I had 3 wifi networks at my voting location. I emailed the county elections office and QUICKLY received this reply (which I thought was mildly intelligent and HOPEFULLY true):
Thank you for emailing us. That is a very good question you asked. The WiFi device that you saw (from AT&T) is not only password-protected but it's configured such that no other devices can even see it as a wireless option except for the Electronic Pollbooks that we use to check-in voters. If anyone were to take out their phone and stand next to the WiFi device, they wouldn't see it as an available WiFi device.
To further clarify, only voter turnout data is submitted through the WiFi device back to the main Board of Elections headquarters downtown. Any information that is sent is the same information that is public information (i.e. who voted) that we post on the entrance to a polling location at 11 a.m. and 4 p.m. NO VOTE TOTALS ARE SENT ELECTRONICALLY. How a person voted is only contained on the paper ballot, and within the scanner that scans the ballot. Those scanners are never connected to the internet.
It is trival to configure your wifi router to not broadcast its SSID.
It is not necessary to broadcast the SSID in order to connect to it. It is just a human convenience.
Which I assume any election fraudster would know.

I'm no wi-fi expert, but I assume no.
If you don't know the SSID independently, then you aren't connecting.
You may find this to be a good read.
Assuming fraud is the intent, a wifi connection need not be present while voting is happening, merely during counting.

I hope this answers your question.
It used to be part of my job to detect all SSID's at customer sites. I used the free version of a tool called InSSIDer.
