels to send data instead of the current single channel. Comcast plans to make the service available to about 20 percent of its market by year end with the rollout to be completed sometime in 2010. The company was mum on which markets will get the new service next.
