There are several prohibited items and the rules are strictly enforced. You are not allowed to bring glass bottles and cans into the ballpark. Alcoholic beverages of any kind, including wine and non-alcoholic beer, are not permitted, either. You may not bring a weapon with you into AT&T Park. And while banners and signs are welcome at the ballpark, they cannot be higher than three feet.
Not only is Wi-Fi available, you'll have continuous access whether you're sitting in your seat or standing in line for a hot dog. With nearly 1,300 access points, the San Francisco Giants have created one of the world's largest public hotspots at AT&T Park. So bring your Wi-Fi-enabled smartphone, tablet, laptop or PDA out to the ballgame and you'll be able to stay connected absolutely free.
