Subject’s body posture for channel gain measurements: (a) the subject holds the portable transmitter (Tx) with its signal coupler in contact with the wrist of one arm, and the portable receiver (Rx) at the wrist of another arm, while emulating a T-pose and various postural variations to capture variability in channel capacity. b Portable Signal Generator used as the transmitter. ESD wrist bands used as couplers to couple the signal to and pickup from the subject’s body. Portable Spectrum Analyzer used as the receiver. The receiver setup includes handheld spectrum analyzer together with Buffer. c Customized Buffer with high impedance capacitive termination for voltage mode communication. d Schematic of the measurement system.
