Which voting equipment has wireless communication capability?

[Fly by night]

I've heard from the Chairman of our State Election Commission (Tennessee) who asked which voting systems are configured with wireless communication capability. I know that the ES&S precinct-based optical scanner is (because the ES&S rep told me so.) I presume that the ES&S central-based optical scan also has wireless capability.

How about any of the central tabulators that are used with DREs from Diebold or other companies? We really seem to have their interest to ban or disable any wireless communication capability in all voting equipment, so as complete a list as possible would sure be appreciated. That includes any DREs that might also have wireless communication.

Thanks kindly. I'm trying to keep working on election reform issues up to the last minute, as I pack for the "big day" tomorrow.
