Designed for difficult situations

Need to communicate in harsh environments?

Water Linked's Modem M16 enhances ROV and AUV operations with reliability and robustness. By prioritizing reliability over data rate, its design ensures consistent communication even in difficult conditions, such as varying salinity, temperature fluctuations, and moderate turbidity. 


Thanks to advanced signal processing, the M16 is built to handle environments with background noise and multipath propagation. By focusing on reliability, the Modem M16 excels in scenarios where stable communication is critical, making it an ideal choice for demanding underwater applications.

Need to communicate over long periods of time? 
With a boot-up time of less than 10 milliseconds, the M16 modem can be set to sleep when not required and quickly boot-up to transmit or receive data. Where it’s not possible to set the modem into the sleep mode each modem draws less than 0.3 watts in listen mode and less than 2 watt seconds when transmitting data.


Need to communicate with other modems in close proximity? 
With 12 channels to choose from, operating around a 58.5 kHz centre frequency, multiple modems can be operated at the same time in the same area without interference. 


Need a modem on a vehicle without adding size or weight?

Maintaining a small physical size and being lightweight was critical when designing the M16 modem for optional OEM integration, allowing the M16 modem to be tightly integrated with little impact on the design of the overall system.
