Modelling, developing and implementing sub-sea power-line communications networks

The development of suitable communication systems and the planning of power-line communication networks require models of the transfer characteristics of the mains network for that particular environment. Power-line communications (PLC) presents itself as an economical solution to the sub-sea and marine environment in comparison to fibre optics and others. This paper offers results of calculation, measurement and near real time simulation, which justify and fulfils the performance requirement of the present sub-sea communications. The methodology is now part of an ongoing research to establish a unique and smart approach to the design of future sub-sea umbilical cables capable of transmitting data at higher frequencies.
