InfoWorld: Cisco plans high-tech ballpark for A's

Cisco Chief Executive Officer John Chambers hosted a news conference Tuesday at which he was joined by A's owner Lewis Wolff, Major League Baseball Commissioner Bud Selig, and others to unveil plans for a proposed US$400 million to $500 million ballpark in Fremont, California, 22 miles south of the current home of the A's in Oakland, California.

The 34,000-seat Cisco Field will feature a wireless network on which fans can use handheld devices to watch instant replays, order food and beverages, communicate with friends and keep score. Fans will be able to buy tickets online, receive their ticket as a file on a smartphone to show at the gate and visit kiosks inside the stadium to upgrade to nicer seats. Stadium employees will use other handheld communicators that use radio-frequency identity (RFID) technology to locate and talk to each other.
