Underwater Acoustic Communication Market-Increasing Underwater Exploration Activities Especially For Environmental Protection

Underwater Acoustic Communication Market: Overview

Underwater acoustic communication is a method of sending and receiving messages under water. Underwater communication can be commissioned in a number of ways; however, hydrophone is the most commonly used method. Generally, underwater communication is complicated, as it involves numerous challenges such as channel time variations, multi-path propagation, minimal present bandwidth, and significant long range signal attenuation. Underwater acoustic communication is different from terrestrial communication, as it has low data rates and uses acoustic waves in place of electromagnetic waves. In underwater acoustic communication, communication sound waves are used for superior communication because they travel underwater with ease. Underwater acoustic communication involves the underwater propagation of sound and mechanical waves interactions that create sound with the water. The water might be from a lake or ocean, or a tank. Generally, the frequencies related with underwater acoustics communication are in the range of 10 Hz and 1 MHz.  Sound propagation inside the ocean with lower frequencies i.e. less than 10 Hz is normally impossible without deep sea penetration. However, frequencies more than 1 MHz are rarely used because of their quick absorption.

Underwater Acoustic Communication Market: Drivers and Restraints

Increasing underwater exploration activities especially for environmental protection, and rising demand for high speed and consistent defense and homeland security communication is expected to fuel the growth of the underwater acoustic communication market. For superior underwater communication, underwater acoustic networks having a very high capacity are required. Underwater networks involve large quantity of deployed vehicles and sensors. Underwater acoustic communication can be used for oceanographic data gathering, offshore exploration, pollution monitoring, and strategic applications pertaining to surveillance. Additionally, it also finds high usage across autonomous or unmanned underwater vehicles equipped with sensors. Typically, unmanned underwater vehicles largely are used in natural undersea resources exploration and in collection of critical data in the missions related to collaborative monitoring.
