No. Radio frequency is an electromagnetic phenomenon and it is not interrupted/interfered by acoustics/sound waves.
Technically electrical fields don’t go through water but magnetic fields do. We use magnetic fields. Historically people thought it impractical to communicate data and power through sea water, because so much of the electromagnetic energy ends up absorbed or ‘attenuated’ by the sea. At WFS we see it differently. A lot of signal does get attenuated, but if signal, power, distance, data speed and wavelength are all optimally configured, it is still possible to use underwater wireless to deliver high bandwidths and power levels over short distances. This delivers benefits for many applications in the subsea industry.
What are the benefits of using radio signals for subsea wireless communication? Can provide data rates of up to 100 Mbps Immune to acoustic noise Immune to marine fouling Unaffected by water depth Unaffected by turbidity/bubbles Omnidirectional performance Can transit water/air interface Can transmit through the seabed
We will happily supply you with OEM versions of WFS products (and additional Engineering support if required) so that you can integrate and expand the capability of your end product.
Our communication systems do not interfere with other equipment either in air or subsea. Some care needs to be taken with the integration of wireless power transfer equipment, this is covered in our user manuals and we can provide design support.
Subsea wireless technology has the distinct advantage that it will operate in adverse water conditions, is unaffected by acoustic noise, operational in shallow water, is immune to multipath and its Doppler effects are minimal.
WFS have developed our modulation schemes using techniques developed for the mobile phone industry.
WFS maintain competitive advantage by making intellectual property a key part of our business. We have over 200 patent applications worldwide (over 75 of which have been granted to date). We are continually innovating and will defend or enforce our IP rights. This gives our customers and partners confidence that they are dealing with world experts who have a strong competitive position. We welcome the opportunity to work with other parties to further innovation in wireless technology. In undertaking these collaborations WFS respects the IP rights of others and can license its own IP rights.
Depending on your application, what product you choose, and how much data you require, you can achieve a range of up to 50m in seawater with standard Seatooth® underwater wireless products. This can be extended if required by adapting the antenna/power configuration.
Seatooth® products come in three standard depth-ratings: 350m, 1,000m and 4000m. We can supply systems to be deployed in deep-water if required.
In addition to our modems, dataloggers, controllers, and connectors, there still more ways that you can work with WFS. You can purchase anything from standard subsea wireless communications product to a custom engineering solution for your project. You can work with us to investigate a possible subsea wireless solution to your application with a feasibility study, or if you want to add wireless capability to an existing product you could license our Intellectual Property or integrate our OEM systems.
This depends on your application. Some of our standard products are available to buy online; more complex and bespoke solutions will be priced by us once we understand your requirements. Please visit our online shop or contact us for a quote.
WFS is a founding member of the Subsea Wireless Group (www.subseawirelessgroup.com), an industry initiative focusing on development of open standards for wireless communications underwater and implementation of wireless solutions for a range of industry priorities. SWIG works to define standards that facilitate interoperability between subsea wireless technologies (acoustic, radio frequency, free space optics). SWiG engages with standards bodies, encourages the integration of wireless technologies, and promotes best practices across the subsea industry. More information can be found here: http://www.subseawirelessgroup.com/
We have supplied standard products and custom solutions to projects in Europe, Asia, Australasia, West Africa and North America. In some cases we work with trusted partners. We encourage you to contact us, wherever you are in the world, and we will find the best way to help.
