uWave Max underwater acoustic modem Device specifications |
Using uWAVE Max, the user can:
Devices from uWave family use a simple open NMEA-like configuration protocol, and the supplied open-source libraries uWaveLib (.NET) and uWave ALib (Arduino) allows for the fastest and easiest integration of devices into custom solutions.

1 A parameter that determines the maximum range at which a signal can be received based on the electro-acoustic parameters of the transmitter and receiver, spatial decrease in the intensity of sound energy, attenuation in the medium and acoustic noise level.
2 While working with uWave USBL Modem or uWave Max. Max operating range with uWave modems is 1000 m.
3 This value is obtained without the presence of the multipath effect
