Where to Find Low-Cost Underwater Acoustic Communication Solutions?
To address the challenge of long-distance underwater communication, our company has been actively developing and applying underwater communication modules and sensors in recent years, and has partnered with Xiamen University to accelerate product development. We have now completed the validation of a low-power, long-range, compact, and low-cost underwater acoustic communication solution.

Application Areas:
Subsea pipeline monitoring networks
Marine environmental monitoring networks
Oceanographic research sensor networks
Underwater real-time positioning systems
Short-command communication systems
Underwater unmanned vehicle communication and control

Ultrasonic underwater depth measurement / Obstacle avoidance sensors

On January 7, 2020, engineers from our company's technical department, together with members of the UAC team from Xiamen University, went to Shanzi Reservoir in Lianjiang County to conduct further underwater acoustic communication experiments, validating over a year of development on underwater acoustic communication equipment and achieving encouraging progress. Under unobstructed conditions, a strong signal was obtained at a distance of 500m, with a bit error rate lower than 0.3%.
