CAPE COD, Mass.–(BUSINESS WIRE) - Popoto Modem is pleased to announce the first low cost, small-scale, JANUS compliant underwater acoustic modem target for OEM solutions. This flexible modem board-set measures 60mm x 90mm and features a 100-watt transmitter and an ultra-low noise receiver utilizing sophisticated DSP technology by Texas Instruments. By implementing the JANUS standard for undersea telecom, this modem maximizes interoperability with the outside world.

“We believe we have created an exceptional modem, achieving low cost, small size, and high ACOMMS reliability. We are eager to help our customers integrate it and become innovators in this new ‘internet of underwater things’’

In any communication system, standardization is fundamental. A common mechanism or language must be followed on both ends of the system for successful data transmission. In March 2017, NATO released ANEP-87 Digital Underwater Signaling Standard for Network Node Discovery and Interoperability (JANUS…

US-based 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.

One of the key features of the S1000-N is its ability to operate at a low power…
