This is a religious event held in São Paulo every year since 1993. The event consists of a walk from Tiradentes square to Campo de Bagatelle square, accompanied by a sound truck (trio elétrico).
At the final destination, a live concert takes place at a stage that is set specifically for the event. Systec has been participating in this event since 2009, assembling an integrated communications system for reporters, cameras, TV producers, etc. through its O.B. van - iCar.
The biggest communication challenge posed by this event is to establish a link between the production center and the moving sound truck where the event's interviews and recordings are made. It is a three-kilometer stretch and there can be no communication problems.
