S40H uses 25–50 kHz and is marketed for short-range image transfer and data offload. Subnero specifies up to 33 kbps in shallow tropical waters and range up to 1 km, conditional on channel conditions and reliability. These peak figures do not establish sustained application throughput over a busy multi-hop network.
