Abstract

The present invention relates to quasistatic electromagnetic field communication system and method for performing quasistatic electromagnetic field communication through a chassis body of connected devices. The method includes transmitting, by a transmitting power source, data signals to connected devices through the chassis body associated with the connected devices. The method then includes performing, by the transmitting power source, excitation of the chassis body based on the transmission. Further the method includes creating, by the chassis body, one or more quasistatic field signals upon the excitation of the chassis body. Furthermore, the method includes receiving, by a receiving device, the one or more quasistatic field signals from the chassis body. Furthermore, the method includes performing, by the receiving device, filtration of the received one or more quasistatic field signals by filtering the one or more quasistatic field signals which are out of predefined operating range.
