A2 RF Coordinator
This role is often called wireless microphone engineer.
An RF coordinator takes care of all the radio systems necessary for an event: not only radio microphones and in-ear monitors (iem), but also PMR walkies, intercomm, Phonak earphones, ENG crew equipment, etc. All these wireless equipment are increasingly in demand, but the rules on their use are increasingly stringent. For this reason, a wireless manager draws up an ad hoc frequency plan and chooses the best ranges for the equipment available.
The RF engineer takes care of the positioning of the antennas and the choice of coaxial cables, performs an accurate scan of the electromagnetic spectrum that can be exploited in the location. In the most delicate cases, an inspection will be necessary to be carried out in the days preceding the event.
RF coordinator must check if there may be radio frequency interference with led walls and motorized movement and must be aware of the regulations in force in the country where the event will take place (in Italy, the MISE).
