Comcast to offer 4G wireless broadband service
The largest cable operator in the U.S. will launch the new service in Portland, Ore. And it will expand the service to other Comcast cities later in the year, including Atlanta, Chicago, and Philadelphia. Comcast invested in the new Clearwire in 2008, along with Google, Intel, Time Warner Cable, and Sprint Nextel, which gave Clearwire its 2.5GHz spectrum.
