Thanks to the revolution in electronics and telecommunications, there is a proliferation of devices for medical applications and others operating in the body area. There is a novel way to connect two transceivers with the human body as a communication channel by body capacitive coupling. BCC (Body Coupled Communication) is a technology that uses the human body as an electric field propagation medium without using wires or RF technology. This work aims to design and implement a BCC audio transmission system by using the USRP1 hardware and GNU radio for the design, in this work we use measure the body channel frequency response by using a signal generator and an oscilloscope and we used a portable VNA to measure the impedance and verify the data. We were able to transmit at a bit rate of 128 Kbps.
