The successful use of the Minneapolis Wi-Fi network to aid rescue workers following the collapse of the I-35 bridge is a textbook case of how this technology can aid public safety efforts, according to those involved.

The only portion of the network built so far covered downtown Minneapolis, including the south portion of the bridge and riverbank. Following swift action by Joe Caldwell, CEO of U.S. Internet, to disable the paid log-in process, the Wi-Fi network was made available for data transmission and voice-over-IP calls. That access became important when the cellular network was overwhelmed almost immediately by the volume of calls. Caldwell also sent in additional access points and wireless video cameras to aid the rescue efforts.

Lynn Willenbring, chief information officer for Minneapolis, said that city officials used the network to distribute geographic information system maps to both rescue workers and to the public to address traffic and recovery efforts.

“I think this is a very stark example that people, as they find out about it, will help them understand and see how having government as anchor tenant makes a lot of sense,” said Craig Settles, president of Successful.com and a researcher in this area. “Other cities need to look at that and think, ‘We need to look at this technology.’”
