Comcast invests in mobile broadband firm

Comcast is making more inroads in mobile broadband. The cable firm made a seed-round investment in Littleton, Mass.-based startup Cartiza Networks, which is developing an IP-based content management and delivery system for mobile broadband networks. Cartiza raised $12.6 million in venture capital funding in 2007 and its investors include Comcast Interactive Capital, Prism VentureWorks and the Business Development Bank of Canada. The company reportedly is in "stealth" mode and has not publicly discussed its technology or strategy. However, the firm is a member of the WiMAX Forum.

The investment is interesting considering Comcast's other mobile broadband plays--most notably its investment in the new Clearwire. In May, Sprint and Clearwire announced that they will combine their WiMAX businesses and create a new company, called Clearwire, that will include a $3.2 billion investment from Intel, Google, Comcast, Time Warner Cable, Bright House Networks and Trilogy Equity Partners.
