The Associated Press report Bill Schlough, vice president and chief information officer of the Giants, as saying: "We're charting new territory here so it's really going to be up to what our fans want."
Since the ballpark launched its wireless network in April, the first major sports venue to do so, a few hundred spectators per game have brought along their laptops or handheld computers to use the free service, Schlough said.
They're logging on to check e-mail or visit a customised website that offers live streaming video of other baseball games, statistics and historical footage.
Either way, experts say it's a sign of things to come.
"Wireless capability is in the planning docket for every major facility in professional sports because it's becoming ubiquitous in most public areas," said Paul Swangard, managing director of the University of Oregon's James Warsaw Sports Marketing Center.
In addition to instant replays, the Giants plan to add a wireless feature so fans can order food online for delivery right to their seats.
