Transmitters (Tx/ATA):
These antennae amplify and “broadcast” the radio waves
that will ultimately be reflected back to the receive
antennae from the RFID tags. The number of
transmitters will vary depending on the size of the store.
Normally four transmitters is the minimum number
required to cover the entire store including the Stock
Room
Receivers (Rx/ARA):
The receive antennae “listen” for the returning radio
waves that are reflected back from the RFID tags.
Normally there are 3 to 4 receivers for each transmitter in
a store.
Coaxial Cable:
The coaxial cable runs through the roof iron and connects
the Tx/ATA and Rx/ARA antennas to the MEU. The
cables are provided in four lengths: 25 feet, 50 feet, 85
feet, and 110 feet. The cable is certified and pre-
terminated with BNC connectors and is Plenum rated.
BNC Coupler:
The BNC coupler (F to F) is used to connect two coaxial
cables together. The maximum supported cable length for
Tx/ATA’s is 110 feet and for the Rx/ARA is 135 feet.
Test Tags:
RFID Test Tags are placed throughout the store to
facilitate the testing of the GOLIATH system.
