How does FIRST make sure that robot signals don't interfere with each other? Correct me if I'm wrong, but I believe they have 4 wireless channels available to use, one for each robot. For regionals this seems fine as there is never more than 4 robots operating in a match at the same time. However, at nationals they have 4 divisions equaling the potential of 16 (4*4) robots running at the same time! Does FIRST unlock extra channels for nationals, are the fields far enough away that they don't interfere, or is it something else entirely

?
I guess I'm interested in the technical administration aspect of running a FIRST competition, especially nationals due to the high volume of teams, but finding it hard satisfy my curiosity! So, as a side note, does anyone have any info on this, or know where
I can get some? I would really appreciate it....... Thanks!:
