Underwater modems are used to transmit data wirelessly through water. With the introduction of underwater modems, users can now communicate, navigate and monitor under water. The use of technologies like Wi-Fi and GPS, beneath the water surface, has been made possible by the introduction of underwater modems. These are also known as acoustic modems. Underwater acoustic communication has low data rates due to the acoustic waves used for transmission rather than the electromagnetic waves. Underwater modems are used in a variety of applications for data gathering and monitoring for marine applications. Different modems are installed based on specific requirements like short-term deployment, long-term deployment and corrosion resistance. The use of underwater modems by the defense industry for communication between submarines is expected to drive the global underwater modem market. Incre’asing investments made in research and development and data monitoring underwater, surveys and environmental studies has led to further growth in the underwater modems market. Moreover, underwater modems are also used for autonomous under vehicle communication. The market for underwater modems is expected to increase at a moderate CAGR over the forecast period.

Market Restraints

The one issue that’s majorly impeding the growth of global underwater modems is that these modems function efficiently only up to a particular range and depth. This is one of the major restraints observed in the global underwater modems market.  That apart, there are other smaller issues too. Underwater modems suffer from the problem of multipath reflections which distort transmitted signals. Similarly, another restraint affecting the growth of global underwater is the high cost associated with underwater modems — the cost associated with deployment and maintenance of modems underwater is actually quite high. All of these factors, combined together, are proving to be a big challenge to the growth of the global underwater modems market.

Market Trends

The recent trends observed in the global underwater modems market are: these modems, nowadays, are available with the expanded memory option and data logger standards are also available. Another trend observed is that the global underwater modems are constructed with corrosion resistant materials to provide a longer lifespan and also to protect them from deterioration.
