uWave Max hydroacoustic modem

uWave Max provides digital hydroacoustic communication between 254 subscribers: in code mode, transparent channel mode, or packet mode with logical addressing and guaranteed delivery. Extremely small size, low power consumption and ease of use make the uWave family of modems a solution for controlling autonomous underwater devices and transmitting data in size- and weight-sensitive applications.

The device lets you: transmit data in transparent channel mode (simply connect the modem to a serial port); request the depth, temperature and supply voltage of remote uWave family modems, with simultaneous measurement of the signal propagation time (and hence the distance to them); transmit data in packet mode with guaranteed delivery (ALO — At-least-once) and delivery notification; and measure its own immersion depth, water temperature and supply voltage.

Devices in the uWave family use a simple NMEA-like configuration protocol, and the supplied open-source uWaveLib (.NET) and uWave ALibs (Arduino) libraries make it as simple and fast as possible to integrate the modems into custom solutions.

Differences from the base uWave version: maximum communication range increased to 3000 m (when working with another uWave Max, uWave Max OEM or uWave USBL; with standard uWave modems the range is 1000 m). The monoblock design is patented (patent RU2659299C1).
