S1000N - Featuring UnetStack by Subnero

Popoto Modem and Singapore-headquartered Subnero have joined forces to create a powerful new underwater acoustic modem, the S1000-N. This modem combines the best from both companies, bringing together the power of the Popoto Modem’s S1000 series modems and Subnero’s underwater network stack (UnetStack) to enable you to build advanced underwater networks today!

With the S1000-N, users can enjoy a data rate of up to 10240 bps over a range of 3+ km. Subnero's technology integration allows users to take full advantage of UnetStack, an underwater networking stack with features such as multi-hop routing, fragmentation & reassembly, contention-free communication, and much more, providing users with a more reliable and efficient way to send data underwater. With a fully functioning network stack out of the box, the S1000-N offers users a powerful and affordable solution for underwater communications.

The Popoto S-series of modems represent an industry breakthrough in performance and affordability. The S-series has reliable data transfer at multiple bit rates starting at 80 bps all the way to 5120 bps (coded) and 10240 (uncoded). Easy to use API's such as Python, Matlab, C++, or socket based JSON along with multiple hardware interfaces such as RS-232, RS422, ethernet, and GPIOs make this modem easy to integrate and use. This slim modem is able to transmit at up to 20W. The Popoto S-series also gives sub-meter accuracy using two way ranging so you can always know the distance to your modem.

If you are looking for an affordable solution for acoustic comms with multiple modems, the Popoto S-series is the peak of the curve.
