Announcing the world’s highest performance underwater acoustic modems (30th Oct, 2020): The Aquacomm Gen2 modems can now operate  below the noise floor at -10db to -15db SNR with +/-10knots Doppler compensation in highly reflective and noisy environments.

This allows customers to deploy underwater wireless data links even in the most harsh environments such as high noise sub-sea oil and gas projects, shallow and noisy environments as well as in highly reflective concrete or metal structures such as pools or tanks. We challenge any competitor modem to beat our performance in any difficult underwater application.

We offer these ground breaking products at a reasonable cost for the evaluation stage and at low cost in volume. We understand the needs of the OEM for high volume applications.

Aquacomm Gen2: Next Generation Underwater Wireless Modem

Home Aquacomm Gen2: Next Generation Underwater Wireless Modem

Aquacomm Gen2 is the latest generation underwater wireless modem built on the highly reliable and proven spread spectrum communications algorithms. Utilizing the latest generation power efficient floating point DSPs to offer high dynamic range and flexibility to enhance performance. This underwater wireless modem can work in a bucket of water to the deep ocean. We have proven the Gen2 underwater wireless modem over 8km distance in harsh shallow water environments.
