Radio Frequency (RF):

 

Use of wireless mobile terminals by the WMS to issue instructions to workers about what to do next and to get input back through barcode scans or key entries by the operator. The term “RF” goes back decades, from the then use of what was termed “radio frequency” technology to enable mobility, which today we think of as Wi-Fi. It was the use of RF terminals for real-time communication with warehouse software that really defined what was meant by a WMS.
