Yes, somebody could still have a rouge FTC_Field network in the stand, but any robot that has been inspected would only connect to the correct wifi network.
This doesn't mean that somebody cannot "play" the system and use it to their advantage. I am not going into details into some of the scenarios that my FTA has shared with me.

The samantha will attempt to connect to the FTC_Field network with the strongest signal strength - from my experience, testing the samantha with two APs broadcasting FTC_Field with different passwords. Even after the samantha is given a password to use, it might just continue attempting (and failing) to connect to the rouge FTC_Field.
Now I would hope the samantha, once it is initially connected to the correct FTC_Field and FCS, would stay locked in through whatever protocol it uses to identify with the FCS but after seeing robots randomly disconnect I do not think that the protocol has this kind of a lock built in.
Random Dude's solution, I believe is the best. You might want to set your AP's to have hidden network names so that someone can't change their networks's SSID to be the same as yours. Are the FTA's allowed to change the initial configuration file that is put on the samantha during inspection? When my team was inspected (one of the first teams), the USB drive was taken out what looked like official packaging.
Regardless of all of that, if someone is trying to create problems with wifi, especially from the stands, they will likely fail because of signal strength. The fields are much closer to the official AP's than they would be to any rouge AP's (or at least they should be). Now there are signal focusing and boosting devices, but they should not be too hard to spot.
