RedLine underwater digital acoustic modem

RedLine is the series of wireless underwater digital communications modems that implement a transparent transmission channel.

RedLine modems have an unsurpassed correlation of such parameters as power consumption, dimensions, speed and transmission distance.

One-piece housing unified with a RedNODE devices allows you to use standard solutions for integration. Small size, low power consumption and ease of use make RedLine ideal solution both for small ROV/ AUV and larger devices. Subscribers code division feature allows solving efficiently the data transfer tasks for several devices.

Key features:

  • Can be applied in underwater digital acoustic sensor networks
  • Reliable data transmissions with 88 bit/s
  • Minimum dimensions
  • Operating range up to  8000 m
