Performance Measure on Efficient Wireless Data Transfer in Highly Conductive Medium

Efficient radio waves propagation with associated data transfer in conductive seawater is yet a challenge due to high attenuation as compared to air. The domain needs room for improvement for larger data transfer distance (>1m). If improved, the applications include marine activities and offshore oil and gas industries will be in a greater benefit. This paper presents an experimental design for data transfer link using conduction current method. The gain and the filter are well-calibrated for the frequencies ranging from 10kHz to 1 MHz with varying baud rates. Performance analysis of the experimental design using electrodes based transmitter system enabled authentic data collection with enhanced configurability. Evaluating Bit Error Rate (BER) while varying data speed and varying transmission distance revealed that at the constant carrier frequency and circuit tuning BER increases up to 88% upon increasing the data rate (10 KHz). Similarly, on increasing electrodes separation, the acceptable higher data rates are received with slightly less efficiency than the received signal at lower data rates.
