From section 3.14.3 Pit and Competition Safety

Two-way radios: Not allowed in the Pit or near the playing field since they may interfere with robot operation and cause accidents.

That's interesting. How about the old radios? Is there something in its makeup where cell phones dont have a strong enough signal to affect them.
I made that statement earlier based on an earlier post, then had our whole team use their cell phones near the robot with our old radios. It didnt encounter any loss signal between the OI and RC.
What's different internally with these new radios?
