Three wireless networks and a 114-mile fiber-optic network will be in place by game time to serve 100,000 fans converging on the city and 90 million TV viewers, Sprint officials said.

Sprint has completed a data distribution system to support Ford Field, Cobo Hall, the Jose Louis arena and downtown Detroit. Its construction has been under way for a year and will be used on game day primarily to authenticate tickets at the field and remote areas, said John Polivka, a Sprint spokesman.

The fiber-optic capacity and that of the three other networks will stay in place to provide added capacity for Detroit residents and visitors, he said.

In addition, Nextel walkie-talkie service capacity is being increased nearly 300 percent with the addition of 500 additional base radio transmitters, Sprint said. Also, Sprint's PCS cellular coverage and capacity at Ford Field and nearby is being doubled.

Sprint has also powered up its newer Evolution-Data Only (EV-DO) technology to the Super Bowl venue and the city for improved bandwidth. Sprint calls its EV-DO, or third-generation technology, Sprint Power Vision.
