Wi-Fi Planet's Adam Stone today looks at BelAir Networks' deployment of wireless connectivity in Dolphin Stadium, home of the Miami Dolphins and the Florida Marlins. "In addition to high-speed Internet access in all dining areas and executive suites, the stadium now boasts what BelAir describes as the largest wireless point of sale system under one roof," Stone writes.

According to BelAir's Jim Freeze, many of the stadium's hot dog carts and other points of sale are still wired, but about 35 percent are now wireless. And customer service in the executive suites is greatly improved. Instead of having a server write down a drink order and then go to a bartender to order that drink, the server can type it into a handset -- and, Freeze says, "within milliseconds of it being typed, it gets to a bartender who's started to make those drinks."

"There is still a perception that Wi-Fi is a 'nice' technology and it's nice to have it on your home router," Freeze says. "But in fact, with the right implementation and some engineering magic, it provides real value. Wi-Fi is ready-for-prime-time technology. There are still some who view Wi-Fi as not being able to handle these kinds of applications but Wi-Fi definitely can handle it. It's not just toy technology."
