It seems to me that they were just giving the details of an RFID chip. Both chips are passive. RFID chips run off of UHF radio frequencies. It just so happens here that Disney wants to use a different radio frequency for these RFID chips. RFID chips do transmit data through radio waves.
The wireless infrastructure is just that. A chip communicates with a receiver and creates a wireless connection. That receiver then is connected to the central database of information.
