We’d heard this project was underway but now it’s official: AT&T and Aruba Networks are the forces behind a new Wi-Fi network at the American Airlines Center in Dallas, a 21,000-seat facility that is home to the Dallas Mavericks of the NBA and the Dallas Stars of the NHL. According to an AT&T press release put out today the new Wi-Fi network will have 315 access points, bringing more connectivity to the AT&T DAS that has already been in place at the arena since 2012.
