There is a considerable amount of research on chaos-based communication or simply chaotic communication that has been ongoing since the early 1990's. It was argued that chaotic communication has the potential of addressing the security issue that is omnipresent in standard communication systems, yet this technology has not taken over traditional methods of communication. In this work, we provide a discussion as to why such communication system is still not fully embraced by the industrial and communication community. We give a brief survey on the existing methods for designing chaos-based communication schemes. We also propose some solutions to address this issue as well as its potential applications in 4G networks.
