We need a mobile broadband space race

Due to a reporting error, the story "We need a mobile broadband space race," posted Monday, incorrectly said the Sprint 4G service would be tested in Baltimore starting this month. In fact, the service is already publicly available in Baltimore.

The story has been changed on the wire and the 10th paragraph now reads:

Although U.S. carriers are working on 4G and WiMax -- Sprint Nextel Corp., for example, launched WiMax services in Baltimore in September -- the nation is way behind in all aspects of mobile broadband.
