From Air-Grid Networks, a new service where, for around $20, fans at major sporting events can rent a Tablet PC with an 802.11a wireless card which they can use to watch instant replays of the game from their seat in the stands:
Users will be able to choose from four different camera angles — from a combination of broadcast network and team camera positions. They’ll also have the option of viewing in slow motion. Air-Grid will process video clips in near-real time as the game goes on, pushing out announcements over the wireless network that will scroll across customers’ tablets to let them know a new replay is available. The firm generates 10 to 12 replays per quarter of a basketball game.
You should also be able to use the WiFi Tablets to watch broadcasts of other games being played at the same time, access statistics, and, of course, order beer and hot dogs. Air-Grid claims they’ll have at least one Major League Baseball team signed up as a customer by July.
