Eventually, they decided they could do it. And that took some engineering work. Perhaps most importantly, the headsets are light, comfortable, and durable. The intercom device that transmits that message to the quarterback or defensive player is provided by Green-GO, a European company that specializes in wireless intercom systems. The biggest challenge with the radio system has been coordinating all the frequencies, Cave said.
There is only so much bandwidth, however, which meant some frequencies had to be shared. The coaches had been told to make sure all their headsets were turned off at halftime, and the performers were given the same message for once they were done, but there was always the chance someone would forget.
The exclusive frequency is encrypted and highly secure, so stealing signals is now impossible. The frequency is much higher than anything that would get interference from a radio broadcast or a delivery boy, once a common occurrence. There are still occasional problems. Ear Rockers shares that some Cleveland Browns fans invented a radio device for the Browns quarterbacks to use. The Browns used it in a game against the Detroit Lions, but their coach complained and got the devices banned.
Once the ban was lifted, the use of a headset was restricted to only two players: the quarterback on offense and a linebacker on defense. For years, it was tough because the headsets worked with radiofrequency.
They were one of the best headset manufacturers for noise-canceling technology. Thanks to that deal, communication between coach and player is easier, even with a loud stadium. That sticker signifies that the player wearing it has radio communications with the coach.
As mentioned before, only one player on each side of the ball may have a radio. Only the quarterback will have the sticker on offense. On defense, it depends on the play. But in a nickel package, the best linebacker might be out of that play.
In this case, the alternate player will have the green dot on their helmet instead. The green sticker is just so that officials can ensure that only one player on each side of the field has a headset in their helmet.
When a player designated to wear a headset helmet leaves, the substitute has to let the referee know that they will be the one receiving communications.
You know, the ones with weird logos and emojis and photos of cats on them. They told us about the advantages and challenges the technology presented at the time. Helmet radios have changed the game for offenses and defenses thanks, Spygate! Currently, the NFL or professional leagues are the only ones that use communication technology. Here is a great video made by Sports Nation which details a timeline of when the audio speaker was first implemented into the helmet.
This is very important to understand. There are a set of rules the NFL has established with the headset communication:. No, the coach talking to the player must be a sidelined coach — meaning the coach in the booth cannot communicate with any player on the field through a speaker in a helmet. This is for, as mentioned above, the coach not mentally playing the game for the quarterback as the coach will have a perfect birds-eye view of the game.
They are only allowed to talk to the player once the play ends and the new play clock begins. However, the new XFL tried out consistent communication with having the speakers live at all times for the quarterback, and it seemed to pan out well. If this happens, teams are usually prepared to have a backup system in place of either using hand signals, having an offensive player run in the play, or, worst case, having the quarterback go to the sideline to get the play from the coach.
