TechWeb - "Minneapolis is the latest large U.S. city to commit to building a citywide wireless network, but the city will hedge its bets by rolling out Wi-Fi initially and retaining the capability of upgrading to WiMAX and 3G at a later date. In an announcement Tuesday, suppliers BelAir Networks and US Internet said the deployment will cover a 54-squre-mile sector of the city. "The network is modular architecture," said Sheila Burpee Duncan, BelAir spokeswoman. "You want it to be futureproof." Duncan said a one-mile-square Wi-Fi pilot network is already up-and-running. The next step will be to deploy Wi-Fi across the city. She noted that Wi-Fi operates in unlicensed spectrum, making it easier to rollout the wireless technology quickly. US Internet, a leader in mesh networking integration, will deploy the network. "
