VOK-REF
Communication system for referees and team sports officiating.
VOKKERO "VOK-REF" is a wireless audio conference system that has been developed to satisfy requirements specific to referees of team sports and trainers: to keep them in permanent contact so that they may quickly intervene in collaboration with one another.
This system does not need a fixed installation, and can be used instantly. It makes it possible to set up continuous hands-free communication between referees and their associate judges for the entire duration of a competition.
This audio solution represents a unique combination of 3 technologies (hands-free conference call / encryption / noise filter). It ensures simultaneous communication between 5 users without requiring any buttons to be pressed to during the conversation. A high performance noise filter minimizes the background noise of several thousand fans..
The VOK-REF was initially developed in 2005 based on specifications from the French Professionnal Football League (LFP) and from the French soccer referee committee, and has been used since by the world's greatest soccer and rugby referees during events as important as the European Champions League, the 2006 soccer world cup in Germany and the 2007 rugby world cup in France. It has now become an essential tool for Ice Hockey, Basketball, Lacrosse, Football, Rugby or just about any in-game officiating communication application. The System is easy to set up, completely portable, light weight and unobtrusive to the referee.
