The World League of American Football has approved the use of radios in quarterbacks' helmets for its first season, which begins in March.
Tex Schramm, the league's president, had hoped to get the innovation into the NFL when he was president of the Dallas Cowboys.
"Technological innovations will be a trademark of the World League," Schramm said.
Schramm said the coaches' ability to communicate with their quarterbacks by radio will be a boon to the no-huddle offense.
"Not only will this heighten the excitement level with a final two-minute style of play, but it will speed up the tempo and shorten the overall playing time of our games without decreasing the number of plays," Schramm said.
