Comcast on Monday announced that it will launch its 4G mobile broadband service in the Portland area via the Clearwire network starting Tuesday.

The service, dubbed 2go, will only be available if bundled with one or more of Comcast's Internet, phone, or cable services.

Comcast is offering two data cards and service plans: 2go Metro, which offers 4G service in the Portland area; or 2go Nationwide, which offers 4G service in Portland, and 3G service nationwide via Sprint's network.

The 2go service will be bundled in "Fast Pack" offerings.

Fast Pack Metro will be available for $49.99 and includes Comcast's 12 Mbps Internet service, a Wi-Fi router, and 4G service with up to 4 Mbps download speed. Fast Pack Nationwide will run $69.99 per month with the same services, plus Sprint nationwide.

Triple Play customers who subscribe to voice, cable, and Internet will be able to add 2go starting at $30 per month.

A version of 2go will also be available for small- and medium-sized businesses.

In May 2008, Sprint agreed to take over the combined WiMAX operations of Clearwire in a deal backed by tech titans Comcast, Google, Intel, Time Warner Cable, and Bright House Networks. In June 2009, Clearwire quietly launched its Clear WiMax service in Las Vegas today, but Sprint demurred, keeping the two companies' WiMax systems still separate for now.
