Frequently Asked Questions

Q: What is the S1000-N acoustic smart modem?

A: The S1000-N is a new underwater acoustic modem that combines the power of the S1000 series modems from Popoto Modem and UnetStack from Subnero. The modems will have a fully functioning network stack out of the box, and offer a data rate of up to 10240 bps over a range of 3+ km.

Q: What is the advantage of combining the power of Popoto's S-series modems with the network stack of UnetStack?

A: By combining these two technologies, the S1000-N offers a truly advanced underwater acoustic smart modem that is both compact and affordable. The modems are ideal for use in a wide range of underwater applications that need flexibility and affordability.

Q: What are the key features of the S1000-N modems?

A: The S1000-N modems offer a data rate of up to 10240 bps over a range of 3+ km, multihop routing, low power operations, and arbitrary waveform transmission and reception.

Q: What is multi-hop routing?

A: Multihop routing allows the S1000-N modems to communicate over longer distances than traditional acoustic smart modems. This is achieved by using a series of intermediate nodes to relay data between the source and destination.

Q: What application domains are the S1000-N modems ideal for?

A: The S1000-N modems are ideal for use in scientific research applications. They offer a reliable means of communicating underwater, and their low power consumption makes them ideal for use in applications where power is at a premium, all of this with affordable pricing.
