Pioneering the ‘internet of underwater things’

An underwater wireless network could transform how we understand and manage ocean resources

Spotted: The blue economy encompasses all economic activities involving our oceans and seas, and it’s estimated to be worth more than $1.5 trillion per year globally – with that figure expected to double by 2030. 

The newest addition to the blue economy is a subsea Wi-Fi technology that enables real-time, secure, and cost-effective wireless communications underwater. Developed by Sapienza University spinoff WSense, the system makes it possible to collect underwater data at a much greater scale than previously achievable. 

WSense describes its system as an “Internet of Underwater Things”. It consists of shallow and deepwater hardware, including sensors and robotics, and software, which connect to form a wireless undersea internet network infrastructure. The system, which can operate at up to 3,000 metres deep, allows real-time monitoring of aspects of the marine environment such as water quality, noise pollution, currents, movement of structures, and more. 

In addition to providing data for research, WSense’s system could be used to monitor underwater infrastructure and moorings, aid the energy transition, and provide real-time environmental monitoring and sustainable, data-driven aquaculture. 

WSense recently closed a series A funding round which raised €9 million, bringing the company’s total equity funding to more than €13 million. The money will be used to boost international expansion and growth, especially in Europe and the Middle East. 

Other ways IoT is helping deliver sustainability include a system for smarter waste management and a network that helps improve urban health and safety.
