Most Super Bowl attendees probably won't notice, but Wi-Fi will play a big role in the operation of Miami's Dolphin Stadium. BelAir Networks' municipal Wi-Fi mesh network provides high-speed Internet access to the stadium's dining areas, executive suites and parking areas. With partner A2000 Network Solutions, the BelAir net covers more than 300,000 sq ft. The stadium bowl is supported by five nodes, while the entire network includes 29 nodes.

Among those using the Internet connections are sports reporters. BelAir nets are more commonly used in hotels and airports.
