SoundLink Underwater Acoustic Modem（UWM）

The advanced acoustic bandwidth spread spectrum technology is used in the acoustic communication produced by LinkQuest. The underwater acoustic data modulation and demodulation system provided by LinkQuest can effectively overcome the problems of low reliability, low data rate and high power consumption of traditional products in underwater communication.

Product Description The Underwater acoustic Data Modulation and demodulation system is a bidirectional, half-duplex underwater acoustic communication system used in fresh water or sea water. The maximum vertical distance of narrowband acoustic communication is up to 1500 meters, the maximum degree of the bottom unit is up to 1000 meters, and the maximum depth of the water unit is up to 200 meters. The advanced technologies obtained so far are summarized as follows:
The data rate is significantly increased to 38400 bit/s
Bit error rate is less than 10-9
The power consumption is effectively reduced
