RedGTR is the series of wireless underwater digital communications modems that provide short code messages exchange in a network organized between such devices.
The device uses a fixed-length code-division signal to provide a point-to-point network consisting of 25 devices located in the same water area up to 8000×8000 meters. Up to 40 code messages in a network of 25 subscribers.
One-piece housing unified with a RedNODE device allows you to use standard solutions for integration. Small size, low power consumption and ease of use make RedGTR ideal solution for the implementation of control channels, as well as signaling devices for various actuators, circuit breakers, and other actuators.
