Abstract
A wearable mobile computer communicates with a headset worn by an operator using a communication channel established between the computer and a radio frequency identification (“RFID”) tag located in the headset. The headset may be configured for receive only (voice travels only from the computer to the headset) or configured for two-way voice communication. For two-way communication backscatter from the RFID tag is used to carry voice signals.
