What is USSF policy on the use of headsets in non-MLS matches? Is their use permitted by officiating crews? If so, what information should be transmitted over them, and should transmissions be encrypted?
USSF answer (April 7, 2009):
The headsets are considered to be part of the referee uniform and their use requires the permission of the Referee Committee. If headsets are used, the only information that should be exchanged among the officiating crew would be game-related. And unless the refereeing crew wished to share the information with the world, encryption would be appropriate.
