Характеристики

uWAVE is the world smallest underwater acoustic digital modem, which allows to communicate up to 20 subscribers in area 1000 x 1000 meters with both transparent channel and predefined code messages/telemetry transmission. 
Extremely small size, low power consumption and simplicity of usage make uWAVE an ideal solution for AUV control as well as data transmission, where dimensions and wight are the bottleneck.

Key features:

  • Extremely small size and weight
  • Can be applied in underwater wireless sensor networks
  • Reliable data transmission with 78 bit/s
  • Operating range up to 1000 m
  • Subscribers code division
  • Propagation time measurement
  • Reliable and noise-immune technology of digital broadband acoustic communication
  • Low power consumption (Rx/Tx) 0.33/6 W
  • Open configuration protocol
  • Built-in depth/temperature sensor
