The Pittsburgh Vintage Grand Prix set up a temporary network using BelAir equipment for the weekend of the race: Race organizers were able to compile race results and post them on monitors in the pit and stands so drivers and spectators could quickly see results. Previously, race results were compiled and distributed on paper, a several hour affair.
Because the race organizers used monitors to display the results to users, this application is potentially more useful than those that require spectators to use their own laptops or PDAs to access data. The baseball field hotspots have sometimes been criticized by people who can't imagine fans bringing their laptops to games in order to access stats.
