RedLINE - Underwater acoustic modem
Device specification

KEY FEATURES

DESCRIPTION

RedLINE - a family of wireless underwater acoustic modems that implement a transparent transmission channel.

RedLINE have an unrivalled ratio of parameters such as power consumption/dimensions/reliability and transmission range. Unified with devices RedNODE, uWAVE MAX and Zima-R monoblock design allows the use of standard solutions for integration.

Small size, low power consumption and ease of use make RedLINE an ideal solution for small-sized ROVs/AUVs as well and for larger devices.

The function of code division of subscribers allows you to most effectively solve data transfer problems for multiple devices.

1 A parameter that determines the maximum range at which a signal can be received, based on electro-acoustic parameters of the transmitter and receiver, spatial decrease in the intensity of sound energy, attenuation in the medium and the acoustic noise level.
2 This value is obtained without the presence of the multipath effect
3 Can be changed by the special request
