About Us

Who are we?

Founded in 1995, Radio Data Networks (RDN) is leading in the drive to a more sustainable, safer, less polluted and smarter word by applying  Smart Sensing, Radio & Satellite Telemetry,  & IoT+ Solutions across a wide range of industries.  

RDN’s design team has has been responsible for the design and deployment of over 100,000 devices and the development of some of Europe’s largest Smart Networks for the Water, Gas, Environment & Rail industries. RDN’s IoT+ technology currently delivers circa 500 million data messages per year, mainly over RDN’s own private and secure licenced radio channels.

UK Design & Manufacture

Designed and Manufactured in the UK, our R&D team has accumulated 40 years of experience in Remote Monitoring,  Smart Sensors, Radio & Satellite Telemetry, Remote Control, Systems Build, and IoT+ Solutions with applications deployed in the water, wastewater, energy, industrial, agricultural, healthcare, transport, and environmental enforcement sectors.

Sentinel365 Smart Dashboard

The only dashboard to offer side-by-side monitoring and display of data delivered via multiple parallel communication media

  • Ofcom Licenced Radio
  • Iridium Satellite 
  • LoRaWAN
  • Cellular FTP, HTTP, etc. via GRPS, NB-IoT, Cat M1

The dashboard example below is from a EA-funded chalk stream flood mitigation programme, illustrating how real-time data can be used for both analytics and control.

Quality Assurance & Intellectual Property

Radio Data Networks is certified to ISO9001 and also BS/EN IEC 80069-34 for products to be used in potentially explosive atmospheres.

 When it comes to IP we have patented technology including smart sensors and flow regulators. Further, we have dozens of complete designs that form building blocks that permit complete systems and solutions to be created at minimal cost and delay. We own all the injection moulding & extrusion tools and PCB designs that we use. We own the source code to all embedded firmware used within our product portfolio permitting us to offer bespoke firmware, functions, and branding.

Award Winning Technology

RDN as been in receipt over over a dozen leading industry awards which is a testimony to its approach to innovation and sustainability. The latest in November 2022 was the double silver awards in the IET’s E&T innovation awards.

Our Technology

The disastrous consequences of global warming and climate change have never been more evident than today.  We are transforming businesses through our multi-award-winning smart sensing technology & IoT+ solutions to help them become greener, safer, and efficient, and ultimately reduce the risk and protect our ecosystems from environmental disasters.

RDN’s communication architecture RDNET and IoT+ is a unique radio and IoT hybrid that is compatible with the real world. Perfect for the creation of Smart Networks they support peer-to-peer, master-slave operations, where it has already replaced countless obsolete wired services, in the UK operates on our own exclusive, secure licenced radio channels, it has solutions for monitoring and controlling buried underground services, it has global reach via satellites, and via our Gateways, IoT+ embraces the modern world of the internet yet can equally deliver data to legacy systems without compromising cyber security.

Retrofittable, durability and testability, ease of use, and working out of the box are all part of the design culture that has underpinned our technology. A highly successful philosophy that has overcome barriers at all levels, gaining an unprecedented year-one adoption by the utility sector and subsequently leading to RDN winning several prestigious industry awards.

Ultra-Low or zero power is another essential. Our portfolio of real-time Smart Sensors, Controls, and Actuators are without exception, capable of long-term operation for batteries or solar, all in keeping with the drive for off-grid, net-zero operation.

Our solutions take us beyond simply populating dashboards with incidents. We have reached the next level, where the world and industries need to be, taking control.

  • Satellite Telemetry 
  • Real-Time Control Systems
  • Smart Sensors 
  • Flow Control Actuators 

RDN’s IoT+ technology has been adopted by government agencies ranging from the UK’s EA & NRW through to 7 major utilities, the UK’s NHS, industry, and agriculture.

In 2019 RDN was proud to become one of the founder members of the Zero Pollution Network and foundation a Green Technology charity/organization to promote and fund pollution reduction technologies

RDN’s portfolio includes  Smart Sensors, Low Energy Actuators, Radio Telemetry, Satellite, and Cellular IoT. to deliver solutions across the Water, Wastewater, Environmental, Utility (Gas & Electricity), Agriculture, Mining, Commercial, Industrial, and Transport Sectors.

RDN’s smart solutions are used widely across the UK, the Channel Islands, and parts of Europe to deliver a variety of monitoring and control solutions to help prevent pollution including the spill of plastics into the oceans, cut leakage from water distribution networks, improve industrial and agricultural process efficiency, reduce carbon footprints, to prevent the spread of infection in healthcare, report, and control flooding, mitigate spills, provide security, control flows and to deliver environmental status reports, including those concerning spills of sewage into bathing waters for circa 1,400km of beaches.

How we Communicate

We offer our clients the choice of communications, scaled towards the safety integrity of service required and the remoteness of the location of deployment.

The choice includes:

  • Ofcom Licensed Radio – For high SIL local networks, radio telemetry, and real-time control.
  • Iridium Satellite – For remote and high SIL monitoring from cellular not-spots 
  • LoRaWAN – for low-risk general-purpose monitoring where the loss of data can be tolerated
